A/C THERMOSTAT OVERVIEW
The Electronic De-icing Thermostat (EDT) is a micro
controller based module that measures evaporator coil
temperature and cycles the compressor clutch to
maintain a constant evaporator pressure.
NOTICE
The EDT has a six second delay before start up to
protect the compressor clutch.
The EDT will turn the clutch on when the evaporator coil
temperature is above 35.6°F (2°C). If the EDT does not
detect any malfunction, it will continue to operate and the
status LED will be lit continuously. When the evaporator
temperature is below 28.4°F (-2°C), the EDT will turn off
the clutch and status LED.
When the EDT detects an error from the temperature
sensor, the status LED will blink. Refer to the chart
below.
