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 change-over valve.
- Use a small piece of wire (not supplied) to connect W and Y terminals.
- Set fan operation switch to Heat Pump (see page 5) and configure system type for heat pump (see page 6).
- L terminal sends a continuous output when the thermostat is set to Em. Heat. Connect to Honeywell Home zoning panels to switch the panel to Emergency Heat.
- Install field jumper between Aux and E if there is no emergency heat relay.
Fan operation settings (TH3110D 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: hang the switch to this setting for heat pump 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 4 tabs on the wall plate with the corresponding slots on the back of the thermostat.
- Push gently until the thermostat snaps in place.
- Push excess wire back into the wall opening.

FAQs Honeywell Pro 3000 Series Non-Programmable Digital Thermostat
How do you use a Honeywell nonprogrammable thermostat?
If you have a manual thermostat, setting the temperature on your Honeywell thermostat is simple. All you need to do is to press the up and down buttons to set the temperature. The temperature you set will stay until you change the temperature again.
How do I reset my Honeywell Pro 3000 thermostat?
Resetting a Honeywell Thermostat Power off the thermostat and remove the batteries. Put the batteries in the wrong way, with negative to positive and positive to negative. Wait ten seconds and put them back in the correct way. Your thermostat will be reset to factory settings.
How long does a nonprogrammable thermostat last?
As with all other systems, your thermostat will eventually become old and outdated. The lifespan of most home thermostats is 10 years. However, you may need to replace yours sooner as newer, more efficient thermostats enter the market.
Why is my Honeywell thermostat not changing temperature?
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 lifespan of a Honeywell thermostat?
Thermostats don’t typically have a set lifespan for maintenance, repair, or replacement (unlike air conditioners that need a tune-up every year). Still, you can generally expect your thermostat to last at least 10 years. After a decade, thermostats may start malfunctioning.
Does the Honeywell Pro Series need batteries?
Batteries are not required if the Honeywell T6 Pro Z-Wave Programmable Thermostat was wired to run on 24 VAC power when installed. To provide optional backup poweinstall three fresh AA alkaline batteries immediately when the low battery alert appears.
What is a non digital thermostat called?
Analog thermostats are the most basic kinds of thermostats and they are also the least expensive. However, they are not as accurate when it comes to displaying the temperature of the home. Digital Thermostats.
What is better a programmable or non programmable thermostat?
Here’s the answer: Both a programmable and non-programmable thermostat have the potential to save you money if you know how to use your thermostat correctly. However, a programmable thermostat changes your home’s temperature automatically and therefore makes it EASIER to save money.
What causes a thermostat to fail?
Thermostat failure can be caused by contaminated fluid or simply an old thermostat with weakened springs. Contamination happens when incompatible coolants are mixed, old coolant is not changed as recommended or particulate matter from gaskets or elsewhere breaks off.
Why is my thermostat not controlling my heat?
If your thermostat is not working, change the batteries, make sure it is turned on, the thermostat is set to the correct mode, check the power supply and airflow. If your thermostat is still not working, the best thing to do is call an HVAC professional! hey will be able to help you diagnose and repair the issue.
