I guess the next question is obvious. I am planning to use a Honeywell CM907 programmable thermostat. The central heating system has a condensing boiler, hot water tank, pump, and an older Drayton programmer which does not allow you to time the heating and hot water separately. I plan to keep...

Turned out to be a faulty pump which has been replaced under warranty. The replacment seems to be running well.

There are two diverter valves and the pump is wired directly to the boiler. The thermostat appears to be working fine as it is showing boiler demand at the appropriate temperatures. Measuring the voltage at the pump will be difficult with the type of connector they use, but I will try to...

I agree that they are the meanings of that error code but I do not understand why it runs OK and then there would be a voltage drop and recover when I switch it all off and back on. Same goes for the blocked pump, expecially when it is a new pump and the old one showed no sign of problems...
