Battery Tip
The Master Thermostat must be hardwired (R and C terminals connected to 24 VAC). Batteries may be
used for clockbackup during power-outages, batteries are also recommended to simplify establishing
communication process. This allows the installer to take the master thermostat to each zone they
are connecting.
