The EasyTouch 354 model thermostats were
designed to directly replace Coleman™, Airxcel™
and RVP™
ZC thermostats. Original thermostats must have model numbers of 8330-331, 8330-335, or
8430-331 to be replaced by this thermostat. A typical example of this thermostat is shown in figure 1.
Note the single slide switch and mode/zone button specific to this model. If your thermostat is not listed
or as shown, please contact Micro-Air

thermostat you received is correct for your application.
Figure 1
Installing the thermostat
There are three steps to installing the thermostat. First remove your old thermostat. Next
disconnect and reconnect the wiring. Finally install the mounting pins to the wall and mount your new
thermostat.
Removing the old thermostat
The original thermostat is held to the wall
with a backing plate that extends about ¼” (6.3mm)
from the wall. There are two slots on the top of the
thermostat as shown in Figure 1. Place a small
screwdriver in the slot and twist the screw driver
while pulling gently out from the thermostat top.
After the first side pops loose, do the same with the second slot. Remove the screws from the mounting
plate and remove the plate and thermostat. Unplug the connector from the RV wiring harness. Note,
some thermostats are directly wired by the manufacturer. See the next section for further details.
