Installation
Replacing Existing Thermostat
Most existing thermostats have three parts:
• The cover, which may snap or hinge over the existing thermostat.
• The electronics or body, which controls the existing system.
• The sub-base, where the wires attach through the wall to the existing system.
1. Always turn off power to the air conditioning and heating system prior to
removing existing thermostat.
2. Carefully remove the cover and electronics body from the old thermostat
sub-base. Depending on the brand, these parts may pull off or need to be
unscrewed. The old sub-base should remain wired and on the wall until
steps 4 and 5.
3. Label every old wire with the letter of the connection to which the wire is
attached. Example letters are R, M, Y, etc. Depending on the brand of the
old thermostat, your letters may be different.

4. After labeling the old wires, loosen each connection and remove them from
the old sub-base. Secure the wires to prevent them from slipping into the
opening in the wall.
5. Remove the old sub-base from the wall, again being careful that the wires
do not slip into the opening in the wall.
6. Use the chart on page 1 to determine the new thermostat connections.
As an example, if the old thermostat had a G or F connection, it goes to
G on the new thermostat. It may be helpful to use the chart by circling
(with a pencil or pen) the letter of each wire removed from the old thermostat.
