DANFOSS ELECTRONIC TEMPERATURE CONTROL
GENERAL SEQUENCE OF OPERATION
YOUR TRUE GLASS & PLATE CHILLER MAY USE
AN ELECTRONIC CONTROL - 115V/60HZ ONLY
IF YOUR CABINET IS PRODUCED WITH AN ELECTRONIC CONTROL, THERE MAY BE
UP TO A 20 MINUTE DELAY WHEN CABINET IS PLUGGED IN.
If the serial number on your cabinet is higher than listed below, it was produced with
an electronic control.
1. Cabinet is plugged in.
a. Interior lights will illuminate of Glass Door Models only. If lights do not come on verify the light switch is in the
“ON” position. Solid door cabinet may or may not have lights that may be controlled by the door switch.
b. Cabinet will start in a Defrost Cycle.
2. During the initial Defrost Cycle, the evaporator fan(s) and the compressor will remain off for a minimum of 4
minutes.
a. After the Defrost Cycle there will be a 2 minute delay.
b. After the 2 minute delay the compressor will start.
c. The evaporator fans will remain off for an additional 3 minutes.
3. The Danfoss control will cycle the compressor and the evaporator fan(s) on and off together.
a. The temperature control is sensing the discharge air temperature.
b. The temperature control should be set on the #4 or #5.
c. The warmest setting is #1 and #0 is the off position.
d. The thermometer is designed to read and display a cabinet temperature not a product temperature. This cabinet
temperature may reflect the refrigeration cycle determined by the temperature control. The most accurate
temperature on a cabinets operation is to verify the product temperature.
4. The Danfoss control is preprogrammed to initiate defrost every 4 hours of compressor run time.
a. At this time the compressor and evaporator fan(s) will turn off and the evaporator coil heater and drain tube
heater will be energized. Some cabinets may also change the rotation of the reversing condenser fan motor.
b. Once a preprogrammed temperature of the evaporator coil is reached, the Defrost Cycle will terminate and the 2
minute delay will occur.
