Mode of Operation
The thermostat is a programmable, manual or auto changeover, up to 3-stage heat (depending on your model) and up to
3-stage cool (depending on your model) thermostat. It functions with air conditioning, heat pumps, gas, oil, or electric heat
systems. The thermostat activates the heating appliance when the room temperature is below the set heat temperature (by the
differential temperature). When the call for heat has been satisfied, the outputs are turned off. With heat pumps, the thermostat
will not let the compressor come on for 4 minutes after it turns off to protect your compressor.
When the room temperature is greater than the set cool temperature (by the differential temperature), the cooling device is
activated. When the call for cooling has been satisfied, the outputs are turned off. The thermostat will not let the compressor
come on for 4 minutes after it turns off to protect your compressor.
The program schedule can be overridden by changing the set temperature ( or ). This puts the thermostat into a
temporary hold. To remove the temporary hold, press icon twice.
UP – Used to increase the time, set temperatures, and to adjust configuration settings.
DOWN – Used to decrease the time, set temperatures, and to adjust configuration settings.
MENU – Used to enter configuration, set the clock, lock the thermostat, or select viewing options.
CONFIG Sets up thermostat to work for specific systems.
CLOCK Set year, month, date, and time.
LOCK Allows you to lock the thermostat to prevent tampering.
VIEW Allows you to see the remote sensor temperatures, date, current schedule period, lock screen, filter
accumulated time, and show details (system status).
HUMIDITY (910193129 model only) Allows you to view the current relative humidity and change humidity setpoint (10% to 80%).
FAN – Used to select between AUTO, ON, and HOURLY fan operation.
MODE – Used to select between OFF, HEAT, COOL, and AUTO changeover modes.
HOME – Wakes thermostat, returns to home screen, and enters changes into memory.
SCHEDULE – Used to edit program schedule, turn program on and off, and set vacation return dates.
ALARM – The water source heat pump Microtech III unit alarm will be displayed notifying the occupant that
service may be required.

Important Safety Information
WARNING!: Always turn off power at the main power supply before installing, cleaning, or removing thermostat.
• This thermostat is for 24 VAC applications only; do not use on voltages over 30 VAC.
• Do not short across terminals of gas valve or system control to test operation; this will damage your thermostat and void your
warranty.
• All wiring must conform to local and national electrical and building codes.
• Do not use air conditioning when the outdoor temperature is below 50 degrees; this can damage your A/C system and cause
personal injuries.
• Use this thermostat only as described in this manual.
ELECTRICAL SHOCK HAZARD – Turn off power at the main service panel by removing the fuse or switching the
appropriate circuit breaker to OFF position before installing new thermostat.
IMPORTANT: Thermostat installation must conform to local and national building and electrical codes and ordinances.
Note: Mount the thermostat about five feet above the floor. Do not mount the thermostat on an outside wall, in direct
sunlight, behind a door, or in an area affected by a vent or duct.
1. Turn off power to heating & cooling system by removing the fuse or switching the appropriate circuit breaker off.
2. Put thermostat sub base against the wall where you plan to mount it (be sure wires will feed through the wire opening in
the sub base of the thermostat).
3. Mark the placement of the mounting holes.
To Install Thermostat
ELECTRICAL SHOCK HAZARD – Turn off power at the main service panel by removing the fuse or switching the
appropriate circuit breaker to OFF position before removing the existing thermostat.
To Remove Existing Thermostat
1. Turn off power to heating & cooling system by removing the fuse or switching the appropriate circuit breaker off.
2. Remove cover of old thermostat; this should expose the wires.
3. Label the existing wires with the enclosed wire labels before removing wires.
4. After labeling wires, remove wires from wire terminals.
5. Remove existing thermostat base from wall.
6. Refer to the following section for instructions on how to install this thermostat.
A – Alarm
C – 24 VAC common
DH – Dehumidification
G – Low speed fan
G2 – High speed fan

5
4. Set thermostat sub base and thermostat away from working area.
5. Using a 3/16” drill bit, drill holes in the places you have marked for mounting.
6. Use a hammer to tap supplied anchors in mounting holes.
7. Use supplied screws to mount thermostat sub base to wall (make sure thermostat wire is through hole).
8. Insert stripped, labeled wires in matching wire terminals. Tighten screws to secure wires.
CAUTION! : Be sure exposed portion of wires do not touch other wires.
9. Gently tug wire to be sure of proper connection. Double check that each wire is connected to the proper terminal.
10. Snap thermostat onto the sub base.
11. Turn on power to the system at the main service panel.
12. Configure thermostat to match the type of system you have.
13. Test thermostat operation as described in “Testing the Thermostat”.

Remote Sensor Installation (Optional)
Terminals S1 and SC are used with a remote sensor. S1 can be used with a remote sensor to
monitor indoor temperatures. An indoor remote sensor is used to read the indoor temperature
in a different location. This is beneficial when the thermostat is not mounted in the ideal
location.
1. Remove cover from remote sensor housing.
2. Select an appropriate location for mounting the remote sensor.
3. Mount the remote sensor using hardware provided.
4. Install two-strand shielded wire between the S1 terminal on the remote sensor and the S1
terminal on the thermostat.
5. From the remote sensor, install a two-strand shielded wire from the common to the SC
terminal on the thermostat.
6. Configure the thermostat to work with the remote sensor.

Configuration and Thermostat Lock
During Configuration Mode, certain settings are protected by a
numeric code access screen to prevent unintentional changes that
could potentially damage the system or create a dangerous condition.
Whenever changes are attempted to one of the
critical settings, the unlock code screen will appear:
The unlock code for these critical settings can be found during the
power-up sequence.
The large number (indicated by “98” in the diagram) is the code that
will unlock the desired configuration setting.
The smaller numbers (indicated by “93” and “82” in the diagram) are
codes used to lock and unlock your thermostat to prevent tampering.
To view the default codes for your thermostat, remove the thermostat from the sub base
for 10 seconds. Reinstalling thermostat will cause the codes to display for approximately 5 seconds.
