[FIXED] Possible OTG failure ?

[hvxl]

I opened up a T87M1003 and the solder pads for the hot water button of the T87M1011 are actually there. With a bit of fiddling with a piece of wire to make an electrical connection between the two pads, it's possible to switch off the hot water setting (crossed out tap appears on the display). However, after briefly disconnecting and reconnecting the thermostat it's back to normal again.

Update: I succeeded, the boiler of indicator is off
