Feed the wiring through the openings in
the back of the thermostat.
Use screws in the screw holes to fasten the

screws should enter a wall stud or similar
rigid material.

Zone Manager or Expansion Module. tN2 terminals are not polarity sensitive.
Connect the optional auxiliary sensor wires to the sensor terminals 3 and 4.
