In case of difficulty

If you have difficulty with your thermostat, please try the following suggestions. Most problems can be corrected quickly and easily.

Display is blank

• Check circuit breaker and reset if necessary.
• Make sure power switch at heating & cooling system is on.
• Make sure furnace door is closed securely.

No response to key presses (or temperature will not change)

• Check to make sure the thermostat is not locked (see page 17).
• Make sure heating and cooling temperatures are set to acceptable ranges:
• Heat: 40° to 90°F (4.5° to 32°C)
• Cool: 50° to 99°F (10° to 37°C)

Backlight is dim

• If thermostat is AC powered, a dim display is normal. The backlight remains on at a low level, and brightens when a key is pressed.

Thermostat shows the calendar screen (year, date, & month) when the

power is restored

• This indicates that the coin cell battery has drained out. Replace the coin cell battery immediately.

18

Heating or cooling system does not respond

• Press SYSTEM to set system to Heat. Make sure the temperature is set higher than the Inside temperature.
• Press SYSTEM to set system to Cool. Make sure the temperature is set lower than the Inside temperature.
• Check circuit breaker and reset if necessary.
• Make sure power switch at heating & cooling system is on.
• Make sure furnace door is closed securely.
• If “Wait” is displayed, the compressor protection timer is on. Wait 5 minutes for the system to restart safely, without damaging the compressor.

Display shows Fan Auto and On or Auto and Circ at the same time

• This is normal operation. Auto indicates the thermostat is following the programmed fan setting. If Auto and On is shown, the fan is scheduled for “On” during this period (see page 7).
