AIR CONDITIONING
AC Installation
Warmboard thermostats offer single-stage air
conditioning. Connecting an AC system to WCS
is very similar to wiring a 24v thermostat from
an AC unit, just follow the steps below.
f
Remove the front cover from Warmsource-E
f
Locate terminal connection “AC1/Fan” on the
Smart Reset Controller (SRC)
f
Connect the wires from the AC unit to the terminal
block accordingly:
RC
: 24 volt power (red wire)
Y
: Cooling Call (yellow wire)
G
: Fan (green wire)
f
To activate the “Fan Only” feature, use a small jumper
wire between the two RC ports on the terminal block
f
Repeat for “AC2/Fan” if using air conditioning across
two cooling zones
Some AC solutions require their own proprietary
controls. In these instances, WCS thermostats
CANNOT
be used to control the cooling.
