new thermostats to York control board

Hi,
I am brand new to the forum, and thanks in advance for any input and help.
I have a project installing Pelican TS200 internet programmable thermostats for a number of York model #D1HG060N07925BDA packaged rooftop units. These new thermostats require a common for power, and are replacing battery operated thermostats.
The issue is verifying the common connection on the York # 031-00880-001 control board.
I hooked the common to the terminal labeled "B" on the control board (blue wire in attached photo).
The thermostats power up, but the heat trips out and has to be reset each time.
Would anyone know where the Common wire should connect on this control board?
Is "B" the common?
Is the heat trip related?
Thanks,
Henry

    If you can't find a schematic for the unit on the internet, you should be able to land it under one of the support screws.

    I found a low voltage stat wiring diagram online and it showed B as common.
