CONTROLLER OPERATION
The electronic controller is located in the
cassette compartment. The controller comes
factory set, and is ready for use. The front
grille must be removed in order to access this
control. When removing the grille for this
operation or for condenser cleaning, care must
be taken not to damage the display interface
cable. It may be unplugged during this task.
1. Plug the merchandiser plug into its receptacle.
a. The controller display will illuminate.
b. The interior light will illuminate.
2. After the control preprogrammed time delay
of up to 6 minutes, the compressor and
evaporator fan(s) will start if the control is
calling for cooling.
3. The control will cycle the compressor but
may also cycle evaporator fan(s) on and off
determined by the Set-Point and Differential
temperatures.
a. The Set-Point is the adjustable
preprogrammed temperature.
b. The Differential is the non-adjustable pre
programmed temperature.
c. The Control is designed to read and display
a cabinet temperature not a product
temperature.
This cabinet temperature may reect the
refrigeration cycle of the Set-Point and its’
Differential. The most accurate temperature
on a cabinets operation is to verify the product
temperature.
