Communication Error H74

Open Skol6 opened this issue 9 months ago • 7 comments

Hi Folks,

Heishamon was running for several weeks without any issues. during the last days I got multiple times commincation error H74.

Not nowing what could be the problem I have performed a complete power cycle of my aquarea heat pump. Afterwards everything is running normal again.

Can someone confirm this issue?
