Page 44: Operation
5703827-XIM-A-0319 Operation Compressor operation Compressor operation details include: a. Compressors are controlled by the Y1 through Y2 thermostat inputs. If the Lead/Lag function is turned OFF, a Y1 input energizes the C1 output when the compressor number 1 anti-short cycle delay is at 0 and all refrigerant safety devices are closed (default 5 minutes). -
Page 45: Dry Bulb Changeover
5703827-XIM-A-0319 Dry bulb changeover For dry bulb economizer operation, the outside air is suitable for free cooling if the outside air temperature is 1°F below the economizer OAT enable setpoint and 1°F below the return air temperature. Free cooling is no longer available if the outside air temperature rises above either the economizer OAT enable setpoint or the return air temperature. -
Page 46: Power Exhaust
5703827-XIM-A-0319 If at any time the economizer output goes above the minimum position, the timer stops and resets when the economizer output returns to minimum position. If the demand for cooling from the space/return is satisfied, the economizer output modulates to the minimum position and the compressor outputs are de-energized as long as their minimum run timers have expired. -
