Test Mode when unit is running
When the unit is Switched ON and running, you can see which relays are ON or OFF and
the temperature of each sensor.
In this example:
The Compressor 1 and Fan 2 is running.
The Defrost heater 2, Door heater 1, Light 1 and Light 2 are ON
Door 1 is open, that is why Fan 1 is OFF and Light 1 and 2 is ON
(Fan stops when door is open.)
