2.3) Removing your old thermostat
CAUTION: to avoid electric shock, turn off the
power of the heating/cooling system at the main
power box in your home. Read the following
instructions carefully before disconnecting the
wires.
1. Turn off your old thermostat.
2. Remove the cover from the old thermostat
You may have to pull extra hard.
3. Unscrew the old thermostat from the wall plate.
4. Now find the screws attaching the wall plate to
the wall, and remove them. You should now be
able to pull the wall plate a small distance from
the wall. Do not disconnect any wire yet,simply
locate the wires.
WARNING:
After removing the wall plate, if you find
that it is mounted on a junction box (e.g. a box
similar to one behind a light switch or electric
outlet), high voltage circuit may be present and
there is a danger of electric shock. Please consult a
qualified electrician.
2.4) Wire Labeling
1. Disconnect and identify each wire.
2. You may wish to tape the wires to the wall to
keep them from slipping through the hole in the
wall. If the hole in the wall is larger than
necessary, fill it in order to prevent hot or cold
air to penetrate the thermostat. In this manner,
the thermostat will behave perfectly.
