What to do if my Honeywell RTH6500WF 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 Thermostat 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 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 RTH6500WF Wi-Fi resets when controlling a relay or contactor?
If your Honeywell Thermostat resets when controlling an inductive load like a relay or contactor, the reset is likely caused by the load. Install a snubber (AC130-03) at each relay/contactor to resolve this issue.
