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 of each refrigerant circuit, 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: starting 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 LP1 or LP2 switches are open upon a If the HP1 or HP2 switches are open upon a Y1 or Y2 call (Could be Y1 or Y2 or both) Y1 or Y2 call the UPM will not energize the the UPM will not energize the CC1 or CC2 respective outputs...
