Thermostat shall be supplied (without networking interface, BACnet MS_TP network interface, Echelon Lontalk network interface, Zigbee wireless network interface). BACnet MS/TP versions shall be provided with Protocol Implementation Conformance Statement or Lonmark approval disclosing all object/snvt properties and instance numbers to facilitate the integration process. Echelon-Lontalk Communicating versions shall be provided with appropriate application files and LNS plug-in as required free of charge from the manufacturer. Thermostat shall utilize EEPROM memory to back up local configuration parameters in the event of power failure. Thermostats requiring batteries, or have no provisions for retention during loss of power shall not be acceptable. Thermostat shall have integrated changeover function, which will allow seamless switching between cooling and heating mode based upon temperature or network value input. Thermostat shall be provided with two (2) floating or two (2) analog proportional-integral control outputs and one configurable auxiliary output to be used for heating, or local digital output. Thermostat shall be compatible with the Viconics VI-PIR Passive Infrared cover for advanced active occupancy logic. An additional occupancy level Stand-by shall be added between occupied and unoccupied modes for additional energy savings strategies. The thermostat can be retrofitted with the VI-PIR cover on site.
Thermostat shall be capable of local or remote override during unoccupied mode. The thermostat shall resume occupied setpoints and will revert back to unoccupied setpoints after a certain amount of time (adjustable from 0 24hours in one hour increments). Thermostat shall have configurable temporary or permanent local override setpoints. When the temporary setpoints mode is enabled, once the temporary occupancy timer expires, the setpoints will revert back to their default values. Thermostat shall have four (4) adjustable keypad lockout levels limiting access to changes of occupied and unoccupied setpoints. Thermostat shall have adjustable local unoccupied heating and cooling setpoint limits as well as maximum heating and minimum cooling limits. Thermostat shall have an adjustable deadband (from 2 F to 5 F in 1 increments, 1 C to 2.5 C in 0.5 increments). Thermostat shall provide the following local monitoring capabilities: DI-1 1. None: No function will be associated with the input (free input to be used for alarming or monitoring of a remote digital contact to be shared over a communications network). 2. Remote Night Setback: Remote night setback timer clock input. Scheduling shall be set as per the binary input providing low cost setback operation via a dry contact. 3. Motion NO and Motion NC: Advanced PIR occupancy functions using Normally Open (NO) or Normally Closed (NC) remote PIR motion sensor. Occupancy mode shall be set as per applied PIR function and configuration 4. EMS: Door/window strategy. Shall display an alarm if door/window is open and thus heating/cooling has stopped. DI-2 1. None: No function will be associated with the input (free input to be used for alarming or monitoring of a remote digital contact to be shared over a communications network). 2. (Door Dry) Door contact & Motion detector: This configuration is only functional if binary input #1 is set to Motion NO or Motion NC or a PIR accessory cover is used. When sequence is enabled, the occupancy shall be dictated through 2 inputs. Any motion detected shall set the zone to occupied status. The zone shall remain permanently in occupied mode until the door contact switch opens momentarily. The thermostat shall then go in stand-by mode. If more movements are detected, the occupied mode shall resume. While the door is opened, any movements detected by the remote PIR sensor or the PIR accessory cover shall be ignored. 3. Remote Override: Temporary occupancy remote override contact. Local keypad override shall be disabled. Override function shall be controlled only by a manual remote toggle signal. 4. Filter: A backlit flashing Filter alarm shall be displayed on the local thermostat LCD screen when input (from a differential pressure switch) is energized. 5. Service: A backlit flashing Service alarm shall be displayed on the local thermostat LCD screen when input (ex. rooftop unit malfunction) is energized. UI-3 1. None: No function will be associated with the input (free input to be used for monitoring of a remote 10k type II thermistor (discharge air, outside air, return air etc.) to be shared over a communications network) 2. COC/NH: Change over dry contact - Normally Heat: For two-pipe systems 3. COC/NC: Change over dry contact - Normally Cool: For two-pipe systems 4. (COS): Change over analog sensor: For two-pipe systems 5. (SS) Supply air sensor monitoring: Used for supply air temperature monitoring.
Thermostat shall be provided with six unique sequences to meet the needs of most zone temperature control applications. Sequence Mode Menu 0 = Cooling only Off - Cool 1 = Heating only Off - Heat 2 = Cooling with reheat Off Auto Heat Cool 3 = Heating with reheat Off - Heat 4 = Cooling and Heating (2 modulating outputs) Off Auto Heat Cool 5 = Cooling / Heating (2 modulating outputs) Off Auto Heat Cool with reheat Thermostat shall be pre-programmed, containing all required I/O to accomplish local HVAC temperature control. Thermostats shall be provided with intelligent HMI, to which will display services only as are available as switched through local digital input or network layer such as: Outdoor air temperature display only enabled when outdoor air temperature network variable is received. Stand-by time and Stand-by setpoint parameters available only when VI- PIR cover is connected. COM Address and various other parameters when a communication module is integrated inside the unit. VI-PIR Viconics Passive Infrared Cover Thermostat shall be supplied with (or capable of being retrofitted on site) with the VI-PIR cover. Passive infrared sensor shall be integrated into the cover of the thermostat. Controls with remote motion detectors are not acceptable. VI-PIR shall add a third level of occupancy, Stand-by in between Occupied and Unoccupied. Thermostat shall have an adjustable Stand-by timer integrated to change the occupancy mode from Occupied to Stand-by if no motion is detected. Additionally, the thermostat shall drop from Stand-by mode to Unoccupied if no motion is detected for a certain amount of time during Stand-by mode. Both timers are adjustable. Stand-by mode shall have adjustable heating and cooling setpoints. Stand-by setpoints are intended to be set a few degrees less or more than Occupied setpoints to ensure a quick recovery to Occupied setpoints when motion is detected. Controls with motion detectors that only switch from Unoccupied mode to Occupied mode without a stand-by mode are not acceptable. Thermostats shall be Viconics, model VT7200x5x00x
