Heating Staying On With Hot Water

A customer asked me to look at their heating as the radiators had been coming on whenever the hot water was heating. Sure enough the heating was a three-port motorised valve system and had the ACL Drayton Lifestyle valve that pre-dated the latest MA1 version.

Unlike the MA1 version the earlier one does not have a "snap-on" actuator. For this reason it was difficult to discover whether the spindle was seized or the synchron motor. It was late on a Friday when I looked at the job and wasn't going to be cold, so I opened the actuator, removed the sychron motor and forced the mechanism to the hot water only position. This kept the hot water working correctly until I was able to return and replace the motorised valve.
