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.

To permanently ignore the schedule, press up or down until the desired temperature is displayed. Then, press the Hold button to maintain the new temperature indefinitely. The word Hold will appear on the screen.

Press the Run button if you wish to cancel either override and resume the schedule. The word Hold will disappear and the thermostat will be set to the temperature programmed for the current period. Also ensure that the heat - off - cool switch is set to the desired run mode.

Remember, after you set the desired setpoint and select your desired hold the thermostat will change back from displaying your setpoint to the room temperature. This is normal. Allow your heating or cooling system to reach your setpoint over time.

How do I keep Honeywell thermostat at constant temperature?

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.

What is the default temperature on a Honeywell thermostat?

The default thresholds for temperature are pre-set at 45°F or 7.5°C and at 100° F or 38°C and you may change the settings in the Lyric app. The default thresholds for humidity are pre-set at 20% and at 70% and you may change the settings in the Lyric app.
