A trained, experienced technician must install this product.
Carefully read these instructions. You could damage this product or cause a hazardous condition if you fail to follow these instructions.
Wall Locations
The thermostat should be installed approximately 4 to 5 feet above the floor. Select an area with average temperature and good air circulation.
Installation Tip
Pick an installation location that is easy for the user to access. The
temperature of the location should be representative of the building.
Do not install thermostat in locations:
- Close to hot or cold air ducts
- That are indirect sunlight
- With an outside wall behind the thermostat
- In areas that do not require conditioning
- Where there are dead spots or drafts (in corners or behind doors)
- Where there might be concealed chimneys or pipes
Subbase Installation
- Horizontal Mount
- Vertical Mount
For vertical mount put one screw on the top and one screw on the bottom.
For horizontal mount put one screw on the left and one screw on the right.
Installation Tip: Electrical Hazard
Failure to disconnect the power before beginning to install this product can
cause electrical shock or equipment damage.
Mercury Notice
All of our products are mercury free.
However, if the product you are replacing contains mercury, dispose of it
properly. Your local waste management authority can give you instructions on
recycling and proper disposal.
Mount Thermostate
Align the 4 tabs on the subbase with corresponding slots on the back of the thermostat, then push gently until the thermostat snaps in place.
Battery Installation
Battery installation is optional if thermostat is hardwired (R and C terminal connected to 24V power).
Important:
High quality alkaline batteries are recommended. Rechargeable batteries or low
quality batteries do not guarantee a 1-year life span.
Insert 2 AAA alkaline batteries (included) High quality alkaline batteries are recommended.
Thermostat Quick Reference

- Fan Switch
- System Switch
- Setpoint Buttons
Wiring
- If you are replacing a thermostat, make note of the terminal connections on the thermostat that is being replaced. In some cases the wiring connections will not be color coded. For example, the red wire may not be connected to the R terminal.
- Loosen the terminal block screws. Insert wires then retighten terminal block screws.
Installation Tip
Do not overtighten terminal block screws, as this can damage the terminal
block. A damaged terminal block can keep the thermostat from fitting on
thesubbase correctly or cause system operation issues.

This thermostat is shipped from the factory to operate a conventional heating and cooling system. This thermostat will also operate a heat pump system. See the “heat pump” configuration step on page 10 of this manual to configure the thermostat for heat pump applications.
Wiring Tips
Caution:
Electrical Hazard disconnect the power before beginning to install this
product can cause electrical shock or equipment damage.
C Terminal
The C (common wire) terminal does not have to be connected when the thermostat
is powered by batteries.
Warning:
All components of the control system and the thermostat installation must
conform to Class II circuits per the NEC Code.
Wire Specifications Use shielded or non-shielded 18-22 gauge thermostat wire.
Note:
“I. When connecting the thermostat to a PTAC, refer to the PTAC manufacturer
instructions to enable remote thermostat operation.
Wiring Diagrams
Power supply
Jumper (not supplied) to connect GL and GH terminals.
The Aux Heat Relay is energized as the second stage of heat.
Typical 1H/lCSystem: 2 Speed Fan
Typical 1H/lCSystem: 1 Speed Fan
Typical 1H/lC heat pump System: 1 Speed Fan
Typical 2H/lC heat pump System: 2 Speed Fan
Note: Most PTAC systems support two speed fan operation. In a single speed fan PTAC system or conventional single speed fan system, a jumper should be installed between GL and GH on the thermostat.
Technician Setup
Fan Operation Setup
Electric: The thermostat operation jumper pin should be put in the ELEC position. This setting allows the thermostat to operate the fan during a call for heat. Most PTAC systems will require ELEC Fan Operation Setup.
Gas: For systems that control the fan during a call for heat, put the jumper pin into the GAS position.
Technician Setup Menu
- Set the thermostat system switch to OFF.
- To enter Tech Setup Menu,press and hold “*”and “-“together for 3 seconds.
- Use “*”and“-”to select desired setting for each option.
- Tap “*”and “-“together to move next option.
- To exit Tech Setup Menu,move system switch or wait for 15 seconds.
Tech Setup Steps| LCD will show| Adjustment options|
Default
---|---|---|---
Room Temperature Calibration| This feature allows the installer to change the
calibration of the room temperature display. For example, if the thermostat
reads 70° and you would like it to read 72′ then select +2.| | You can adjust
the room temperature display to read up to 4* above or below the factory
calibrated reading.|
F or C| Select for Fahrenheit temperature read out select C for Celsius read
out.| | F for Fahrenheit C for Celsius
|
Compressor Short cycle delay| The compressor short cycle delay protects the compressor from short cycling. This feature will not allow the compressor to be turned on for 5 minutes after it was last turned off.|
| Selecting ON will not allow the compressor to be turned on for 5 minutes
after the last time the compressor was switched off. Select OFF to remove this
delay.|
Heat pump| When turned on the thermostat will operate a heat pump.Y will be
the first stage of heat & cool, W will be the second stage of heat.|
| OFF configures the thermostat for non heat pump systems. ON configures the thermostat for heat pump systems.|
Heating temperature setpoint limit| This feature allows you to set a maximum heat setpoint value.The setpoint temperature cannot be raised above this value.|
| 44.0 – 90.0 F
7.0 – 32.0 C|
Cooling temperature setpoint limit| This feature allows you to set a minimum
cool setpoint valve. The setpoint temperature cannot be lowered below this
value| | 44.0 – 90.0 F
7.0 – 32.0 C|
- Set the thermostat system switch to the desired position (COOL or HEAT).
- Press and hold “+”and “-”together for 3 seconds.
- Use “+”and “-” to adjust desired swing setting (The display reads in tenths of a degree.)
- To exit,move system switch or wait for 1 seconds
Swing Settings| LCD will show| |
---|---|---|---
Cooling swing (system cool)| The swing setting, often called”cycle rate”,
“differential” or “anticipation” is adjustable. A smaller swing setting will
cause more frequent cycles and a larger swing setting will cause fewer
cycles.|
| The cooling swing setting is adjustable from 0.2° to 2°. For example: A swing setting of 0.5° will turn the cooling on at approximately 0.5° above the setpoint and turn the cooling off at approximately 0.5° below the setpoint|
Heating swing (system heat)| The swing setting, often called”cycle rate”, “differential or “anticipation” is adjustable. A smaller swing setting will cause more frequent cycles and a larger swing setting will cause fewer cycles| | The heating swing setting is adjustable from 0.2° to 2°. For example: A swing setting of 0.5° will turn the heating on at approximately 0.5° below the setpoint and turn the heating off at approximately 0.5° above the setpoint.|
Swing Setting
The second stage of Heat will turn on at 2x the swing setting. The second stage will turn off when 1x the swing is reached. For example, if the swing setting is 0.8″ for heating and the thermostat is set at 70” F, the first stage will turn on at approximately 69.2° F. The second stage will turn on at 68.4°F and the first will turn off at 70.8” F
