Hi,
I recently changed a faulty PCB due to the boiler keep locking out when ch or hw were called for.
After changing it and the boiler firing up for h/w i forgot to check the ch. 2 months on its getting colder and what do you know, No ch.
Anyone got any ideas what this could be? I'v tried removing the programmer to cross that off, still same problem, tried spare pcb same problem.
The boiler is not locking out or giving any error codes. programmer is on, stat click, boiler makes no sign at all to call for heat.
Anyone had this before?
Thanks in advance
