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.
By connecting these two thermostats together in a parallel
fashion, and by passing the low voltage supply through the
Sensaphone (See Figure 1), you can remotely or locally decide
which thermostat is in control of your furnace.
It is recommended that the “away” thermostat be connected to the
OFF terminal while the “home” thermostat be connected to the
ON terminal of the Sensaphone. This way, it’s easy to understand
which state your furnace is in: ON = Home and OFF = Away. The
supply voltage from your furnace (typically the wire labeled R or
24VAC), should always be connected to the C (Common) terminal
on the CottageSitter.
Figure 1:Dual Thermostat Setup
Note: This is a typical configuration when using
standard single-zone heat/cool thermostats. For ease-
of-use it is recommended that both thermostats be the
same model. Note also that all thermostats may not
be compatible with the dual-thermostat wiring
diagram. Consult your heating/cooling professional
for installation assistance.
