Question about Heating & Cooling

System goes on at odd times

I have a honeywell vision Pro TH8000 thermosat. The system is set through the stat to 62 at nite, to go to 67 at 6 AM, back to 62 at 6:45, to 73 at 4:30PM, then to 62 at 1000PM. However it comes on sometimes at 2AM to 73, or the other day it came on at 11AM to 73. Any ideas how this can be fixed?

Try the screen button and clean your screen in the given time.
also try honeywell.com/yourhome and use the contact us. They will try to walk you through and fix the problem as an ac company will usually just try to sell you another. These are not cheap stats I use one myself, I've have mine for years. I know it isn't much but hope this puts you in the right direction.

I have to play with thermostat to get my heating system on


You did not make it clear if the thermostat is a programmable unit or not. I am wondering if the thermostat is not set on the correct heat anticipation setting. A heat anticipater is a small heater that helps the thermostat turn off before it over shoots the desired temperature setting. If the thermostat is set for a 5 degree setting, it will turn off at 63 degrees if set at 68. If the anticipater was set at 1 or 2 degrees, it will shut off the heater at 66 or 67. Newer thermostats will only allow the thermostat to cycle 6 times per hour so if you never reach the desired temp, you have to wait 10 minutes before it will allow a call for heat. Check the installation instructions to see if there is a setting where you can get the anticipator temperature closer to your set temp. Good luck.

No Auxiliaty heat with new thermostat


The Vision Pro is a great t-stat and I have installed many of them with great results. I am wondering though if it is set up correctly. Did you go in and make sure that it is set for heat pump and for 2 stage heating? Look on the instructions how to get into the advance installer options. Go through that meanu and make sure that everything ig set correctly for your type of heating system and that it is set for 2 stage heating. From what you have here and I can tell the wiring should be okay that is why I think that it is in the t-stat programming.

Thermostat temperatures not reaching preset Energy Star settings


Well with a boiler system like you have it will cost you more money to heat your house that way than if you leave it like it is. With a boiler system it takes a lot longer to heat an area than with a furnace. The best thing you can do is find a happy medium and leave it there at all times. If you read the paper work on your new thermostats they have a set procedure which tells the thermostat if you have forced air or boiler system. Do you have baseboard or in-floor heat how many zones do you have.

Honeywell round mercury thermostat - heat not coming on


If you tip the mercury switch so that it makes contact and the furnace doesn't start, it isn't the t-stat. Check the connections, then start checking the furnace.
In any case, ditch the mercury t-stat (recycle it properly) and get a new programmable one if at all posible. It will pay for itself many times over by turning your heat down in the middle of the night and back up by morning.
