Hi guys.
Southwark council have just kindly installed a new central heating system into the home of one of our local OAPs. they have dementia too and are having a terrible time adjusting these to the correct temperature, usually resulting in them all being left full on, the house was 28c when we visited last and all the rads were set at maximum, keep telling them to leave them on 2 but it's no use. Is there anyway to lock these into a particular setting, say number two? I took the valve tops off but this simply opens the valve fully on, so no good. short of wrapping them in duct tape or putting a screw in the side, are there any other bright ideas?
Thanks.
