Any thoughts? Thanks - Bill --173.63.xxx.xxx

There are 2 temp bulbs you want to use - 3 if you have a/c, put a 55/60f parallel with white/red behind the stat, then a 75f in series with the white wire to limit the heat there - no matter how high the wall stat shows, if you have a/c in the blower box you put a 75 in series with the condensing relay wire - c terminal. --76.188.xxx.xx

Our Honeywell thermostat is remote controlled from our phones, and only people with the password can change things. But the actual thermostat is still in the house, you'd have to put a locked thing on it like the do in some offices I think? --50.82.xxx.xx

I have seen some around that are designed to make people think they can change the temp, when they cannot. --64.251.xxx.xxx

A cover can be thwarted with an ice pack placed on top of it. I had to share an office for awhile with an overdressed chubby chick. My chair was up against the AC unit and I was freezing. So I got an ice pack and found the thermostat and put that ice pack up against it. Chubby chick was getting AC from the hall anyway and eventually wore fewer layers in the summer --73.178.xxx.xx

Thanks everyone!!! --173.63.xxx.xxx

I have not tried. landlordthermostats com has Temperature Limiting Thermostat. They said it is for landlord. --97.91.xxx.xxx

I always do not understand why some tenants have windows open in winter. --97.91.xxx.xxx

CJ, that would do it for limiting the max set temperature. I'd still like to have something to insure the heat stays on during winter break. Thanks. --173.63.xxx.xxx

There are wifi thermostat, we can control remote. We need to have internet, or we need tenant permission to use their internet. Internet is expensive about $70 a month. --97.91.xxx.xxx

Bill Wils,I think C J is onto something,otherwise check with your supply house...............charlie............you won't need it for another 9 months.................................... --174.199.x.xx

I have tried the landlord stat but very easy to reset back to good ol regular t-stat, Bill visit a good hvac store to ask about these small temp bulbs, or your hvac person can prolly get them, I see the sales person at a show that occurred in March - next in Sept. You stuff the heat ones into the wall so they feel the room but never really sure where at, the a/c limiter goes in the blower box which is very close to the control board - the house fan keeps running keeping the air temp stable but the chiller goes off and on to preserve the life of the condensing unit. Wish I knew what the trade name of these thing is, maybe Gevans will stop in. --76.188.xxx.xx

I agree Charlie, CJ is on to something. All of my houses have wifi and I'm thinking of including wifi in the rent, so it's even more interesting. --173.63.xxx.xxx

If there is hot water radiators then installing non-electric tamper resistant radiator thermostatic valves made by Danfoss or Honeywell Braukman. Tekmar manufactures electronic boiler controls which limit to less then one degree Celsius. Forced air is more difficult as will have to install a completely different system. It always worth viewing videos on You Tube to look at other options. --31.19.xx.xxx
