The EasyTouch 359 model 12-volt thermostats were designed to directly replace Dometic™ model
3106995 single zone DC 7.5-volt thermostats. The thermostats can be used in other applications with
certain electrical limitations as explained later in this document.
Safety First
Turn off power to the air conditioner breaker and to the 12-volt circuit powering the thermostat.
There is always a risk of shock in any system that is connected to high voltage utility power so removing
power greatly reduces that risk.
There is a risk of creating a short circuit with some of the thermostat wires during installation that
can cause a failure or undesired operation. Removing power reduces the risk you will damage something
or open a hard-to-find fuse during installation.
Installing the thermostat
There are four steps to installing the thermostat. Removing the thermostat, wiring the new
thermostat, installing the new thermostat, and finally, updating the control box wiring. Please read each
section entirely before proceeding with that section. Please perform these steps in order otherwise you
may damage your original thermostat.
Removing the old thermostat
IMPORTANT: Take a picture of the wires and labeling so if there are any questions about the original
configuration later, you can see how it was connected.
colors may be different from the normal factory suggested wire colors and not all wires may be used.
Label any that are not there with “Not used”.

Disconnect the red or red/white wire labeled +7.5V and place a piece of tape around the exposed
wire end. Disconnect the remaining wires (tape is not necessary). Remove the cover to expose the two
screws that hold the thermostat to the wall and remove the rest of the thermostat.

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 release 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.
