Installation Overview
Removing the Old Thermostat
Pry open the thermostat using a small screwdriver on the visible seam on the bottom, top and sides. The display part will disconnect and allow the thermostat to be turned around to reveal the wiring connections. Take care not to pull out the wires as you remove them from the wall. The thermostat’s circuit board will remain attached to the front side of the thermostat. Take note of the three wires leading into the wall of the RV. Before removing the wiring, write down the color of the wire and the terminal to which each wire connects. We recommend taking a picture of the wiring before removal. GE’s wire terminals are labeled: GND, COMMS and +12V. Release each wire from its connection by unscrewing each small screw on the terminal block. Remove the wall attachment screws from the wall bracket forming the back half of the GE thermostat. Tape the wires to the wall to avoid losing them in the opening.
Using the push button terminals
Figure 1 shows a screwdriver depressing the push button connector. The silver gate is opened for the wire to be inserted. Releasing the button traps the wire and makes the connection. Remove
approximately 3/8 inch (1cm) of insulation from the wire to be inserted. Use a small screwdriver (not provided) or similar tool to push down on the square push button. Insert the wire in the insertion space and press the push button. Verify the connection by gently pulling on the wire. Do not force excessive wire down into the connector. If the stripped wire end is longer than 3/8 inch, cut the end so there is no bare wire sticking out when properly inserted.
Wiring the Micro-Air Thermostat
There are three terminals on the back of EasyTouch RV Model 347 labeled SIG, GND, and 12V. They will be connected to the push terminals on the back of the EasyTouch thermostat. Use the information you have written down determine the connections.
