Ian my bad not following instructions correctly! But am good and meter read as per your initial help!
If possible just to enlighten my knowledge on 3 port valve will appreciate your help!as mentioned earlier
I have st6400c programmer the switch on the valve stays mid position when hw or ch or both are demanded
Is this normal ? Should the switch motor to manual when only hw is demanded then return to mid position?
Thanking in advance
