8.3.2 Dual Thermostat Control
When a three or four wire low voltage thermostat is used, it is
easy to connect the Sensaphone to your furnace with the addition
of a secondary thermostat. One thermostat is set to your preferred
“away” temperature and the other thermostat is set to your
preferred “home” temperature. With your Sensaphone 400, you
will be able to switch between these two thermostats using the
relay output.
Ideally, the “away” thermostat would be in your pump or furnace
room. Remember that your “away” thermostat will be the only
thermostat that keeps your cottage or cabin at minimal heat while
you are away. It should not be located near a window or where
direct sunlight might warm it, near a furnace radiator or vent, or
any heat source such as a pilot light.
The second thermostat, the one pre-set for your preferred
temperature when you arrive at your cottage or cabin, should be
located in your normal living space. This would likely be your
existing thermostat, already located in a suitable location by your
heating professional at the time your furnace was installed.
