Micro-Air EasyTouch 355 Touch Screen Thermostat User Manual
Wiring the thermostat
Original thermostats can have a plug-in connector or be direct wired to the RV manufacturer’s
wiring. Thermostats wired with a plug can simply unplug the original plug and plug in the EasyTouch
thermostat. Wired thermostats require the optional connector which can be ordered with the
thermostat or ordered separately.
To wire the connector models, match the original thermostat wiring colors to the connector
colors. Please note that manufacture wiring from the wall may not match the colors until it joins with
the wiring stub from the original thermostat. See Table 1 for details on the colors used with the
thermostat and the function of the wires.
Note: See Appendix C: 9430-334 wiring for a different wiring table when replacing model number 9430-
334.
