If a switch box was not used, mount the
thermostat directly to the wall.
Feed the wiring through the openings in
the back of the thermostat.
Use screws in the screw holes to fasten the
thermostat to the wall. At least one of the
screws should enter a wall stud or similar
rigid material. •

Thermostat Wiring
The thermostat operates a single heating system zone together with a cooling
system and fan.
Power and communication are provided to the thermostat by connecting the tN2
terminals on the thermostat to the tN2 terminals on a tN2 Wiring Center, House Control,
Zone Manager or Expansion Module. tN2 terminals are not polarity sensitive.
Connect the Rc, Y and G terminals on the thermostat to the R, Y and G terminals
on the cooling equipment.
