Q: What are the fan modes on a Honeywell thermostat?

Auto : Fan runs only when the heating or cooling system is active. On : Fan runs continuously. Circ : Fan runs randomly about 33% of the time to circulate air.

Q: What is the "fan mode" used for on a Honeywell thermostat?

Fan mode controls how the fan operates: Auto : Runs only during heating or cooling cycles. On : Keeps the fan running continuously. Circ : Runs the fan periodically to maintain air circulation

Special function

Auxiliary heat control (Setup Function 26)

Comfort Setting: The thermostat will prioritize comfort over economy depending on heat pump performance, load conditions, and whether the thermostat is calling for the heat pump. Raising the temperature just a few degrees will often activate the auxiliary heat.
Economy Setting: The thermostat will attempt to reach the temperature setting without activating the auxiliary heat. The thermostat will wait to activate the auxiliary heat depending on heat pump performance, load conditions, and how many degrees the temperature setting is changed.

Honeywell FocusPRO 5000 Heating-Cooling Thermostat-FAQs

How does the Honeywell thermostat measure temperature?

Honeywell thermostats consider both the air temperature and radiant temperature from objects like walls and furniture to provide a more accurate reading, similar to how people sense temperature.

How do I set the heat on my Honeywell thermostat?

To set the heat, toggle the system switch to “Heat,” then use the arrow buttons to adjust the temperature to your desired level.

How do I turn off my Honeywell thermostat?

Slide the system switch (labeled Heat-Off-Cool) to “Off.” You can also adjust the temperature manually or set a schedule for heating and cooling.

What is the PIN for a Honeywell thermostat?

The PIN can be found by flipping the thermostat over and locating the 4-digit number on the side with the batteries. Add 1234 to that number to get the thermostat’s PIN.

How does a thermostat detect temperature?

Thermostats use an internal sensor that measures temperature via infrared radiation. This radiation is converted into electrical signals to provide an accurate temperature reading.

What is the difference between DA and RA thermostats?

Direct Acting (DA) thermostats increase output pressure as the sensed temperature rises, while Reverse Acting (RA) thermostats decrease output pressure as the sensed temperature rises.

What are the fan modes on a Honeywell thermostat?

Auto: Fan runs only when the heating or cooling system is active.
On: Fan runs continuously.
Circ: Fan runs randomly about 33% of the time to circulate air.

How do I set a temperature on the thermostat?

Use the arrow buttons to adjust the displayed temperature to your desired level. The thermostat will show the ambient room temperature and the temperature you’ve set.

What is the “fan mode” used for on a Honeywell thermostat?

Fan mode controls how the fan operates:
Auto: Runs only during heating or cooling cycles.
On: Keeps the fan running continuously.
Circ: Runs the fan periodically to maintain air circulation
