hi
i have an ep4002 controlling my c/heating[seperate boiler for h/w], it wont turn off at night despite checking all settings to be off by 9.00pm, i.e. the heating continues to run, rads hot, gas bill the size of a small planet. Ii have swapped out the controller for a spare - no luck......I have reduced the rad stats to low, droppped the room stat etc, could it be a by pass valve / zone valve [or something else] - not too clued up on these things.
Any help would be appreciated
