Hi My Dad is currently going through tests for early onset dementia. He lives on his own but with carers coming in twice a day. One of the illogical things that he does is to whack the heating up, open the window and sits in a short sleeve shirt. It is a constant round of too hot or too cold. Sometimes the flat is at 26 degrees! I've tried only leaving long sleeved shirts and jumpers in full view but to no use. I've tried telling him not to change the thermostat or the radiators but to no use. He no longer has any understanding of the link between the thermostat and the radiators. Is there any way of preventing him from changing the thermostat - short of taping it up so that no-one can change it? Or any other ploy that I could try to keep him and his flat at a reasonable temperature?
