Installation
Replacing Existing Thermostat
Most 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, and 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 hole in
the wall.
5. Remove the old sub-base from the wall, again being careful that the wires do
not slip into the hole 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. Using a pencil and the chart below, circle the letter of each wire
removed from the old thermostat.

Installing New Thermostat
NOTE: When installing this thermostat in a new location, following a few simple
guidelines and the applicable building codes will give the best results. Install the
thermostat in a location that provides good airflow by avoiding areas behind doors,
near corners, air vents, direct sunlight or heat generating devices. The wiring must
conform to all building codes and ordinances as required by local and national code
authorities having jurisdiction for this installation.
1. Always turn off the power to the air conditioning and heating system prior to
installing this thermostat.
2. Locate the release latch on the bottom (not the back) of the thermostat. Press
the release latch in and separate the body from the sub-base of the thermostat.
3. Set the thermostat electronics and cover down on a clean surface. Place the
sub-base on the wall in the desired location.
4. Using the slotted mounting holes in the sub-base, mark the placement of the
mounting holes through the slots and onto the wall. Ensure the wires come out
of the wall into the center hole of the sub-base.
5. After verifying the drill will not damage items in the wall, use a 3/16 drill to
create the mounting holes. Gently tap the supplied plastic anchors into the
holes in the wall.
6. Place the thermostat sub-base against the wall in the desired location. Ensure
the thermostat is level, the wires are inserted in the opening, and the mounting
holes are aligned with the slots on the sub-base.
7. Fasten sub-base to wall using the supplied screws into the plastic wall anchors.
8. Connect wires to the quick wiring terminal blocks. Use the wiring diagram chart
to ensure the old and new connections are correct.
9. To prevent electrical shorts and potential damage to the thermostat, make sure
all wire connections are secure and not touching each other.
10. Ensure the cover is still installed on the body, and install them onto the
sub-base. To do so, use the mounting tabs on the top of the sub-base as a
guide hinge, and close up the thermostat case by pivoting the body and cover
closed. The latch on the bottom of the thermostat will click when the case is
properly closed.
11. Flip the front thermostat cover open and open the battery compartment door.
12. Locate the positive [+] ends of the batteries and match them with the positive
[+] terminals located in the battery compartment. Install the two new “AA”
alkaline batteries (supplied). Close battery compartment door.
13. Restore system power and proceed to Programming Installer Settings.

Description of Options
1. Selects the programming mode, either full 7 day or 5-2 day
(weekday-weekend) programming or non-programmable.
2. Enables or disables the ARM™ feature. During ARM™, room temperature is
recovered gradually by turning on the heating or cooling before the end of the
set back period. In a multi-stage configuration, room temperature is recovered
gradually by using only the first stage heating or cooling until the last 20
minutes, to minimize the use of the 2nd stage heating or cooling. The set
point temperature is changed to that of the upcoming comfort program
temperature. ARM™ does not operate when the unit is in the temporary or
permanent HOLD mode if the program is temporarily overridden or if
emergency heat is selected for multi-stage heat pumps. If the ARM™ feature
is disabled the thermostat will recover the set point temperature at the
programmed set point time after the setback period ends.

4. Selects between 1st stage gas or electric heat. This Installer Option is not
available with a heat pump system.
5. Selects between 2nd stage gas or electric heat. This Installer Option is only
available with a 2 stage heat pump system.
6. For heat pump units with an electric auxiliary stage, both the first and second
stages of heating will run when a call for second stage heat is made. For heat
pump units with a fossil fuel auxiliary stage, the first stage will be locked out
one minute after a second stage heat call, and the second stage will only
be used.
7.
During the COOL mode of normal operation the fan will stay on for 60 seconds
after the cooling system has satisfied the set point temperature and has
turned off the compressor. This allows the system to provide higher efficiency
during cooling operation.
8. This thermostat includes an automatic compressor protection feature to
avoid potential damage to the cooling system from short cycling. This thermostat
automatically provides a delay after turning off the cooling system output to
protect the compressor. This protection is also present in the heat
operation on single stage heat pump systems to protect the compressor. To
disable this feature, set this option to SSPOF (off).
9. This thermostat provides cold weather compressor protection by locking out
the compressor stage (1st stage) of heating for a period of time after a power
outage greater than 60 minutes. The lockout period is one hour less than the
outage time, up to a maximum of 12 hours. During that period of time, the
auxiliary heat stage will still be available to maintain the set point temperature.
The compressor lockout can be disabled by setting this option to OFF.
10. Select between turning the AC power interrupt warning off or on. During a
power loss, the thermostat will display an outage warning. The system clock
will continue to run, and all settings will be maintained until the outage period
is over. This Installer Option is only available when thermostat is installed as a
hardwired unit.
11. Selects preferred temperature scale of either ºF or ºC.
