2-DEFROST / TEMP CKT

 

This is a read-only menu. This screen shows the current operational status of Defrost Circuits and associated temperatures as provided by Auxiliary inputs.

NAME gives a description of the case loads for this defrost circuit.

STATUS indicates whether the defrost circuit is in defrost (DEFR), refrigeration (REFR), or a Manually Forced condition (F-DEFR, F-REFR).

TEMP-CTRLindicates whether temperature control is available for this circuit. This control feature allows the refrigeration solenoid to be operated ON and OFF to maintain a temperature setpoint.

AUX #X provides the actual temperature reading of the circuit. Note that X will be a number between 1 and 8 depending upon the Temp/Circuit number you are currently accessing.

REFRIG is the status of the defrost/refrigeration relay. ON indicates that power is being fed to the solenoid. OFF indicates that the solenoid is de- energized.

REF is an internal setpoint used by the Temp Control algorithm. This number will increase up / decrease down dependent upon the relationship of the temperature reading (AUX #) and the circuit setpoint.

Press ENT to view additional circuit information.

Note: Temperature Control is available on Hand Held Devices V2.40 or greater.
