The top and bottom valve can never be open at the same time. After initial startup whichever compartment
calls for cooling first, will have priority. Once the setpoint is achieved the other compartment will be
cooled if necessary.
When both compartments have reached setpoint and the compressor shuts off, the last bypass valve that
was open will remain open for four minutes. This is done to help the refrigerant pressures stabilize and
reduce hard starting of the compressor.
This unit can be put into a diagnostic mode.
1. Unplug unit
2. Install jumper on pins 9 and 10 on board.
3. Plug unit back in.
Based on the attached chart you can turn on and off each relay individually.
