CONTROLLER OPERATION
The electronic controller is located in the
cas
sette 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 setpoint and differential
temperatures.
a. The setpoint 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 reflect the
refrigeration cycle of the setpoint and it’s
differential. The most accurate temperature on
a cabinets operation is to verify the product
temperature.
