What is the make and model of the motorised zone valve?
Good afternoon, I haven't heard back from you.I strongly recommend that you focus on the MZV for starting the fault-finding. Even if it's not faulty, it will tell you whether the fault is upstream (i.e. with the thermostat or programmer), or downstream, i.e. the boiler.
