16. THERMOSTAT INSTALLATION
16.1. WOOD ADD-ON ONLY
The add-on must be connected to a thermostat. You can use the one provided with the unit or use one that is already
installed in your home. The thermostat must be installed on an inside wall and located where it is not likely to be
affected by the draft coming from an air outlet. It must be installed at a minimum of 55 inches (140cm) above the floor.
It is recommended to connect the thermostat to the add-on with a seven or eight threads wire connecting terminals Rc,
Rh C, W, Y, G, O and B.
If the thermostat is using a dry contact (powered by batteries), it is not necessary to connect the C (common) terminal
to the thermostat. Refer to the electrical diagram.
If you want to provide power to the thermostat, note that the connections may differ depending on the thermostat:
Some thermostats need Rc and C while others require Rh and C (in this case, verify the need for a jumper between Rc
and Rh in the thermostat user manual). No jumper is required with the thermostat supplied with the add-on as the Rc
and Rh are already connected together. Also, some thermostats have only the letter R. In this case, R refers to Rh.
(Connect only one of the two terminals R if there is a jumper between Rc and Rh on the thermostat). Refer to the
wiring diagram.
