KE100 Radiators Turning on at Night
I recently bought a set of KE100s and have set them in the upstairs bedrooms. I have smart control enabled, 20c between 18:30 and 22:00 every night and they work great during evening and day.
However they keep turning on at random times during the night, despite being set to off, which is very loud and keeps waking us up. Last night they started moving at 3:30am, despite them being set to off (5c frost protection), night mode enabled (from 22:00 to 6:30) and the boiler itself being off. The temperature at 3:30am was 19c in the room.
I would like them to be completely silent during the night, I would be quite happy if we could set them to automatically go into 'sleep mode - valve open' overnight, to prevent them making any smart adjustments and when the main heating turns on they would just start heating up automatically, but sleep mode does not appear to be programmable and must be manually turned on and off.
I have run the calibration on all.
Is there any way to stop them making ANY adjustments at night, preferable with the valve open? If I can't stop them making noises at night then we'll have to take them out of the bedrooms and send them back.
