Product Data 0GTS,GTU Air-Cooled Reciprocating Liquid Chillers withcomfortlink Controls Hz Nominal Capacities: to 410 Tons 17 to 154 kw Features/Benefits ComfortLink control Your link to a world of simple and easy to use air-cooled chillers that offer out-standing performance and value. The 0GTS,GTU liquid chillers employ more than the latest advanced micro-processor controls, they utilize an expandable platform that grows as your needs change. From stand-alone operation to remotely monitored and oper-ated multi-chiller plants, ComfortLink controls can keep you plugged in. ComfortLink controls are fully communicating, and are cable ready for connection to a Carrier Comfort Network (CCN). Occupancy scheduling, temperature and pressure read-outs, and the ComfortLink scrolling marquee clear language display compliment the standard features, linking you to a world of carefree comfort. The 0GTS,GTU chillers are built on the legendary performance of the Carrier model 0G Flotronic chiller and share many of the same time-proven features and technologies providing easy operation, quick installation and start-ups that save you money! Superior temperature control equals potential for greater productivity Whether in the classroom, on the production floor, or in the office, ComfortLink controls can help you to adapt to changing weather and business conditions. Accurate temperature control provided by the Carrier ComfortLink system helps to maintain higher levels of indoor air quality, thermal comfort, and productivity space. While many air-cooled chillers use only leaving fluid temperature control, the 0GTS,GTU chillers utilize leaving fluid temperature control with a standard entering fluid temperature
compensation. This Carrier exclusive provides smart control and intelligent machine capacity staging. Unlike many chillers, Carrier model 0GTS,GTU chillers do not require constant fluid flow. The ability to operate with variable flow also allows building owners to realize even greater overall system energy savings in the chilled water pumping system of up to 85%, and not just at the chiller Energy management made easy While 0GTS,GTU chillers have many standard features such as network communications capability and temperature reset based on return fluid temperature, they can also expand as needs change. Supply temperature reset based on outside air or space temperature is as easy as adding a thermistor. The Energy Management option can allow you to take advantage of changing utility rate structures with easy to use load shedding, demand limiting and temperature reset capabilities. Reset triggered via 4 to 0 ma signal makes integrating from an existing building management system simple. The ComfortLink platform can be expanded further with the Service Option which has all of the features of the Energy Management option, along with an additional hand-held ComfortLink Navigator display and remote service connection port. While providing additional information in a clear language format, the Navigator display can be plugged into the unit at either the control panel or at the remote service port, allowing the service technician to operate the unit from where the maintenance or service work is being performed, thereby minimizing downtime to ensure the system is ready for operation in the shortest amount of time. Both the Energy Man-agement and Service Options can be factory-supplied or can be added in the field at a later date as needs change. Full and part load efficiency advantage The 0GTS,GTU chillers with ComfortLink control offer outstanding efficiencies (EER [Energy Efficiency Ratio], COP [coefficient of performance], and IPLV [integrated part load value]) in both full and part load operation. Increased part load efficiency is provided by dual independent refrigeration circuits, suction cut-off unloading, and return fluid temperature compensation. The fully integrated ComfortLink control system maintains efficient control over the compressors, unloaders, expansion valves, and condenser fans to optimize performance as conditions change. The Carrier exclusive long-stroke electronic expansion valve (EXV) operates at reduced condensing pressures, thereby allowing the control to operate the fans down to lower outdoor temperatures. By utilizing valve position information, the control maintains the highest possible evaporator pressure and minimizes the excessive superheat that conventional thermal expansion valve (TXV) systems require. Wider operating ranges equal increased efficiencies and lower installed costs. Building design flexibility Design and consulting engineers will appreciate the broad selection of sizes and wide operating range offered by the 0GTS,GTU chillers. With built-in dual chiller control, imaginative large tonnage systems can be easily engineered and controlled with smaller, easier to handle modules. Modular design allows engineers to consider side by side, offset, or angled placement to fit the awkward spaces that the architect sometimes leaves for mechanical systems. Or, in the case of planned expansion, additional cooling can be brought on-line and controlled from the same system. In some places facility managers may find that the cash flow provided by building up large air cooled multi-chiller plants can easily offset any efficiency losses when compared to large water cooled centrifugal type chilled water plants. Quality and reliability To assure long life and quality performance, every chiller is factory run tested at full load. Individual components are also tested at many levels to assure that only the best parts make it into Table of contents 0GTS,GTU chillers. Long life and reliability are also a function of design. While some manufacturers like to talk about moving parts, Carrier s engineers recognized the potential dangers to chiller systems caused by problems in the power distribution system. Low voltage and phase imbalances are but a few of the conditions that can hurt the compressor s motor. Model 0G chillers were one of the first to offer ground current sensing to prevent compressor motor burn-out that would contaminate the system and potentially threaten the life of future replacement compressors. The 06E semi-hermetic compressors are built for performance and have proven themselves in commercial refrigeration equipment worldwide. With tens of thousands of chillers operating in all corners of the world, endusers count on the reliability of Carrier 0G chillers. The Carrier Malaysia plant is an ISO 9001 registered facility as are many of Carrier s other component and assembly plants throughout the Features Simple and easy to use ComfortLink communicating controls.

Application Data Leveling Unit Unit must be level within 1/8-in. per ft when installed to ensure proper oil return to the compressors. While most outdoor locations are suitable for 0GTS, GTU units, the roof is a common site that presents a problem if roof has been pitched to aid in water removal. To assure proper oil return, be sure that unit is level, particu-larly in its major lengthwise dimension, as compressor oil return piping runs in that direction. It should be determined prior to installation if any special treatment is required to assure a level installation. Cooler fluid temperature 1. Maximum leaving chilled fluid temperature (LCWT) for unit is 70 F (1 C). Unit can start and pull down with up to 95 F (5 C) entering-fluid temperature due to MOP (maximum operating pressure) feature of the TXV. For sustained operation, it is recommended that entering-fluid temperature not exceed 85 F (9.4 C).. Minimum LCWT for standard unit is 40 F (. C). It is permissible to use a standard microprocessor-controlled ComfortLink chiller with leaving-fluid temperatures in the range of 4 to 9.9 F (1 to.8 C) only if a protective brine solution (0% anti-freeze solution, or greater) is used. (See Controls and Troubleshooting literature for further information.) Leaving-fluid temperature reset The Energy Management Module (EMM) is required for 4 to 0 ma reset of LCWT in constant fluid systems. Reset by return fluid, outdoor-air temperature, or space temperature does not require this option. Reset reduces compressor power usage at part load when design LCWT is not necessary. Humidity control should be considered since higher coil temperatures resulting from reset will reduce latent heat capacity. Three reset options are offered, based on the following: Return-fluid temperature Increases LCWT temperature set point as return (or entering) fluid temperature decreases (indicating load decrease). Option may be used in any application where return fluid provides accurate load indication. Limitation of return fluid reset is that LCWT may only be reset to value of design return fluid temperature. Outdoor-air temperature Increases LCWT as out-door ambient temperature decreases (indicating load decrease). This reset should be applied only where outdoor ambient temperature is an accurate indication of load. An accessory thermistor is required. Space temperature Increases LCWT as space temperature decreases (indicating load decrease). This reset should be applied only where space temperature is an accurate indication of load. An accessory thermistor is required. For details on applying a reset option, refer to unit Controls and Troubleshooting literature. Obtain ordering part numbers for reset option from current price pages or contact your local Carrier representative. Cooler flow range Ratings and performance data in this publication are for a cooling temperature rise of 10 F (6 C), and are suitable for a range from 5 to 0 F (.8 to 11.1 C) temperature rise without adjustment. The ComfortLink chillers may be operated using a different temperature range, provided flow limits are not exceeded. For minimum flow rates, see Minimum Cooler Fluid Flow Rates and Minimum Loop Volume table. High flow rate is limited by pressure drop that can be tolerated. If another temperature range is used, apply LCWT correction.

Application Data (cont) Minimum cooler flow (maximum cooler temperature rise) The minimum cooler flow for standard units is shown in Minimum Cooler Fluid Flow Rates and Minimum Loop Volume tables. When gpm (L/s) required is lower (or rise higher), follow recommendations below: a) Multiple smaller chillers may be applied in series, each providing a portion of the design temperature rise. b) Cooler fluid may be re-circulated to raise flow rate. However, mixed temperature entering cooler must be maintained a minimum of at least 5 F (.8 C) above the LCWT. c) Special cooler baffling is required to allow minimum flow rate to be reduced. Fluid loop volume The volume in circulation must equal or exceed gal. per nominal ton (.5 L per kw) of cooling for temperature stability and accuracy in normal airconditioning applications. (For example, a 0GTS10 would require 60 gal. [ L].) In process cooling applications, or for operation at ambient temperature below F (0 C) with low loading conditions, there should be from 6 to 10 gal. per ton (6.5 to 10.8 L per kw). To achieve this volume, it is often necessary to install a tank in the loop. Tank should be baffled to ensure there is no stratification and that water (or brine) entering tank is adequately mixed with liquid in the tank. NOTE: Tank installation is shown below. NOTE: Recirculation flow is shown below. Maximum cooler flow The maximum cooler flow (> 5 gpm/ton or < 5 F rise [> 0.09 L/s kw or <.7 C rise]) results in practical maximum pressure drop through cooler. 1. Return fluid may bypass the cooler to keep pressure drop through cooler within acceptable limits. This permits a higher T with lower fluid flow through cooler and mixing after the cooler.. Special cooler baffling to permit a cooler flow rate increase of 10% is available by special order. NOTE: Bypass flow is shown below. Variable cooler flow rates Variable rates may be applied to standard chiller. Unit will, however, attempt to maintain a constant leaving chilled fluid temperature. In such cases, minimum flow must be in excess of minimum flow given in Minimum Cooler Fluid Flow Rates and Minimum Loop Volume table, and flow rate must change in steps of less than 10% per minute. Apply 6 gal. per ton (6.5 L per kw) water loop volume minimum if flow rate changes more rapidly. Cooler fouling factor The fouling factor used to cal-culate tabulated ratings was.00010 ft hr F/ Btu (.000018 m C/W). As fouling factor is increased, unit capacity decreases and compressor power increases. Standard ratings should be corrected using following multipliers: FOULING FACTOR English (ft² hr F/Btu).0005.000.00075.00175 SI (m² C/W).000044.000088.0001.00008 CAPACITY MULTIPLIER 0.991 0.977 0.955 0.910 COMPRESSOR POWER MULTIPLIER 0.995 0.987 0.979 0.95 Cooler protection Protection against low ambient freeze-up is required for unit operation in areas that experience temperatures below F (0 C). Protection should be in the form of inhibited ethylene glycol or other suitable brine. Even though unit cooler is equipped with insulation and an electric heater that helps prevent freeze-up, it does not protect fluid piping external to unit or if there is a power failure. Use only antifreeze solutions approved for heat exchanger duty. Use of automotive-type antifreezes is not recommended because of the fouling that can occur once their relatively short-lived inhibitor breaks down. Draining cooler and outdoor piping is recommended if system is not to be used during freezing weather conditions. 7

Pa 0.0 5 CAPACITY MULTIPLIER 1.000 0.986 0.968 COMPRESSOR POWER MULTIPLIER 1.00 1.01 1.0 High-static fan options These should be used to prevent a reduction in airflow to the conditioned space whenever an application requires external ductwork which will raise the job static requirements. High ambient temperature High outdoor ambient chiller start-up and operation (fully loaded) is possible for standard 0GTS,GTU chillers at ambient temperatures up to 15 F (5 C) at nominal voltage. In some cases, where return water temperature is expected to exceed 60 F (.5 C), an accessory kit may be required. Oversizing Chillers Oversizing chillers by more than % at design conditions must be avoided as the system operating efficiency is adversely affected (resulting in greater or excessive electrical demand). When future expansion of equipment is anticipated, install a single chiller to meet present load requirements and add a second chiller to meet the additional load demand. It is also recommended that smaller chillers be installed where operation at minimum load is critical. The operation of a smaller chiller loaded to a greater percentage over minimum is preferred to operating a single chiller at or near its minimum recommended value. Hot gas bypass should not be used as a means to allow oversizing chillers. Hot gas bypass should be given considerations where substantial operating time is anticipated below the minimum unloading step. Multiple chillers Where chiller capacities greater than 10 tons (740 kw) are required, or where stand-by capability is desired, chillers may be installed in parallel. Units should be of equal size to ensure balanced fluid flows. Where a large tempera-ture drop (> 5 F [1.9 C]) is desired, chillers may be installed in series. Fluid temperature sensors need not be moved for multiple chiller operation. A 10 ft ( m) separation is required between units for airflow, and a 6 ft (1.8 m) distance is required from units to obstructions. See Multiple Unit Separation figure below. Unit software is capable of controlling two units as a single plant. Refer to Controls, Start-Up, Operation, Service, and Troubleshooting guide for further details. 8
Application Data (cont) Electrical/utility interests Energy management Use of energy management practices can significantly reduce operating costs, especially during off-peak modes of operation. Demand limiting and temperature reset are techniques for accomplishing efficient energy management. See Demand Limiting (also called load shedding) section below and Leaving-Fluid Temperature Reset section on page 6 for further details. Demand limiting (also called load shedding) When a utility s demand for electricity exceeds a certain level, loads are shed to keep electricity demand below a prescribed maximum level. Typically, this happens on hot days when air conditioning is most needed. The Energy Management Module (EMM) can be added to accomplish this reduction. Demand may be limited on unit by resetting fluid temperature, or by unloading the chiller to a given predeter-mined percentage of the load. Demand limit may also be driven by an external 4 to 0 ma signal. These features require a signal from an intelligent central control. Do not cycle demand limiter for less than 10 minutes on and 5 minutes off. Duty cycling cycles electrical loads at regular intervals regardless of need. This reduces the electrical operating costs of building by fooling demand indicating devices. Duty cycling of compressors or fans is not recommended since motor winding and bearing life suffer from constant cycling. Remote on-off control Remote on-off control may be applied by hard-wired connection (see Controls and Troubleshooting literature) or by connection to a Carrier Comfort Network (CCN). Part-wind start This is not generally required on 0GTS, GTU chillers due to use of multiple compressors allowing smaller electrical load increments, but is available if required. Strainers It is recommended that a strainer with a minimum of 0 mesh be installed in the cooler fluid inlet line, just ahead of and as close as possible to the cooler. Condenser coil protection Pre-coated aluminum-fin coils have a durable epoxy and polyurethane coating applied to the fin prior to the finstamping process to provide protection in mildly corrosive coastal environments. This economical option provides substantial corrosion protection beyond the standard uncoated coil construction. Post-coated aluminum-fin coils have a Blygold Polual coating (Aluminum hydroxide 5~0 microns thickness) uniformly applied to all coil surface Coated coils shall withstaed 0-hour salt spray in accordance with ASTM (USA) B117 and may be used to provide protection in heavy coastal environments. Copper-fin coils provide increased corrosion resistance in moderate coastal environments where industrial air pollution is not present. All copper coils eliminate bimetallic construction to eliminate the potential for galvanic corrosion. Application in industrial environments is not recommended due to potential attack from sulfur, sulfur oxide, nitrogen oxides, carbon and several other industrial airborne contaminants. In moderate seacoast environments, copperfin coils have extended life compared to standard or precoated aluminum-fin coils.

Controls Microprocessor The ComfortLink microprocessor controls overall unit operation. Its central executive routine controls a number of processes simultaneously. These include internal timers, reading inputs, analog to digital conversions, fan control, display control, diagnostic control, output relay control, demand limit, capacity control, head pressure control, and temperature reset. Some processes are updated almost continuously, others every to seconds, and some every 0 seconds. The microprocessor routine is started by switching the Emergency ON-OFF circuit breaker switch (switch ) to ON position. When the unit receives a call for cooling (either from the internal control or CCN network command), the unit stages up in capacity to maintain the cooler fluid set point. The first compressor starts 11/ to minutes after the call for cooling. The lead circuit can be specifically designated or randomly selected by the controls, depending on how the unit is field configured. A field configuration is also available to determine if the unit should stage up both circuits equally or load one circuit completely before bringing on the other. The ComfortLink microprocessor controls the capacity of the chiller by cycling compressors on and off at a rate to satisfy actual dynamic load conditions. The control maintains leavingfluid temperature set point shown on scrolling marquee display board through intelligent cycling of compressors. Accuracy depends on loop volume, loop flow rate, load, outdoor-air temperature, number of stages, and particular stage being cycled off. No adjustment for cooling range or cooler flow rate is required, because the control automatically compensates for cooling range by measuring both return-fluid temperature and leaving-fluid temperature. This is referred to as leaving-fluid temperature control with return-fluid temperature compensation. The basic logic for determining when to add or remove a stage is a time band integration of deviation from set point plus rate of change of leaving-fluid temperature. When leaving-fluid temperature is close to set point and slowly moving closer, logic prevents addition of another stage. If leaving-fluid temperature is less than 4 F (1.1 C) for water, or 6 F (. C) below the set point for brine units, the unit is shut off until the fluid temperature goes to 4 F (1.1 C) or to 6 F (. C) above the set point to protect against freezing. If 1 F per minute (0.6 C per minute) pulldown control has been selected (factory setting), no additional steps of capacity are added as long as difference between leaving-fluid temperature and set point is greater than 4 F (. C) and rate of change in leaving-fluid temperature is less than 1 F per minute (0.6 C per minute). If it has been less than 90 seconds since the last capacity change, compressors will continue to run unless a safety device trips. This prevents rapid cycling and also helps return oil during short on periods. Lead/lag operation can be configured to balance compressor operating hours when set to automatic. When lead/lag operation is configured to automatic, a compressor wear factor is used to determine which circuit to start first by utilizing a combination of actual run hours and number of starts. Lag compressors in a circuit would also be started to maintain even wear factors. Either circuit can be set to always lead, if desired. The control also performs other special functions when turning on or off. When a circuit is to be turned off, EXV or LLSV (TXV units) is closed first, and compressor is run until conditions are met to terminate pumpout to remove refrigerant that was in the cooler. At start-up, if a circuit has not run in the last minutes, circuit is run to remove any refrigerant that has migrated to the cooler. The oil pressure switch is bypassed for minutes during start-up and for 1 minute during normal operation. Thermistors Eight thermistors are used for temperature-sensing inputs to microprocessor. (A ninth [T9] and/or tenth [T10] may be used as a remote temperature sensor for optional LCWT reset.) T1 Cooler leaving chilled fluid temperature T Cooler entering fluid (return) temperature T Saturated condensing temperature Circuit A T4 Saturated condensing temperature Circuit B T5 Cooler saturation temperature Circuit A T6 Cooler saturation temperature Circuit B T7 Return gas temperature entering compressor cylinder Circuit A T8 Return gas temperature entering compressor cylinder Circuit B T9 Outdoor air temperature sensor (accessory) T10 Remote space temperature sensor (accessory) The microprocessor uses these temperatures to control capacity, fan cycling, and EXV operation. Electronic expansion valve (EXV) To control flow of refrigerant for different operating conditions, EXV piston moves up and down over slot orifices through which refrigerant flows to modulate size of opening. Piston is moved by a stepper motor through 1 discrete steps. The piston is repositioned by the microprocessor every seconds as required. The EXV is used to control superheat in compressor. The difference between thermistors (compressor return gas temperature minus cooler saturation temperature) is used to determine superheat. The EXV is controlled to maintain superheat entering pistons at approximately 9 F (16.1 C), which results in slightly superheated refrigerant leaving cooler. The electronic control provides for a prepurge and pumpout cycle each time the lead compressor in a circuit is started or stopped. These pumpout cycles minimize amount of excess refrigerant that can go to compressor on start-up and cause oil dilution (which would result in eventual bearing wear). The microprocessor software is programmed so that EXV functions as an MOP (maximum operating pressure) valve, limiting the suction temperatures to 55 F (1.8 C). This makes it possible to start unit at high fluid tempera-tures, up to 95 F (5 C), without overloading compressor. Another feature that is factory set (can be reconfigured in the field) limits rate of pulldown to 1 F (0.6 C) per minute, thereby reducing the kw demand on start-up. 47
Controls (cont) Accessory controls Demand can be further limited by keeping a selected number of compressors from turning on by utilizing demand limit control (the Energy Management Module is required for this function). This FIOP/accessory interfaces with microprocessor to control unit so that chiller s kw demand does not exceed its setting. It is activated from an external switch. The standard ComfortLink control is programmed to accept various accessory temperature reset options (based on returnfluid temperature, outdoor-air temperature, or space temperature), that reset the LCWT. An accessory thermistor (T9 or T10) is required if outdoor-air temperature or space temperature reset is selected. The Energy Management Module (EMM) is only required for temperature reset that is initiated by a 4 to 0 ma signal. Ground current protection The 080-10 and 070 ( Hz) sizes have ground current protection that shuts off compressor(s) if a to amp ground current is sensed by a toroid around the compressor power leads. 0GTS,GTU ComfortLink controls with Scrolling Marquee display module A standard four-digit alphanumeric display shows all of the ComfortLink control codes (with expandable clear language), plus set points, time of day, temperatures, pressures, and superheat. Additional information can be displayed all at once with the Navigator display. Control sequence Off cycle During unit off cycle, crankcase heater is energized. If ambient temperature is below 6 F ( C), cooler heaters (if equipped) are also energized. Electronic expansion valves are closed. Start-up After control circuit switches on, prestart process takes place, then microprocessor checks itself and waits for temperature to stabilize. First circuit to start may be A or B (automatic lead/lag feature). The controlled pull-down feature limits compressor loading on start-up to reduce demand on start-up and unnecessary compressor usage. The microprocessor limits supply-fluid temperature decrease (startup only) to 1 F (0.6 C) per minute. Capacity control On first call for cooling, microprocessor starts initial compressor and fan stage on lead circuit. The EXV remains closed, permitting a pumpouton start-up. After pumpout, the valves open and, if necessary, additional outdoor fans are energized. Crankcase heaters are de-energized when a compressor is started. As additional cooling is required, lag circuit starts. If further cooling is needed, compressors are added, alternating between lead and lag circuits. Speed at which capacity is added or decreased is controlled by temperature deviation from set point and rate of temperature change of chilled fluid. Aslesscooling is required, circuits shut down (or unload) in an order that balances each circuit s compressor run time (depending upon configuration). When no further cooling is called for (in each compressor circuit), EXV closes and compressor and fans continue to run while pumping down cooler. Control features Low-temperature overridethis feature prevents LCWT from overshooting the set point and possibly causing a nuisance trip-out by the freeze protection. High-temperature overridethis feature allows chiller to add capacity quickly during rapid load variations. Demand limitif applied, limits the total power draw of unit to selected point by controlling number of operational compressors during periods of peak electrical demand. The Energy Management Module is required for either -stage or 4 to 0 ma demand limit. Temperature reset If applied, microprocessor compares either return fluid, space temperature, or outdoor-air temperature with the accessory board settings, and adjusts LCWT appropriately. The Energy Management Module can also be added for 4 to 0 ma reset. Electronic expansion valve and condenser-fan con trol The EXV opens and closes on signal from micro-processor to maintain an approximate 9 F (16 C) refrigerant superheat entering the compressor cylinders. (The compressor motor increases the refrigerant superheat from the approximate 5 F [ C] leaving the cooler to that entering the cylinders.) Condenser fans (operated by microprocessor) run to as low an ambient as possible to maintain a minimum EXV pressure differential. Abnormal conditions All control safeties in chiller operate through compressor protection board or control relay and microprocessor. Highpressure switch directly shuts down compressor(s) through compressor protection board or control relay. For other safeties, microprocessor makes appropriate decision to shut down a compressor due to a safety trip or bad sensor reading and displays appropriate failure code on the display. Chiller holds in safety mode until reset. It then reverts to normal control when unit is reset. Oil pressure safetysafety cuts out if pressure differential is below minimum (accessory on sizes 0-070). Safety is bypassed on start-up for minutes. Loss-of-charge safety Safety cuts out if system pressure drops below minimum. High-pressure cutout Switch shuts down compressors if compressor discharge pressure increases to 46 psig (918 kpa). Ground current safety Safety opens on sensing a current-to-ground in compressor windings in excess of.5 amps. Compressor anti-cycling This feature limits compressor cycling. Loss of flow protectionadditional protection is provided by temperature differences between entering and leaving fluid temperature sensors if cooler temperature drops to 4 F (1.1 C). Proof of flow switches are recommended. Sensor failures Failures are detected by the microprocessor. 48
Controls (cont) Diagnostics Microprocessor may be put through service test (see Controls, Start-Up, Operation, Service and Troubleshooting literature) without additional equipment or tools. Service test confirms microprocessor is functional, informs observer through display the condition of each sensor and switch in chiller, and allows observer to check for proper operation of fans and compressor(s). Default settings To facilitate quick start-ups, all 0GTS,GTU chillers with ComfortLink controls are pre-configured with a default setting that assumes stand-alone operation supplying 44 F (6.7 C) chilled water. Configuration setting will be based on any options or accessories included with the unit at the time of manufac-turing. Date and time and will need reconfiguring based on location and local time zone. If operation based on occupancy scheduling is desired, this will also need to be set during installation. 49
