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 to replace the batteries after an additional 21 days (days 22-42 since 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 then return to either SS° F or8S 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.
Caution:
When the battery icon appears replace your AA batteries immediately. Failure to do so may result in your heating & cooling system becoming inoperable.
Follow the steps below to set the current time:
Important:
You will see a TECH SET option after the MENU key is pressed.
This TECH SET key is for installer configuration and should NOT be changed unless you consult your Professional Heating and Air Conditioning Technician.
If your installing contractor has configured the thermostat to remind you when the air filter needs changed, you will see FILT in the display when your air filter needs 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.
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.
Warranty Registration:
Your new thermostat has a 5-year limited warranty. You must register your warranty within 60 days of installation. You can register your new thermostat in 2 ways.
