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.)18-5 thermostat wire (communication cable) must be run between the evapora-
tor unit and the condensing unit.
24V Wiring Connections (Evaporator Unit)
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 (red to red, green to green, and blue to blue). NOTE: The evaporator will not contain a
yellow wire. See the next step for more information on the yellow wire.
4. Connect one wire from the 18-5 thermostat wire to the low-voltage yellow wire (1). Then connect the other 18-5 wire to the
blue low-voltage wires (2). The other three wires will not be used.
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 airow.
NOTE: Ensure equal distance
after the t-tting for each
evaporator unit.
