7 Things You Need to Know About Managing Your Thermostat


1. How much does my thermostat setting affect my heating bill?

In heating mode, reducing your thermostat setting by 1-degree Fahrenheit for eight hours can save about 1% on your heating bill. In cooling mode, each degree you set your thermostat above 75 degrees Fahrenheit can cut your cooling costs by about 5%.

2. Why is my thermostat screen off?

If you have power to your home but the thermostat screen is off, call the number on your thermostat immediately for assistance.

3. How does the Fan Auto/ ON switch work?

The FAN selection key has two positions: Auto and On. The Auto position will allow the system fan to operate whenever the heating or cooling system is turned on by the thermostat. The On position will turn the fan on to run continuously, regardless of whether the heating or cooling system is turned on by the thermostat or not. Leaving the fan in the on position in the a/c mode can cause high humidity inside. If your home has fresh air ventilation, turning the fan to the ON position would allow the fan to run constantly pulling outside air into the home while the a/c or furnace is not operating, causing high humidity inside. It is recommended to always be in the Auto setting.

4. Why is the “cool on” or “heat on” appearing on my thermostat screen?

The thermostat has a built-in 5- minute delay to protect your equipment. If “wait” is displayed on the screen or “cool on” is flashing— wait 5 minutes for the system to safely respond.

5. Why does the thermostat temperature not match the thermometer in my home?

Honeywell digital thermostats are designed to display the room temperature in a way similar to how people sense temperature. This means the thermostat takes into account not just the ambient air temperature but also the radiant temperature of objects in the room (i.e. wall and furniture).

6. How can I upgrade my thermostat?

7. What do I do if my heat or air is not working?

In a case where your heat is not working, switch your thermostat to emergency heat and call the number on your thermostat immediately for assistance. For more information and instructions, please refer to your user manual.
