WARNING
Important Safety Information
• Always turn off power to the air conditioning or heating system prior to
installing, removing, cleaning or servicing thermostat.
• This thermostat is a dual power thermostat and either requires 24 Volt
AC Power or two (2) properly installed "AA" Alkaline batteries for normal
operation and control of the heating or cooling system.
• Properly installed batteries will allow the thermostat to retain clock settings
in the event of loss of AC Power due to power outage or rolling
blackouts when used as a hardwired thermostat.
• This thermostat should only be used as described in this manual. Any other
use is not recommended and will void the warranty.

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
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 below 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.
NOTE: This thermostat is designed for use on low voltage 24 volt AC single stage
or multi-stage systems, including heat pumps with up to two stages of heating
and two stages of cooling. Do not use this thermostat on systems with voltage
higher than 30 Volts AC. This thermostat requires a transformer common wire for
proper installation if used as a hardwired thermostat.
