Remove the Old Unit
Read the instructions carefully before removing any
wiring from the existing thermostat. Wires must be
labeled before they are removed. THERE IS NO
STANDARD COLOR CODE. When removing wires from
their terminals, ignore the color of the wires and LABEL
THEM by the terminal where they were screwed.
Switch OFF electricity to the furnace and air conditioner,
then follow these steps.
1.
Remove the cover from old thermostat. Most are snap-on types and
simply pull off. Some have locking screws on the side or front. These
must be loosened. DO NOT remove wires. Note the letters printed near
the terminals. Attach labels (enclosed) to each wire for identification.
2.
Label the wires one at a time. You must label all the wires before you
proceed. With all wires labeled,
remove them from the old unit.
3.
Make sure the wires do not fall back
inside the wall. You can wind them
around a pencil to keep them from
falling.
4.
Loosen all screws on the old
thermostat and remove it from the
wall.
