Why can't I change the temperature on my Honeywell thermostat?
When Honeywell thermostat not reaching set temperature happens, reboot the thermostat. Turn off power to the thermostat for ten to twenty seconds. Then turn it back on. This is easy with many smart models because they can detach from furnace power.
How do I manually override my Honeywell thermostat?
Press up or down to immediately adjust the temperature. This will temporarily override the temperature setting for the current time period. “Temporary” will appear on the display and the current program period will flash. The new temperature will be used until the next period begins.
