Okay, not the 'accessibility' problem I had in mind.wife puts the tumble dryer on in the utility room stat is in the hallway so heat builds up and knocks the stat off
Can you move the thermostat to the living room? As long as there is a sun-free location and they don't have an uncontrolled heat source like a log fire, this works pretty well. Actually, for the elderly who tend to spend more time sitting around than working-age folk the living room is in many respects a better location for the thermostat.
