Ok, due to not knowing what is the thermostat circuit, I will go the DPDT
way, like it was suggested by Dick Tasker.
Thanks Dick, don't we know each other from the Subbie group?
Cheers
Carlos

Dick Tasker, right you are. The manual warns against connecting power to
the temperature controller output. At least I think it says that. It is
hard to read Chinese. LOL Without having the controller circuit board in
hand along with a schematic, an informed decision can not be made. Dick's
suggestion about using a double pole double throw (DPDT) switch is the safe
way to wire it.

| Subject: | Dynon Pitot Heat Warning with MGL EFIS |
Folks,
I am installing a Dynon heated pitot tube. The controller has a pin which
gets grounded if the heater is turned on and fails. This is supposed to
drive a warning lamp. See "pitot heat warn" on the attached diagram.
I want to replace the pitot heat warn lamp with an indicator on my MGL
EFIS. The EFIS has eight analog inputs (see A1 through A8 on page 6 of the
attached iBOX V1 installation manual) and also has four balanced analog
inputs (see 1+,1- through 4+,4-) on page 7.
This would be easy for me if INST-4-G from the Dynon controller was either
grounded or at some positive voltage. But if I understand correctly, that
wire is either grounded or open. How do I hook this to my EFIS?
Thanks,
-- Art Z.

Connect a pull-up resistor, perhaps 1K or more, between a positive source and
the Dynon alarm wire.

Joe,
What do I connect to the EFIS?

I would try it without the pull-up resistor first. It might not be needed.

How would you do that if the reference is ground?
