Sensaphone® Model 1108 User’s Manual

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.
