Noticed today when opening my zone valve manually that the arm doesn't make
contact with the end switch,thus not engaging the pump.(I am having problems
with this zone.)
I then increased the heat on a working zone and watched as the lever
depressed the end switch,allowing the circ. pump to come on.Question
is...why doesnt the manual lever contact that switch?...even tried the
working zone valve manually and it didnt contact the switch.Is there a
reason why it doesnt depress the switch when done manually?
