I'm one of the trustees for my church. One of the problems we have is people forgetting to lower the thermostat when they're done with a room.
We would like the thermostat to be programmable to heat at certain time periods or to go to a set-back temperature but with the option for the user to override temporarily up to a certain time period. The thermostat should also be lockable such that no user can change the settings except to temporarily move it out of setback temp mode. We're open to having a separate mechanical/electronic timer and a thermostat if there's a way to pair them together.
It seems that the Robert-Shaw 300-229 thermostat would meet our needs. Are there any other timer/thermostat manufacturers we should consider?
