Hi All,
I've followed the Y-plan with pump overrun and direct live for the boiler but still the CH and HT not working.
I Have;
Worchester Greenstar RI
Honeywell ST9400
Honeywell DT90E
3 Port Motorized Valve
The boiler is on standby, thermostat ok and control panel ok. But when I put CH or HW on, nothing happens.
Any help would be great!
Thanks,
Greg
