How to program Honeywell thermostat for remote sensor

I have a Honeywell thermostat model TH8110U1003. There is a remote indoor sensor connected to the thermostat which the thermostat seems not to recognize. I believe the thermostat was not programmed to accept the remote sensor. I tried to program the thermostat but cannot get the thermostat to setup function 0340 which is the remote sensor. Can someone help me to program the thermostat?

Remote Sensor (Setup Function 0340): If an optional outdoor sensor is installed, the thermostat can display the outside temperature. If an optional remote indoor sensor is installed, the thermostat will display the temperature at the sensor location (the internal sensor in the thermostat is not used).

Honeywell thermostat


Honeywell has made a huge number of thermostats over the years. Directions for each are specific to each model. Your model number will begin with the letters, T, TH, RTH, C, or CT and is on the back of the thermostat.
Once you have the model number, you can obtain the owner & programming information by supplying it on the Honeywell webpage, here.
If you are having trouble, either contact Honeywell directly - or repost here.
Good luck!

Honeywell TH8320U Thermostat


The Honeywell Vision Pro 8000 Digital Thermostat is a fully programmable thermostat that is so easy to use that you might think that it is reading your mind as you work with it.

This intuitive logic responds to you as you program this thermostat and helps you to do what you wan to do. The instruction manual almost becomes a thing of the past. This thermostat also will learn your building and HVAC system. It then adjusts to keep your temperature within 1 degree F of the set point. This will give you the best in comfort. The comfort is achieved while still giving you the very best is efficiency. In some cases efficiency has been increased by up to 30% by simply installing this thermostat.

The fan can be programmed separately for increased comfort when running an electronic air cleaner or a humidifier. A 35% circulator mode is also available. Hold options will let you easily go on vacation or temporarily override the programmed settings. The vacation setting will even let you set it to go back to the schedule before you get home. There are also built in reminders for many of the things that need scheduled maintenance.

If you are thinking about or have a dual fuel set up or a heat pump furnace set up, then this is the thermostat for you. With the addition of an outdoor sensor you can set the thermostat to switch from one heat source to the other at whatever temperature you set.
This feature will eliminate the need for “change over kits” extra relays, etc… when you are setting up a system that has a backup heat source.

This thermostat will also allow you to run it from the power of your HVAC system or run it on battery power. Just hook up the common wire and the thermostat will run off of your HVAC system. The changeover of the unit from A/C to heat can be programmed to be either manual or automatic. Scheduling of the program can be done in many different ways. You can decide between 1 day, 7 day, 5+2, or 5+1+1, day. Four periods, 2 periods per day or nonprogrammable are all options also.

The keyboard can be locked completely or partially. With the purchase of additional sensors you can wire up remote indoor sensors. These can also be wired to average the temperature is you want to sample the temperature from more than one place. An outdoor sensor can be installed so that you can see from your thermostat the outdoor temperature.

A five year manufacturers warranty is standard and you will also get a thermostat that has earned the energy star rating.

One of the best features of this thermostat is it’s big clear backlit display. The current temperature, the set temperature and the date/time of day are displayed at all times. Simply touching the screen also activates the back light feature.

This digital thermostat has a menu programming guide the helps you through the process of setting up your schedule. You are able to select multiple days and customize the thermostat for any kind of unique schedule you may have. This thermostat also let’s you take it off the wall and still be able to program it. This lets you watch TV and program it at the same time.

There are built in backups that will hold the time for you if the power goes out. This t-stat will also update for daylight savings time. There are HOLD features that allow you to modify your program and hold it and then go back to the original.

Change reminders that are built in include the air filter, UV light, humidifier service and of course the batteries of the thermostat. The blower of you furnace can also be programmed to run extra to help increase the air quality in your home.

If you decide you want to know the outdoor temperature you can purchase an additional sensor and then hook it to you thermostat. The outdoor temperature will then be displayed on you thermostat. This feature also gives you the capability of using the sensor to monitor indoor temperatures remotely.

This thermostat will keep you very comfortable as the variation typically in temperature from set point is less than 1 degree F. The thermostat after a period of time learns the characterizes of the way the house or building heats and cools and then adjusts to get the most efficient operation of the heating or cooling system while maintaining a very close temperature tolerance.

By changing a few of the parameters in the thermostat this can be can be configured for either single stage conventional heat/cool systems or any single stage heat pump system.

I HAVE A HONEYWELL MANUAL THERMOSTAT NO BATTERIES ALL IT HAS ON THE BACK IS T8400C 1099 (2) 0710 1B HELP, IT DOES NOT SHOW ANY THING THE SCREEN IS BLANK


This model of Honeywell thermostat uses the 24v from the unit to power it. One of three things must have happened.

1. You have lost power to the furnace, therefore no power to thermostat.
2. You only have 4 wires hooked up on the thermostat and not 5. A lot of older homes had just 4 wire running to the thermostat, which will not work for this thermostat. You should have a wire connected to the (C) or (B) terminal on the thermostat, which ever one they have, I can't remember off hand. These are the Common terminals. They have to have the common from the furnace 24v power to operate.
3. Faulty thermostat, which will obviously have to be replaced.

Hope this helps and gets you to cooler days!

TH8110U1003 Touch screen thermostats. My problem is I don't have a manual to show me how to operate it. But the big problem I'm dealing with now is when I set a temp. say I set it for 75 and the house...


If your program that you have programed into the stat is set to 73 it will go back to that setting if the stat is in the program mode....... Push the HOLD button on the stat and keep pushing it till it say permanent HOLD right above the buttons on the bottom and then you can set your temp to what you want. Here is a download link for the manual from Honeywell..

Im changing an old honeywell thermostat with a new honeywell thermostat. the old on has wires 4 wires connected to 4 screws C,R,G,W but the new thermostat has a place where the wires go which are...


Yes, I believe that you will be fine. If the original wiring is correct then I have listed the basic wiring below. As always read the directions and make sure the wiring matches your system.

Red wire = Rh (24v power, should have an exsisting jumper to RC)
White wire = W (heat mode)
Yellow (or sometimes blue) wire = Y (A/C)
Green wire = G (Indoor Fan)

How do I change the temperature range on a Honeywell TH8110u1003 thermostat. The range now won't let me go below 77 in AC mode.


Try adjusting the heat range up. Set it a 77 then try the cool.
I believe the Honeywells have a max range between cool and heat.
also sometimes there is a lock out code on them you'll need the book.
Good luck
