Optima 40 14
If a wall mounted switch or a wall mounted thermostat is desired, Archgard recommends that
the device be wired as shown in Fig 1. This will allow the original on/off rocker switch to be
used incase the device that is mounted to the wall is inoperable.
Note: Archgard Industries dose not manufacture, or sell any wall switch or wall thermostat, and
will not extend warranty to them.
