Indicators
There are three colored lights on the left side of the thermostat:
•
PWR
(Green) – When this light is on, the unit is powered.
•
RUN
(Yellow) – When this light is on, the compressor is
running. If the light is flashing, the unit is currently in the five-
minute lockout.
•
SET
(Red) – This light flashes when the set-point
temperature is changed by pressing one of the three control
buttons (see below). It flashes once for each press of the
⇑
or
⇓
button, and twice when the
55
button is pressed.
When the unit is first turned on, all three lights flash slowly
while the thermostat starts up. Once the unit completes its
start-up check, the compressor is locked out for five minutes.
During this time the
RUN
light will be flashing slowly (1 flash
per second).
All three lights will flash rapidly if there is no probe connected
to the thermostat.
Buttons
To change the set-point temperature, press either the
⇑
or
⇓
button. The SET light will flash once for each 1°F the set-point
is changed. This set-point will remain in memory until you
change it.
If you forget where the unit is set, pressing the
55
button will
reset the set-point to 55°F and the SET light will flash twice.
The temperature cannot be adjusted below 50°F or above 76°F.
Attempting to set the unit outside this range will cause the
SET
light to rapidly flash.
Operation
Whenever the compressor shuts off normally, a five-minute
lockout period begins and the
RUN
light will be flashing slowly
(1 flash per second).
If the compressor runs for 90 continuous minutes, a five-
minute defrost cycle is forced, during which time the
compressor will not run. During this defrost cycle the
RUN
light
will be flashing rapidly (2.5 flashes per second).
