[FONT="]Hi everyone. I have traced out the wiring today and believe that my boiler is permanently outputting a "1" "call" to the Cylinder stat despite not being enabled by the on board programmer. This means the tank stat permanently sees a "live" and (if cold enough) holds the valve open permanently. The system is working fine apart from this anomaly. I have the DHW side of the programmer set for 3 x half hour slots per day and I would have expected the programmer to determine when the boiler (X1 L) goes live?[/FONT]
[FONT="]My major concern is that the tank valve is being held open 24/7 and may take the motor out?[/FONT]
[FONT="]Any help or advice gratefully received.[/FONT]
[FONT="]Cheers,[/FONT]
