Why can't SCC-sg24 be used as a first stage in a dual stage system as documented

[storeytime]

So it doesn't get lost in the original message,

Is there a AIGND on the screw terminal block?

Hi storeytime,

As you saw, page 2-2 of the SC-2345/2350 Carrier User Manual shows that there is no connection to AI GND on the terminal block.

To get to AI GND you can use the SCC-FT01 module as mentioned in this last post of this thread.

Have a great day!
