Hello,

I just recently changed the processor on this thermoking, but I'm still getting code #77. I was told I needed to do a factory reset and to do that i needed to go into guarded access. Thing is I don't know how to enter guarded access. I have looked everywhere to no avail, if anybody knows the steps on how to enter guarded access I would be very thankful!

This is the control panel that I have, except it has the T logo button where the one on the picture has a button missing.
