Programmable stat for 24v heat-only

[chapmanf]

Who knows of a 7-day programmable stat made for a heat-only application? I posted the same question several weeks ago in commercial, but a resi stat would do the trick if anyone has one to suggest.

The application is in a church, and there is a furnace with no A/C installed. The old stat was a heat-cool model and you could count on several calls during the summer from volunteers and staff who had set the stat on COOL and turned it way down and oddly enough the space wasn't getting any cooler.

But all the 7-day programmable stats I've looked at seem to be heat-cool. They really need one that doesn't have any heat-off-cool switch or anything on it that could fool people into thinking it should be able to cool. (A big sticker on the stat saying "don't use cool" looks too tacky.)

Maybe one of the touch-screen stats would do the trick if there is an installer config option that makes all mention of cooling completely disappear for the user.

Any suggestions?

Thanks,

Just make sure you choose a lockable stat...problem solved. Not a lock-box.

Visionpro,Robershaw,others.

Vision Pro, don't worry about the cooling settings. Lock the display via advanced setup. Box just attracts people to break in

And the VP can be told it is heating only but with the display locked...

Thanks - the VisionPro looks like it'd do the trick (finally got an inst manual off the Honeywell site after about ten minutes of clicking and aborting their infinite-looping javascripts about half a dozen times - their web designers need to be put out of their misery).

Nobody in this organization would put up with a locked stat - there are too many volunteer activities and committee meetings at odd times that require overriding the program - but as long as the installer setup has a heat-only option, and as long as that prevents any reference to cooling ever showing up on the display, that'll suit the requirements.

A few years back I saw a commercial programmable (Honeywell?) that was quite different. You could program it and lock everything out after that. *Except* that it was intended for occasional-use spaces, though, so all that a casual user saw was one great big button that said "Space Occupied" or something like that. If somebody pushed the button, it switched to a different program for a few hours, then reverted to the Unoccupied program. If they stayed long than that interval, they kept poking the button again every so often to let the stat know they were still there. Casual users couldn't change anything other than to tell the stat that somebody was around to poke the button.

I have no idea if anything along those lines is still around, but I thought it was novel and clever. This was in the late 1990s and it didn't look brand new then, so it's been a good long while since that one would have been made.

The vision-pro has a partial-lock feature where they can temperarily override the setpoints.
