Pin protected roomstat

[scoobydo123]

Has anyone come across one? My Sister and myself both run a HMO (house of multiple occupancy) and are looking for a pin protected roomstat. I am currently using a Grasslin feeling that although it can be run in anti tamper mode anyone with half a clue can look up how to get out of this mode. Idea is to have a stat that is set for 21c for the morning then drops to 15c for during the day then back up to 21c for the evening. It should also be able to manual override until the next time period for occasions when one or more occupants is at home during the day.

My sister is only running an analogue stat and when visiting for cleaning of communal areas the stat has been wound full up and windows open etc.

Honeywell have a prestige 9000 that seems to fit the bill possibly anyone seen one in the uk?


Tks

most of my landlord customers that provide heating "all inclusive" have the stat located where it can't be reached by tenants several have lockable box covers over the stat. but the best ive seen is the dummy on the wall that does nothing but "click" and the real one is hidden!

Was thinking of doing that but then on days off they cant control it (I am not that mean )

Shame as there must be a market for them.

You could always have two wired in series:

One hidden or modified so that it can't be adjusted, which you use to define the maximum permissable temperature. When this temperature is reached, the CH will switch off, whatever the tenants do with the other controls. You could hide it in a suitably anonymous plastic enclosure, with some air holes of course. Or use something like this: http://export.rsdelivers.com/produc...diaphragm-tamperproof-thermostat/2001314.aspx

And another, easily accessible, which is designed to be adjusted by your tenants to choose a lower temperature if required. This could be your exsisting programmable stat.

You may need to optimise the setting of the "secret" stat by trial and error. Err on the high side to start with, then wind it down degree-by-degree over a few weeks until you get complaints that the place is too cold, then turn it up a tad, and leave it like that. Best done while nobody's peering over your shoulder, of course

But even all of this will not protect you against the kind of tenants that open windows without turning down the heating when they feel too hot
