I am renting a townhome and cannot reprogram the thermostat. It is a Honeywell Magic Stat Model #97-4730 Rev. A. I looked on line and could not locate this number.

The red light only comes on for a call for heat. You can go on line and go to the Honeywell website. Go-to thermostat instructions and put in your tstat model and it will tell you how to wire and install the stat

yes just make sure u relace all the wires in proper order, r-rc, w , y g,, remove one wire from old stat and install on new one or make drawing and write down all wireing colours and letters

Check the stat for continuity using a VOM. Check connections? Reset and Reprogram system. Lastly call Honeywell.

Without speaking with you live I can only suggest you call 1800 Honeywell they have excellent experts there to walk you through the setup of your stat, you could kill the power to the unit 1 hour and remove the stats batteries to reset to default but calling Honeywell will be a better easier experience.

Remove main stat from subbase. On back of main stat there are some screws used for different settings. Screw "C" if for fahrenheit and celcius. Screw in for fahrenheit and out 1 turn for celcius.

The model number is going to be on the thermostat. It is not unusual for the number to be on the back of the stat, meaning you may have to take it off the wall. It could also be found betweenthe base ans the stat.

Once you have the model number googel "Honeywell XXX" with XXX being the stat model number. If you can't find the stat, you can go to the Honeywell web site and do a search, matching your stat, by the pictures and functions. It is a bit tedious, but it works.

Sounds to me like you have a low voltage short. If the stat had no display until you installed the battery means there was no voltage for the stat to work. Putting the battery in proves the stat works, no motors turning on probably leads to a blown low voltage fuse generally a blade fuse on circuit board in indoor unit. Good Luck

Precisely because it is a very old, round type device
