60 Variable Air Volume (VAV) Unit Controller Operation - Variable Air Volume Cooling and Constant Volume Heating Standard AAON VAV controls for standard and heat pump systems. During the cooling mode of operation the supply fan modulates based on the supply air duct static pressure and cooling modulates based on the supply air temperature. During the heating mode of operation the supply fan provides constant airflow and heating modulates based on the controlling temperature. Factory provided VFDs or ECM driven motors are used to vary the speed of the supply fans and thus vary the amount of supply air. Because of the reduced speed, VAV units can be very energy efficient at part load conditions. VAV units can be used to serve multiple spaces with diverse or changing heating and cooling requirements, with only a single unit being required for multiple zones. AAON VAV units can also be applied to a single zone. Space temperature sensor included with WattMaster controller is used for supply air temperature setpoint reset and unoccupied override. See Control Venders section for WattMaster, JENEsys, and Mini Controller specifics. Required Features Feature 2 - Hot Gas Bypass - Units without variable capacity scroll compressors.

61 Constant Volume (CV/CAV) Unit Controller Operation - Constant Volume Cooling and Constant Volume Heating Standard AAON Constant Volume controls for standard systems. During the cooling mode of operation the supply fan provides constant airflow and mechanical cooling modulates based on the controlling temperature. During the heating mode of operation the supply fan provides constant airflow and heating modulates based on the controlling temperature. A Constant Volume unit can be used to serve spaces with uniform heating and cooling requirements. Multiple units may be required for multiple zones. Space or supply air temperature sensor can be used as the controlling sensor. If supply air temperature is not used as the controlling sensor it is used as a temperature lockout. If supply air temperature sensor is used as the controlling sensor, space temperature sensor is used for supply air temperature setpoint reset and unoccupied override.

During the cooling mode of operation the supply fan provides constant airflow and mechanical cooling modulates based on the controlling temperature. During the heating mode of operation the supply fan provides constant airflow and heating modulates based on the controlling temperature. Make Up Air units are designed to provide 100% outside air to the system for ventilation purposes. Make Up Air units can improve indoor air quality (IAQ) and also be used to positively pressurize to the space. See Control Venders section for WattMaster, JENEsys, and Mini Controller specifics.

63 Single Zone Variable Air Volume (Single Zone VAV) Unit Controller Operation - Variable Air Volume Cooling and Constant Volume or Variable Air Volume Heating Standard AAON Single Zone VAV controls for standard and heat pump systems. During the cooling mode of operation the supply fan modulates based on the space temperature and cooling modulates based on the supply air temperature. For constant volume heating, during the heating mode of operation the supply fan provides constant airflow and heating modulates based on the controlling temperature. For variable air volume heating, the supply fan modulates based on the space temperature and heating modulates based on the supply air temperature. Factory provided VFDs or ECM driven motors are used to vary the speed of the supply fans and vary the amount of supply air. Because of the reduced speed, single zone VAV units can be very energy efficient at part load conditions. Single zone VAV units can be used to serve a single space or multiple zones with uniform heating and cooling requirements.

66 AAON Mini Controller Figure 8 - Remote Mounted AAON Mini Controller The AAON Mini Controller is a simple controls option for energy saving applications. It is remote mounted in the space similar to a conventional thermostat. Controllable Features A lead/single variable capacity scroll compressor (with up to two total compressor stages), air conditioner or heat pump configuration, ECM driven/vfd controlled variable speed supply fan, sensible or enthalpy controlled economizer and modulating gas/scr electric heating are controllable with the AAON Mini Controller. Modulating hot gas reheat is available with a space temperature sensor and space relative humidity sensor version of the controller. Push button override, alarms and trend logging are available directly from the controller. Applications The controller can be used for constant volume air conditioner and heat pump applications or single zone VAV air conditioner and heat pump applications. Scheduling Weekday, weekend, entire week or daily scheduling is available with the AAON Mini Controller. Twelve days of holiday scheduling are also available. Networking The AAON Mini Controller can be directly connected to a BACnet MSTP network through an EIA-485 connection. The MAC Address, Baud Rate and Max Master are configurable. Security The AAON Mini Controller includes password protected User, Operator and Administrator profiles for configuration, scheduling and setpoint adjustment levels of control. Required Options The AAON Mini Controller is available for AAON split systems with a variable capacity scroll compressor. 1-2 stages of heat are available with an air conditioner and 1 stage of emergency heat is available with a heat pump. The controller has a limited quantity of inputs and outputs and thus the quantity of features which can be controlled and are available in AAONEcat32 are limited. 66

67 Electrical Service Sizing Data Use the following equations to size the electrical service wiring and disconnect switch for the unit. Electrical data for a specific unit configuration can be found with the AAONEcat32 software. For further assistance in determining the electrical ratings, contact the Applications Department, or consult U.L The Minimum Circuit Ampacity (MCA) and Maximum Overcurrent Protection (MOP) must be calculated for all modes of operation which include the cooling mode of operation, the heating mode of operation, and if the unit is a heat pump the emergency heating mode of operation and auxiliary heating mode of operation. The emergency or backup heating mode of operation is when the secondary heater is in operation and heat pump or compressor heating is not in operation. The auxiliary or supplemental heating mode of operation is when heat pump or compressor heating is in operation and the secondary heater is also in operation. To calculate the MCA and MOP, the number of motors and other current drawing devices in operation must be known for each mode of operation. The largest MCA and MOP values calculated from all the modes operation are the correct values and are also on the unit nameplate. For example, during the cooling mode of operation of an air-cooled DX unit or an air-source heat pump the supply fans, compressors, and condenser fans are all in operation. During the heating mode of operation of an air-cooled DX unit or the emergency heating mode of operation of an air-source heat pump only the supply fans and heater are in operation. During the auxiliary heating mode of operation of an air-source heat pump the supply fans, compressors, condenser fans, and secondary heater are all in operation. Once it is determined what current drawing devices are operating during each mode of operation use the equations shown below to calculate the MCA and MOP. Use Rated Load Amps (RLA) for compressors and Full Load Amps (FLA) for all other motors and electric heaters. Load 1 = Current of the largest motor/compressor in operation Load 2 = Sum of the currents of the remaining motors/compressors in operation Load 3 = Current of electric heaters in operation Load 4 = Any remaining loads greater than or equal to 1 amp Single Phase Electric Heat FLA Calculation Three Phase FLA = ( Heating Element kw ) x1000 Rated Voltage FLA = ( Heating Element kw ) x1000 ( Rated Voltage) x 3 67

69 Electrical Service Sizing Data Continued Fuse Selection Select a fuse rating equal to the MOP value. If the MOP does not equal a standard fuse rating select the next lower standard fuse rating. If the MOP is less than the MCA then select the fuse rating equal to or greater than the MCA. The standard ampere ratings for fuses, from the NEC Handbook, 240-6, shall be considered 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 125, 150, 175, 200, 225, 250, 300, 350, 400, 450, 500, 600, 700, 800 and 1000 amperes. Disconnect (Power) Switch Size DSS MOP Select the standard switch size equal to the calculated MOP value. If this value is not a standard size, select the next larger size. 69
