Asked 8 years ago by Sitruc.

• A:Answer You will need to have a "C" wire in order to use this. If you do not have one, there are additional instructions on how to wire it and it includes the wire you can use to jump it in your thermostat. If you have minor DIY skills, you should have no problem with the installation.

Q: QuestionFor those who use this thermostat for both heat and AC, say it’s July and you have the nighttime temperature set to 72 until you leave at 8am. Then it’s set for 78. Will the heat go on to make up that 6 degree difference? I know it shouldn’t but..:.

Asked 7 years ago by WRJW971.

• A:Answer Hi there! The Honeywell Smart Color Thermostat does have the ability to be setup for Auto Changeover; this will allow the thermostat to turn on heating or cooling as needed based on your schedule setup. However, the heating and cooling set points must be at least three degrees apart and the heating set point is unable to be set above the cooling set point. So for your example, if your cooling set point is 72 degrees, you would only be able to set your heating set point to 69 or lower. To answer your question, this thermostat will not turn your heat on to bring your home up to the 78 degree set point you have chosen for the next scheduled period. It will allow the house to naturally get that warm if it is able to, and if it does, the thermostat will turn your cooling on to maintain the 78 degrees if necessary. I hope this helps!

Q: QuestionHow can I determine if I have the "C" wire? Do I have to remove the existing thermostat?

Asked 8 years ago by Lee.

• A:Answer You will need to remove your old thermostat to determine if you have a C wire. Just because it's there don't assume it's real. You will need your system powered on to test. You need to CAREFULLY, using a volt meter set on AC, measure the voltage between the R ( could be RC in some cases) wire and the C wire. You should see 24 Vac. It could be as high as 29 Vac when nothing is running, and nothing will be with your thermostat removed. If you have the voltage then the C wire is real and you can continue. If not consider having your system updated to include it.

Q: QuestionHi. I have a regular Honeywell thermostat. I know for sure it uses AA batteries. Does this mean that I don't have c wire and then I won't be able to install the new smart thermostat?

Asked 7 years ago by Mike.

• A:Answer You will need to confirm if you have a common wire or not. You can not tell simply by the thermostat needing batteries or not. Some thermostats used the batteries for display illumination or to hold the program memory in case of a power outage.

Q: QuestionWill this model thermostat work with a heat pump equipped with an emergency heat coil?

Asked 5 years ago by Buzz.

• A:Answer Yes, I have this thermostat installed on two heatpump systems that have Aux heat coils. My systems have an automatic low outdoor temperature cut out relay that cuts off the heatpump and energizes the heating coils whenever there is a demand for heat and outdoor temperature is below 27 degrees. When outdoor temperature goes back above 30 degrees, it switches back to the heatpump. The thermostat can also be set to emergency heat in case there is a problem with the heatpump itself. My thermostats have wires connected to the following points: C R Y G O E/Aux During the thermostat setup, you will be prompted with questions regarding Y, O and E/Aux, I chose the default prompts and my systems work fine. Hope this helps.
