Can anyone recommend a good room thermostat, preferably a digital wireless one that can be moved from room to room? There must, however, be zero voltage on the connection to the boiler circuit board. As soon as the fitter saw that it needed to be 0 volts, he disappeared and has not been seen...

Hi - yes there are 4 connectors. 2 white wires, which I presume come from the switch, and a brown and a blue as the power supply. These are providing power to the timer, according to a voltmeter, so I cannot see where there could be a loose connection unless it is within the timer unit itself...

The timer, which incorporates the on/off switch, is a sealed unit. If there was a problem with the connection to the timer, then the on/off switch would surely have no effect either, and there is power going to the unit as I said.

The combi boiler is working fine, but the timer now doesn't. The timer unit is receiving power and the circuit board is fine, but the timer does not rotate. I have tried a new timer from the supplier, but with the same result. The On/Off switch that the timer would activate were it to rotate...
