Wiring the thermostat
Original thermostats can have a plug-in connector, push button connector block, or be direct
wired to the RV manufacturers wiring. All EasyTouch versions of the 352 thermostats have the push
button connector block. 352C models (X03 and X04 extensions) have a connector pre-wired to the
connector block for those models that come with connectors.
The tables in each section below list the RVP/Airxcel/Coleman thermostat model numbers that
can be used with each thermostat installation type. If your thermostat is not listed, please contact
Micro-Air https://www.micro-air.com/SupportRequest to verify the thermostat you received is correct
for your application. Coleman model numbers can be found in your original user’s manual and on the
back side of the thermostat or the back of the mounting plate.
Connector models
These models are the easiest to install. Just disconnect the connector from the wiring harness
on the original thermostat and plug in the new thermostat. Connectors are keyed so you cannot mix the
connectors.
Push button wire insert models
These thermostats connect using push
terminals on the back of the thermostat. Examine
the original thermostat and notice the labels
printed are printed as shown in figure 2. These
labels correspond to the same labels on the
EasyTouch thermostat. It is recommended to
remove DC power when moving the wires from
one thermostat to the other. Touching some wires
together can trip a breaker or burn a fuse in the
RV DC power circuit powering the thermostat. We
also recommend taking a picture of the original
thermostat wiring order so you can verify the
connection order on the new thermostat.
