 CellarPro Networkable Thermostat Upgrade
Overview
Cooling units with the Networkable Thermostat (“NT”) Upgrade are configured with a unit-
mounted temperature display that provides troubleshooting, operational safety controls
and defrost cycles. The upgrade also includes 10 feet of 18/5 thermostat wire, which must
be connected to a 24VAC Networkable Thermostat.
Compatible NTs
CellarPro has tested and approved the following NT brands/models:
 Ecobee4 Pro
 Nest
 Honeywell / Lyric T6
 Any other 24VAC HVAC Thermostat with power consumption less than 4VA
Installation Instructions
IMPORTANT: CONNECT THE TERMOSTAT WIRE TO THE NT BEFORE CONNECTING
POWER TO THE COOLING UNIT.
Install the cooling unit but DO NOT connect power the cooling unit. The temperature
display on the cooling must be blank, indicating no power is connected to the cooling unit.
It is now safe to connect the 18/5 thermostat wire to the NT.
If the NT does not have a remote sensor, the NT must be installed inside the cellar. It is
very important to locate the Thermostat in an area that gets good airflow, ideally in a
location near the air return to the cooling unit.
If the NT has a remote sensor option, it may be possible to locate the main Thermostat
outside the cellar, and the remote thermostat inside the cellar. Make sure to disable the
temperature input from the main Thermostat, and control the cellar using the remote
sensor. It is very important to locate the remote sensor in an area that gets good airflow,
ideally in a location near the air return to the cooling unit.
Connect the color-coded thermostat lead wire to the NT terminals as follows:
 Red wire to terminal “Rc” (24VAC Power Supply)
 Blue wire to terminal “C” (24VAC Common)
 Yellow wire to terminal “Y1” (cooling / compressor)
 Green wire to terminal “G” (cooling unit fan)
 The White wire in the 18/5 thermostat wire harness is not used.
If the Thermostat does not have the terminal markings listed, it will be necessary to
contact the Thermostat manufacturer to advise the correct terminal mapping.
