INSTALLATION TIPS
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.
- Do not install thermostats in locations:
- Close to hot or cold air ducts
- That is in direct 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
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.
Getting to know your thermostat

- Glow in the Dark Light Button
- Fan Switch
- System Switch
- Easy Change Battery Door
- Setpoint Buttons
- User Buttons
Important
The low battery indicator is displayed when the AA battery power is low. If the user fails to replace the battery within 21 days, the screen
will only show the low battery indicator but maintain all functionality. If the user fails t replace the batteries after an additional 21 days (days 22-42 since the first “low battery” display) the set points will change to SS°F(Heating) and 8S°F(Cooling). If the user adjusts these setpoints away from these it will hold for 4 hours and then return to either SS°F or 8S0 F. After day 42 the batteries must be replaced immediately to avoid freezing or overheating because the thermostat will shut the unit off until the battery is changed.
Removing the private label badge
Gently slide a screwdriver into the bottom edge of the badge. Gently turn the screwdriver counter clockwise. The badge is held on by a
magnet in the well of the battery door. The badge should pry off easily. Magnet indoor t Does not use force.

- A Field-supplied jumper.
Typical 2H/1 C heat pump system
Typical 2H/1 C heat pump system with separate emergency heat
NOTE: In many systems with no emergency heat relay a jumper can be installed between E and W2.
Caution: Electrical Hazard Failure to disconnect the power before beginning to install this product can cause electrical shock or equipment damage.
Warning:
All components of the control system and the thermostat installation must conform to Class II circuits per the NEC Code.
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 green wire may not be connected to the G terminal.
- Loosen the terminal block screws. Insert wires then retighten terminal block screws.
- Place non-flammable insulation into the wall opening to prevent drafts.

MOUNT THERMOSTAT & BATTERY INSTALLATION
Mount Thermostat
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 recommended even if the thermostat is hardwired (C terminal connected). When the thermostat is hardwired and batteries are installed, the thermostat will activate a compressor delay of 5 minutes when the thermostat detects a power outage from the hardwired power supply.
Important
High-quality alkaline batteries are recommended. Rechargeable batteries or low-quality batteries do not guarantee a 1-year life span.
FEATURES AND SPECIFICATIONS
Filter Change Reminder
If your installing contractor has configured the thermostat to remind you when the air filter needs to be changed, you will see FILT in the
display when your air filter needs to be changed. FILT will be shown in the display after your system has run long enough to require an air
filter change. Resetting the filter change reminder: When the FILT reminder is displayed, you should change your air filter and reset the reminder by holding down the second button from the top left side of the thermostat for 3 seconds.
Understanding Thermostat Staging
Your thermostat will control two stages of heating. The thermostat will try to maintain your comfort setting using the first stage for energy efficiency. The second stage of heating will only be used if your thermostat cannot maintain your comfort setting using only one stage. When the second stage is used you will see +1 in the display.
