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 three 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.

Installing New Thermostat

Quick Reference

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 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.

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. Because this thermostat has 14 possible connection points, you
may need to apply moderate force to separate the parts.
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 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.Locate the thermostat body, and ensure the cover is still installed properly.
Using the mounting tabs on the top of the sub-base as a guide or hinge, 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. Because
this thermostat has 14 possible connection points, you may need to apply
moderate force to close the case.

alkaline batteries (supplied). Close battery compartment door.
13. Restore system power and proceed to programming and system checkout.
