Typically the second stage will come on sooner in more severe weather, while in milder weather it will take longer. There is no adjustment to this feature, as it is designed to maximize both comfort and efficiency.

!CAUTION
If the outside temperature is below 50°F, disconnect power to the cooling system before programming. Energizing the air conditioner compressor during cold weather may cause personal injury or property damage.

TROUBLESHOOTING
If your thermostat’s display is frozen or displaying incorrectly, the thermostat may have been affected by static discharge or voltage variations. If this happens, press the RESET button (see fig. 2, page 2 for the location of the button). Pressing the RESET button will clear all user programming. The thermostat will revert to factory preprogramming. You will need to reset the time and, if desired, reprogram the thermostat to your selected program. If pressing the RESET button does not correct the problem, contact a qualified service technician.
For optimum performance, we recommend replacing batteries once a year with fresh “AA” Energizer® alkaline batteries.
