I read somewhere that if the lever n a zone valve is put to the Manual position it should then move back to the Auto position when the system starts up as normally i.e. when the programmer tells it to.
On mine, I went to drain it down to clean it out and noticed the lever was in the manual position, so I left it there after the cleaning and it doesn't move back. So I have now put it to the auto position and my wife tells me the HW is now taking longer to heat up.
How can I be certain that both the HW & CH are getting their fare share on the heat ???
