Customer Questions & Answers

We have 2-wire circuit. If this a 3-wife connection we cannot use. Which connection is it?

Asked by: Leonard
The Honeywell RTH8500 is rated for a minimum of 20 Vac to a maximum of 30 Vac, at 60hz. It can be used on a range of heating and cooling systems. To understand what thermostats would be compatible with your system we would need to know the make/model of your current thermostat, its voltage rating, the type of system you have and the designation for terminals that have wires attached. When you have this information please call the Honeywell Consumer Tech support line at 1-800-468-1502. Sincerely, Honeywell Customer Care

What does the blinking red light mean?

It lights up either when the thermostat is set to the emergency heat position or if the thermostat detects a problem with the heating and cooling system. Please give us a call at 1-800-468-1502 so we can look into this further for you. You can reach us from 8:00 a.m. to 7:00 p.m. CST, Monday through Friday; 8:00 a.m. to 6:00 p.m. CST on Saturday and 9:00 a.m. to 6:00 p.m. on Sunday.

How do I remove my old Honeywell RHT8500D

I have a zoned A/C heating system
Asked by: Char
Hi Char! If you are looking to remove the thermostat RTH8500D from your wall, follow these steps: Turn the power off to your system. Remove the thermostat faceplate from the base on the wall. Remove the wires from the thermostat base on the wall. Unscrew the base from the wall. This should be all that you need to remove the thermostat. I hope this helps. Thank you.

Will this thermostat work with a dual fuel system. Does it have outside temperature?

Replacing a Honeywell that works iwth RUUD dual fuel system. Current Honeywell has outside temp to show when unit converts from electric to gas. Will this thermostate work for my system?
Asked by: Bob
Hi Bob! Yes the 7-Day Universal Touchscreen Programmable Thermostat does have the ability to control a dual fuel system. You can configure this thermostat for a heat pump with gas/oil back up heating. I hope this helps. Thank you.

Heat pump or emergency heat?

If I set the night time temperature at 60F and morning (6am) temp at 68, will the emergency heat come on at 6am or just the regular heat pump? Our current non-programmable thermostat turns emergency heat on if the "set temp" (68F) is more than 1 degree higher than the existing room temp (62F). The only we way could avoid having the emergency heat come on in the morning is by manually changing the "set temp" one degree at a time, which is a hassle. We would like the new thermostat to use the heat pump instead of emergency heat unless outside temp is too cold for heat pump to function.
Asked by: Anonymous
When you program the thermostat for a heat pump with a back up heat source it knows to use the heat pump compressor as its primary source of heat. It will use the back up heat when it needs help to reach the set point temperature. Typically that is when the compressor has been running for an extended period of time and not reaching the set point temperature or when there is a large gap in the room temperature and the set point temperature. These are algorithms built within the thermostat so it will happen automatically.

Will this thermostat work with a steam boiler?

Looking for a thermostat that can be adjusted for a steam boiler.
Asked by: Solidventur
didn't work for me so I purchased a LUX TX9000TS and had heat in home in 10 minutes. Lux is cheaper, has identical features and will "plug and play" nicely with my gas fired Burnham steam boiler beautifully

Installation was fairly straight forward since I was just matching wire for wire with the previous unit. Otherwise, I highly recommend having a professional do your installation. Even with my personal knowledge and experience, I found it hard to understand the the correct programming to make it compatible with my heating and cooling system. Also the programming is too difficult for most people. I do not recommend this unit for senior citizens.

Only issue I have with these thermostats are that they will not lock. In other models of this thermostat you can lock the screen in the installer setup. This helps prevent people from messing with the settings. This thermostat does not offer this feature. Other than that the thermostat is fine. Great for residential applications!

Easy to install but programming function was not as direct as one would desire. Also, the unit was purchased for an individual with eyesight issues and in spite of the larger display of the current temperature, the rest of the display was not visible to them, even using a magnifying glass. Might it be ok for another application? Possibly, but it was not a solution for us.

This programmable thermostat was easy to install according to package instruction. It is straightforward to program and maintains a stable temperature within 1.5 degrees of the set temperature. I have had the thermostat for about 3 weeks so I cannot evaluate the longevity of the device. I am satisfied with the product.

Rated 3 out of 5 by from For convenience. This was purchased for the auto switch from cool to heat feature. The heat hasn't needed to be used yet, but the "cool " function seems to be too sensitive. The A/C cycles very often, and seems to make the house colder than it should be, considering the cool setting "value."
