When turning the boiler on the timeclock is calling for both hot water and central heating with the priority being hot water. The heatslave tank heats up to the setting on the hot water thermostat. When turning the hot water tap on the diverter valve immediately moves from 'port a'(hot water) to 'port b' (central heating) with the result of no hot water. This happens even when the heatslave tank is full of hot water.
I have already changed the timeclock, flowswitch and diverter valve which hasn't fixed the problem, as soon as I turn on the hot water tap the diverter valve switches to 'port b'.
The model is a oil Greenstar Heatslave 12/18.
