Hi,
Can anyone help. I have a Baxi Genesis 80 combi that is misbehaving. On HW everything is fine. On HW/CH everything works as it should but the danfoss pump is running continuously. There is no room thermostat. with the CH control knob turned to minimum and no demand for HW the pump continues to run. Could it be a flow switch or PCB. The manual shows a "safety thermostat" clipped to the pipe at the 3 way valve - is this used to determine whether overrun should be switched off. Thanks.

John
