Attn. Member in W.A who called, sorry to be vague when I first answered the phone, I'm currently having once again a rash of scamers.
My thoughts have reset and would advise that all my system inc the two sensors were in working order. (See previous posts with cct & impedances)
And be advised that once you fix the issue, the "resetting" of the computer can be very frustrating, it took me many goes to get it to reset.
