Page 4: Unit Protection Module (Upm)
Unit Protection Module (UPM) The Unit Protection Module (UPM) as shown in figure 1, is a printed circuit board (PCB) that interfaces with the thermostat or the digital direct controller. The main purpose of this device is to protect the compressors by monitoring the different states of switches and sensors, this device provides time delays and protects the unit against freezing of the water and refrigerant heat exchangers as well as condensate overflow when the appropriate sensors are installed. -
Page 5: Power Random Start Up
The anti short cycle delay is 300sec delay Power Random Start Up on break during normal operation. This feature prevents multiple units sharing same electrical circuit or network from NOTE: tarting at the same time. If the board is set to test mode through the “TEST” DIP switch the delay will be 5 seconds. - Page 6 High pressure protection Low pressure protection If the LPC switch is open upon a Y call the the HPC switch is open upon a Y call the UPM will not energize the CC output and UPM will not energize the CC output and therefore the compressor will remain off, the therefore the compressor will remain off, the fault LED will flash two (2) times for the LPC...
