XII. OPTIONAL ECONOMI$ER IV See Fig. 23 for EconoMi$er IV component locations. The optional EconoMi$er IV comes from the factory fully wired and assembled. No field wiring or assembly is required for standard outdoor dry bulb changeover operation. Field wiring of accessory sensors is required for different operational modes. A. EconoMi$er IV Standard Sensors Outdoor Air Temperature (OAT) Sensor The outdoor air temperature sensor (HH57AC074) is a 10 to 20 mA device used to measure the outdoor-air temperature. The outdoor-air temperature is used to determine when the EconoMi$er IV can be used for free cooling. The sensor is factory-installed on the EconoMi$er IV in the outdoor airstream. See Fig. 23. The operating range of temperature measurement is 40 to 100 F. Supply-Air Temperature (SAT) Sensor The supply-air temperature sensor is a 3 K thermistor located at the outlet of the indoor fan. See Fig. 24. This sen sor is factory installed. The operating range of temperature measurement is 0° to 158 F. The temperature sensor is a short probe with blue wires running to it. Outdoor Air Lockout Sensor The EconoMi$er IV is equipped with an ambient temperature lockout switch located in the outdoor airstream which is used to lock out the compressors below a 42 F ambient temperature. B. EconoMi$er IV Controller Wiring and Operational Modes Determine the EconoMi$er IV control mode before set up of the control. Some modes of operation may require different sensors. Refer to Table 28. The EconoMi$er IV is supplied from the factory with a supply-air temperature sensor and an outdoor air temperature sensor. This allows for operation of the EconoMi$er IV with outdoor air dry bulb changeover control. Additional accessories can be added to allow for different types of changeover control and operation of the EconoMi$er IV and unit. Outdoor Dry Bulb Changeover The standard controller is shipped from the factory configured for outdoor dry bulb changeover control. The outdoor air and supply-air temperature sensors are included as standard. For this control mode, the outdoor temperature is compared to an adjustable set point selected on the control. If the outdoor-air temperature is above the set point, the EconoMi$er IV will adjust the outdoor-air dampers to minimum position. If the outdoor-air temperature is below the set point, the position of the outdoor-air dampers will be controlled to provide free cooling using outdoor air. When in this mode, the LED next to the free cooling set point potentiometer will be on. The changeover temperature set point is controlled by the free cooling se...
