NOTES
Wire specifications:
Use 18- to 22-gauge thermostat wire. A shielded cable is not required.
- Power supply. Provide disconnect means and overload protection as required.
- Remove jumper for 2-transformer systems.
- Optional 24 Vac common connection.
- The common connection must come from the cooling transformer.
- Use either O or B terminals for the changeover valve.
- Use a small piece of wire (not supplied) to connect W and Y terminals.
- Set the fan operation switch to Heat Pump (see page 5).
Fan operation settings
TH2110DV/TH1110DV only:
- Gas or Oil : For gas or oil heating systems, leave the fan operation switch in this factory-set position. (This setting is for systems that control the fan in a call for heat.)
- Electric or Heat Pump : Change the switch to this setting for heat pumps or electric heat systems. (This setting is for systems that allow the thermostat to control the fan in a call for heat, if a fan wire is connected to the G terminal.)
Thermostat mounting
Align the thermostat with the tabs on the wallplate, then push gently until the thermostat snaps in place.
Installer setup

Special functions
Early Start (Setup Function 13): Early start allows the heating or cooling to turn on before the program start time, so the temperature is reached at the time you set.
Compressor Protection (Setup Function 15): Forces the compressor to wait a few minutes before restarting, to prevent damage. During the wait time, the message Cool On or Heat On (heat pumps only) will flash on the display.

FAQs Honeywell Pro 1000 Series
What is the lifespan of a Honeywell programmable thermostat?
The normal lifespan of a thermostat for upkeep, repair, or replacement is variable (unlike air conditioners that need a tune-up every year). Yet, in general, you can count on your thermostat to endure for at least ten years.
How does a thermostat that isn’t programmable operate?
The most basic choice is a thermostat that is not programmable. You may set the temperature, activate the system fan, and turn on the heating or cooling system using this kind of thermostat. Since all adjustments must be made by hand, non-programmable thermostats may also be referred to as manual thermostats.
How does the Honeywell thermostat get power?
When the R/RC terminals are “supplied” and the C terminal is “returning,” the thermostat runs between 20 and 30 Volts. The thermostat needs a C wire that is linked to C on the apparatus in order to power itself. Make that the power switch is turned on, the breakers are active, and the furnace/air handler door is shut.
Are batteries used in Honeywell Pro Series thermostats?
There is a low battery indicator light on Honeywell thermostats. You’ll have roughly 60 days to change the batteries after this light turns on.
What is the Honeywell thermostat’s operating range?
On open fields, the 868MHz band Honeywell Home Radio Frequency communications has a range of 100m. The Honeywell Home wireless thermostats can attain a typical reliable range of 30m in a household environment, depending on the construction of the house and the number of walls separating the communication devices.
Would a Honeywell thermostat still function if the power goes out?
The set point and schedule are stored by the thermostat, yes. The only data the thermostat “loses” when the power goes out is the time right now. The thermostat will resume its previous settings and configuration as soon as the power is restored. Moreover, it will automatically rejoin the WiFi network.
Does the Honeywell thermostat set the time automatically?
If your thermostat has this feature, it will change the time automatically based on the location where the device is registered. You will need to manually change the time and date on your thermostat if it lacks this auto-updating feature or if the date is not enabled.
Honeywell thermostats turn off for what reasons?
The blank screen on your Honeywell thermostat can be a sign that the furnace door wasn’t completely shut. These thermostats are set up to completely turn off if the furnace door is open. Verify that your furnace door is completely closed to rule this out.
Why would you use a manual thermostat?
Non-programmable thermostats are preferred by some people because they make it simpler to adjust the temperature of your home in response to changing weather conditions. With programmable thermostats, it can be more difficult to change the program when a heat wave or a cold front arrives unexpectedly.
Thermostat functionality without Wi-Fi?
Because they do not totally rely on the internet to function, smart thermostats can operate without Wi-Fi. The functionality will be restricted to managing your home’s temperature settings and keeping track of your energy consumption.
