Make sure your wires are labeled. This is necessary to determine which step-by-step
wiring diagram you should use. This may require you to find the 'other end' connection for
each wire on your heating or air conditioning equipment and read the label there.
If you have a Zoned Heating/Cooling system with multiple thermostats, please refer to our
website at www.ritetemp-thermostats.com for installation notes or call 1-888-515-2585.
Caution
Do not allow
wires to touch
each other or parts on unit.
Wires must be routed through
the hole in the back plate, below
the terminal block, or they will
hit parts on the cover.
The Wire Chart below will help you determine the terminal connections you will use
on your new thermostat. See chart section that applies to your heat/cool system.
