24V WIRING CONNECTIONS (EVAPORATOR UNIT)
The 24V Thermostat Conversion Kit requires a standard 18-5 thermostat wire to be run from the evaporator unit to the
thermostat. The white wire will not be used, as there is no heating function. (Some thermostats need a common wire and some
do not; the unit is equipped with a common wire if needed.)
If the system is equipped with the Cold Weather Start Kit a standard 18-2 thermostat wire must be run between the evaporator
unit and the condensing unit.
24V Wiring Connections (Evaporator)
1.
Route a standard 18-5 thermostat wire into the evaporator unit.
2.
Locate the wire thermostat connection cable inside of the evaporator unit.
3.
Connect the wires according to color (yellow to yellow, red to red, green to green, and blue to blue).
4.
If the system is equipped with a Cold Weather Start Kit, connect one wire from the 18-2 thermostat wire to the low-voltage
yellow wires (2). Then connect the other 18-2 wire to the blue low-voltage wires (2).
Thermostat Wiring Connections
Follow the thermostat installation instructions.
NOTE:
The white wire will not be used, as there is no heating
function.

NOTE:
To ensure correct system operation, the
24V thermostat must be placed inside the
wine cellar, preferably in a central location
away from any airflow.
Cold Weather Start Kit Wiring Connections
If the system is equipped with a cold weather start
kit, connect one of the 18-2 thermostat wires to the
purple #12 wire. Connect the other 18-2 wire to the
grey #13 wire.
