Potterton Netaheat 80E DHW but no CH

by PaulRen » Tue Jan 04, 2011 1:52 pm

Hi
Potterton Netaheat 80E Boiler. Fires up ok for DHW but nothing happens when CH is demanded. CH controller light comes on and don't think it is the room thermostat as I bridged it out and nothing changed.
Any ideas?
Mercury vapor valve?
Capacitors on PCB?

Cheers.
