If the circuit is connected to an Uninterruptible Power Supply (UPS), the power connection keeps the pumps running to recirculate cooling water in the event of a power failure. Upon loss of power, all compressors and fans shut down. At the same time, the dual-power relay closes, putting the unit in heat mode, allowing the controller to keep the pumps running and also removes any call for cooling. On power restoration, the dual power relay opens. The unit returns to cooling mode and stages up com
