Sounds like you may have a frost stat which runs the CH when the outside
temperature falls to a certain level - even if it is otherwise switched off.
Try to find it, and check that it's not set at too high a temperature.
After ruling out the frost 'stat outside, it could be that the switch
terminals on the timer have eventually welded themselves together. If the
timer is the same age as the rest of the system, I'd start looking there.
You will need a meter that can produce its own readings in the Ohms range to
check it properly. Remove the timer from its back plate and check across
the HW and CH connections to see if they are opening and closing as they
