Hi All,
Recently I have noticed the mid position valve on my plumbing system appears to be clicking. Upon doing some investigation, it appears that with the controller set to CH only, the system does not fire into life. If HW is then selected with the CH still set on, the pump fires into life, the valve moves from the H position to the M position and heating and hot water warm up. If i then pull the HW tank thermostat away from the side of the tank or turn the setpoint down (with CH & HW Still selected), the valve moves back to the H position and the pump and the boiler stop. With HW only selected, the system seems ok. The plumbing/control system has not been touched at all and has worked ok until recently. Is this likely to be an issue with the valve itself, or some other element of the system? The valve is an iFlo MA1.
Thanks for advice in advance!!
