LAE CONTROL
SEQUENCE OF OPERATION
1. Cabinet is plugged in.
a. Display will illuminate.
b. Interior light will illuminate on glass door models only. (If lights do not come on please see
instructions on following page(s).) Solid door cabinet lights are controlled by door switch.
2. After the LAE control preprogrammed time delay of 3 minutes, the compressor and evaporator fan(s) will start if
the control is calling for cooling.
a. Control may be already pre-programmed from the factory so at the start of every compressor cycle or
during a defrost cycle, the condenser fan(s) will reverse for 30 seconds to blow dirt off the condensing
coil.
3. The LAE control will cycle the compressor but may also cycle evaporator fan(s) on and off determined by the
Set-Point and Differential temperatures. (If the Set-Point needs to be changed due to conditions please see
instructions on the following page(s).)
a. The Set-Point is the preprogrammed temperature which shuts off the compressor.
b. The Differential is the preprogrammed temperature that is added to the Set-Point temperature that will
start the compressor.
Example: If the Set-Point is -9°F/-23°C and the Differential is 10°F/5°C
(Set-Point) -9°F + 10 (Differential) = 1°F
Or
(Set-Point) -23°C + 5 (Differential) = -18°C
The compressor and evaporator fan(s) will cycle off -9°F/-23°C
and back on at 1°F/-18°C
4. The LAE control may be preprogrammed to initiate defrost by interval or at specic times of day. (If additional
Defrost Intervals or Cycles are needed or a Manual Defrost is required due to conditions please see instruc-
tions on the following page(s).)
a. At this time the “dEF” will appear on the display and compressor will turn off until a preprogrammed
temperature or duration is reached. During this time for freezers only, evaporator fan(s) will also
turn off and the coil heater and drain tube heaters will also be energized.
b. After the preprogrammed temperature or duration for defrost has been reached there may be a short
delay for both the compressor and evaporator fans to restart. At this time “dEF” may still appear
on the display for a short time.
True Manufacturing recommends that ONLY the Set-Point and/or
Defrost Interval may be adjusted due to certain conditions.
This sequence is NOT model specific.
If you have any questions, please contact the Technical Service Department.
