We have had a brand new Honeywell 3-way motorised valve fitted, controlled by a Landis & Gyr RWBXP programmer. It is an open system, with header tank.
The boiler is an Ideal Classic FF230, which was serviced in 2013 and given a clean bill of health.
If we use the CH option (manual or via timer) the motorised valve is still switched on and warm to the touch.
The only way we can get the valve to shut off is turn off the power to the central heating boiler/motorised valve/pump. The motorised valve cools down until the next time it is turned on.
The plumber/electrician who fitted it do not know what is wrong. Our only thought is the RWB programmer is not sending the off signal to the motorised valve, so should we go ahead and replace the programmer with a direct replacement RWB29 unit.
