What to do if my Honeywell RTH6580WF Wi-Fi Thermostat display is blank?
If your Honeywell Thermostat display is blank, check the circuit breaker at the main panel. Also, ensure the ON/OFF selector is set to ON. If the problem persists, try resetting the switch using a paper clip.
Why are my Honeywell RTH6580WF Wi-Fi programs not running as expected?
If your Honeywell Thermostat programs aren't running as expected, first ensure that the switch is properly programmed. Note that - : - - indicates an inactive program. If your switch is configured for a 12-hour format, verify that PM appears on the left side of the screen when an afternoon time is displayed.
Why is my Honeywell RTH6580WF Wi-Fi Thermostat display faded or irregular?
A faded or irregular display on your Honeywell Thermostat might be due to the ambient temperature being below freezing point.
What to do if my Honeywell RTH6580WF Wi-Fi Thermostat resets when controlling a relay or contactor?
