Honeywell White Round Thermostat - 4degF Heating Offset

Only thing you are missing is that you are trying to fix a crappy T-stat. They have been around for years and not usually accurate.

My only suggestion is to replace it with anew, more accurate T-stat and save a lot of aggravation in the long run. The round Honeywell was not all that good in 1950 and no better today.

If the ring shaped cover doesn't come off, how was it mounted to the wall to begin with? My bet is 99% the ring just pries off like all the similar that I've seen. Google for manual or check Honeywell website?

_________________ Ed:

It is not widely known that Honeywell still makes the classic round. One way to tell the vintage of one is by the color - newer ones, like ours, are white.

Older ones tend to be tan matallic or silvery metallic.

___________________ trader_4:

There are two circumferential grooves - one behind the outermost(dome shaped) ring, and a second groove, about 3/8inches behind it.

I get resistance to a flat edge inserted and turned, in both grooves.

Also, the unit does not rotate, even when I grasp and attempt to rotate it.

Googling Honeywell is difficult, since, as I mentioned to Ed above, they still mfg half a dozen updated variants of their round model. Soooo, not so easy to find instructions for getting inside of, or removing this thing from the wall.

Youtube video might be useful ?

_________ Thanks, but mine looks more like this - not the double grooves as I mentioned, above:

NOTE the double grooves - sorry, typing skills gone south since college!

1. the youtube video might help you in removing the cover 2. with cover removed you can find the exact model number 3. when your know the exact model number you can use it to : search and download the instruction manual : search for more-exact youtube help Good luck. John T.

Have you measured the temperature where the thermostat is located?

______________________ I found the manual for what I think is the one we have - a 'T87K' heat only:

Folks: I DO NOT WANT TO BREAK MYSELF OUT OF A LEASE if something goes wrong!

Worry much ? John T.

Why is this your problem rather than the building owner's? Can you do something to the pointer to make it match up with the actual temperature even if it's something crude with a label maker?

Because I know the proper solution, that's why.

My problem is, agonizingly simple at that, accessing the part of the t-stat to check it.

And besides, we're renting on the cheap, all utes included, no complaints. So know-it-alls, and fix-it tenants with fundamental knowledge, like me, can kindly hold their tongue.

Lease?? I thought you were the landlord. If you have a lease, I'd contact the landlord and/or building manager.

Read my reply, directly above yours.

Yeah, they "crossed in the mail". I understand your pride in being able to do most handyman tasks but I doubt you would be breaking your lease by contacting the owner or building manager. However, damaging the thermostat or the wall where it's mounted is likely to cost you $$. If not soon, then from your security deposit when you move out. Easiest solution is to just keep setting the thing 4 degrees warmer to compensate. Of course, if the wall behind the thermostat isn't insulated, the thermostat could be correctly reading the temperature at that site.

What's wrong with that? God did not create the thermostat. It could be wrong, and changing the setting is the easiest way to allow for that. If you have tenants, they should be smart enough to understand your explanation.

None of that matters. All that matters is that you need to set the thermostat "setting number" higher than you have been. It's not actually the temperature. It's just a number. Some thermostats, like my water heater, don't give numbers, just lines. so that people don't get wrapped up in thinking the number has to be correct.

I don't see how adjusting anticipation would help. It turns the furnace off a little bit before the desired temp, so as the room continues to warm up, it will stop at the desired setting. Whatever it does, now you don't have to take the cover off. ;-)

You're the tenant! Just set it higher, maybe 4 degrees. Think of all the time you'll save so you can argue about politics.

You can't remove the thing from the wall without removing the screws holding it to the wall and that requires removing the first ring, the one closest to the center, ah, the one you yourself refer to.

You can't remove the ring because the landlord glued it on because of tenants like you. Or at least one tenant at one time who fiddled with it improperly.

Just set the thermostat 4 higher, and be done. That's what I would do even if I owned the place and even if I could get the ring off.

Your last point brought up the biggest issue - at least with our boards: too MUCH politics on a home repair Usenet group!

I get what you're saying about the thermostat set vs actual numbers thing. It would be good though, if both were withing one degree of each other, for a baseline on how well the system is regulating heat, for oil consumption purposes.

Pull it off. If you break it replace it.
