You can turn it down to 55 degrees so that it wil still come on but not freeze, be sure to open the cabinets underneith the sinks so that warm ait will migrate down there to help them from frezing.

Honeywell thermostat blows cold air on heat

Thermostats don't actually blow anything, the heating system might though. Check the breakers for your heat system, then call a heating specialist. They're really not that expensive.

How do you change battery on honeywell thermostat

first of all it is not a battery according to a HW tech., it is a capacitor that charges or stays charged by the current coming from the transformer on the boiler or furnace or on an a/c,etc...I know. it's an energizer # 2025 or sumptin' like that.That's if we're talking about a T87N or T87K, otherwise just pop open the lid and replace yer' batteries!

We have a fairly new furnace. I have the temp set at 65 the furnace only runs for 3 min at a time and comes on every 5 min. This sounds extreme to me?

It depends on the differential that you have programmed into the thermostat. In most of them you can set the temperature you want the thermostat to activate, and then you set the run differential such as three degrees below 65. In other words, the thermostat will activate at 62, and drive the temperature up to 65, cut off and wait for the temperature to drop to 62, where it cuts on again. see:

Check to see if you can find the manual if you have lost yours.

My honeywell t87n is adjusting the heat setting by

This sometimes happens over time with some digital thermostats. The easiest solution is get a toothpick and hit the reset button. From there just set it as you normally would. That should solve your problem.
