Hello
Attended a property where a local boiler care company have attended a fault with the heating and have replaced the stat and then traced a fault on the programmer (Drayton Tempus 2).
However the engineer refused to change the programmer as in his words 'there is a wiring fault, voltage present on neutral when boiler is isolated'
He has 'bypassed' the timer so the heating is constantly on. Upon testing this I found that when the boiler is isolated there is no voltage on any of the wires at the programmer. When the boiler is turned on there is a backfeed of approx 20v from the live switch wire to the boiler. I assume this is just leakage from the PCB/components within the boiler and is unlikely to have caused the demise of the programmer.
Shorting the live feed to the programmer with this live switch wire fires the boiler up as expected so do you think the fault is simply a dodgy switch within the programmer itself?
