EasyTouch RV 354 Manual

Wiring the thermostat

Original thermostats can have a plug-in connector, or could be direct wired to the RV

manufacturers wiring. Thermostats wired with a plug can simply unplug the original plug and plug in the

EasyTouch RV thermostat.

Micro-Air provides a connector to directly wire these thermostats to the wiring if the

manufacturer has directly wired the thermostat. Match the original wiring colors to the provided

EasyTouch connector colors to install the thermostat. See Table 1 for details on the colors used with the

thermostat and the function of the wires.

Note: Some versions of this thermostat come with a connector wired to the EasyTouch circuit board.

Directly wired customers can cut off the connector to access the wires to make connections.

Note: See Appendix C: 8430-331 wiring for a different wiring table when replacing model number 8430-

331.
