Hello,

I have an old Honeywell Thermostat T8195B. I was wondering what would be a good replacement. Only have furnace heating. No cooling.

Also, the location of the T-stat is in the a place where there is no forced heat vent so it is not the place to measure temperature. I know I can relocate it but I am looking for a wireless remote sensing option if these things exist. My thinking is that I can put the sensor in the bedroom area to control to it.

Thanks!

You want the thermostat located where there is not much air movement. That gives the thermostat a good area for sensing the correct temperature and not around where drafts or moving heated air will cause the thermostat to have a inacurate reading.

There are many different models of thermostats available and from many different vendors.

Thanks for the quick feedback. Did some research and am thinking of getting one of the two following Honeywell t-stats from my local store

RTH230B $39
RTH6400B $70

Will either work? I have a basic gas furnace with no cooling. Also, any recommendation on which one should I go for?

Thanks.

Take your pick they will both work. You will probably need to use batterys also.

If you only have two wires to your thermostat, I would go with a thermostat that doesn't require a battety to operate(battery dies, furnace dies). Are you looking for a digital thermostat, or would you be contempt with a basic t87f honeywell.

I prefer a digital t-stat. my old T8195B had power in addition to batteries? Is that the C wire? I always thought the battery was for backup only. IS it different on the RTH230B?

If you have a common then you will not need the batteries. If you do relocate the stat remember that it should be placed on an INTERIOR wall, about 5 feet up from the floor.

Batteries may still be required. With a C wire, the batteries are not ESSENTIAL.

I just read the installation instructions for the RTH230B and there is no C terminal. I guess it is 100% based on batteries.
