Hi,
I have a Vaillant TurboMax Boiler a Danfoss 103 mech timer and the standard Honeywell thermostat.
About a year ago the boiler no longer responded to the Timer instructions, it still works when the timer is switched to constant and the heating responded to the thermo. So I wasn't that fussed about it.
Anyway, the other day I replace the Danfoss with a Wickes 7 day programmer and that works (i.e the digital timer is on!) but now the boiler doesn't respond to the thermo stat.
The programmer still doesn't effect the boiler.
However, I can still get hot water
Any idea where the problem may lay.
Cheers!!!
