Hi,
Would appreciate some advice. Have attempted to replace my thermostat with a different type (Honeywell THR840DUK). The new one whem fitted kept blowing the fuse.
I have re-instated the Satchwell wiring as it was when I removed;
Terminal 1 - Blue
Terminal 3 - Brown
Terminal 4 - Green/Yellow
Back Plate - Bare Earth Wire
When I turn the thermostat up to kick-in the boiler/heathing the fuse keeps blowing.
Any assistance would be much appreciated.
Kind Regards,
