I need some help with medium temp controls and operation. The system I need help on is a walk in cooler. It has a remote bulb t-stat, liquid line solenoid, dual pressure control at condensing unit, and a time clock. It is wired so that the thermostat directly cycles the condensing unit off and on. Am I correct in thinking that the thermostat should control the liquid line solenoid, which in turn should pump the system down to the pressure setting of the low pressure control? I think that this unit is wired incorrectly!
