Removing the Old Thermostat
The original thermostats have a front cover that pops off. Behind the cover there are 2-4 mounting
screws that must be removed to free the back plate. Once the thermostat is removed, pull out some of
the wire from the wall to inspect how it was installed.
Some RV builders will use the proper plugs recommended by the original thermostat
manufacturer, which is also how EasyTouch RV is designed. This means you can simply unplug the
thermostat and proceed to the next section.
Some RV builders do not use the proper plugs and direct wire the thermostat to the RV
manufacturers wiring using wire crimps or similar. If the unit is direct-wired then take some pictures of
this wiring for reference. Be sure that you can see where the thermostat wires meet with the wall wires
as they are typically different colors. You can also write in
later in the section to record what color
wires meet.
Wiring the Thermostat
Molex™ Plugs
If your installation was done with the proper mating Molex™ plugs, then you can simply plug in
all the mating connectors and move on to the section
. The provided wire 9-pin
wire harness will not be needed. Not all installations will use all plugs, just ensure that every original plug
has an EasyTouch match.
If the plugs are not the standard Molex™ plugs
that mate with EasyTouch then you will have to
wire it direct as described in the
section. You could also make up your own plugs
but is beyond what Micro-Air can assist with.
Direct-Wired - General
The original thermostat will have wires coming out of the back that are connected to the RV
manufacturer
’
s wiring harness, using a crimp-splice or similar. The wire colors on the RV manufacturer
’
s
harness can vary, but the wires at the back of the original thermostat are always the same color for their
use.
Follow the thermostat wires to where they are spliced to the RV
manufacturer’s
wire harness.
Write in the RV wiring harness colors in
below before making connections. Take pictures if you
have not already for reference as well. Some thermostats and harnesses may not have all of the wires
shown in
. The important part is that every original wire has an EasyTouch match.
