STANDARD THERMOSTAT WIRING CONNECTIONS
Connect the thermostat wires to the yellow wire harness, which is connected to
terminals C and T on the module. The yellow wire harness contains a 1500-ohm
resistor, which programs the module to operate the compressor at maximum RPM.
There is no polarity requirement.
STANDARD THERMOSTAT OPERATION
The thermostat is attached to the plate. The wires follow the refrigerant lines to the
compressor section. Protect these wires from cuts and chafe.
The BD thermostat is variable. Turning the knob fully counterclockwise turns the unit
"OFF". The fully clockwise setting is the coldest. The thermostat may be adjusted to
obtain any temperature desired in the cabinet and the thermostat may be calibrated
should the warmest setting be too cold.
To calibrate the thermostat remove the upper and lower screws on the stainless steel
cover. Carefully move the stainless steel thermostat cover to reveal the white plastic
cover, which is on the thermostat. Underneath the white plastic cover, locate the
calibration screw.
To lower box temperature, rotate this screw counter clockwise. One full revolution will
change the box temperature approximately 6 degrees F.
To raise the temperature in the box rotate the screw clockwise.
