I tried everything. Breakers and switches are ok. The boiler is also
fine. I checked the voltage in the heatlink, there is. Turned off the
heatlink for a few minutes. Nothing happens when I turn it on. No
reaction after press the button.
I have exactly the same problem as John and RobG. After 20 months the
heatlink is broken, 240 volt is there, but no lights. Reset does not
help. Is there any chance to fix this?
