Hi guys..
We have a honeywell 3 port valve and horstmann cylinder, wall stat and programmer which was fitted recently..spent a week looking for a heating engineer to do the work but all too busy, so a sparks mate of mine came around to fit these with me..both heating and hot water now work fine ..except the 3 port valve remains open [heating side] even when the wall stat is satisfied..this remains in this position unless the tank stat asks for heat then the 3 port valve moves to the hot water postion...
strange goings on !! any ideas please???
