ENERGY SAVINGS PERCENT OF HEATING COSTS YOU CAN SAVE SAVINGS FOR ONCE-A-DAY 10°F (5°C) DECREASE* You can save energy with this thermostat during the heating season by automatically lowering the temperature setting 5°F (3°C) to 10°F (5°C) at night. You can also save energy during the cooling season by automatically raising the temperature setting during the day before you leave for work or school.
TROUBLESHOOTING GUIDE CAUTION IMPORTANT Temporary protection delay protects compressor; the thermostat allows the compressor to remain off for five minutes before restarting. Operating At Too Low Of Outdoor Temperature May Cause Compressor Damage. Damage to compressor possible. Do not operate cooling if outdoor temperature is below 50°F (10°C). Refer to manufacturer recommendations.
Symptom Heating or cooling does not come on. Corrective Action Check that the heat setpoint is above room temperature or that the cool setpoint is below room temperature. Check that the system switch on the thermostat is set to HEAT or COOL. Check the system fuse or circuit breaker and replace or reset if necessary. Check power to the heating or cooling equipment. Temperature setting is too warm or too cool. Adjust the temperature by pressing either the or key.
