During normal operation, the second stage of heat or cool may
take 15 to 30 minutes to turn on. The delay varies depending on
the performance of the first stage. 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.
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.
