* If an extension card is installed, the inputs for Ultrasonic 5µS/cm and Aux2/fire are situated
on the extension card.
The sequencing uses the standard inputs for Remote on/off and Aux1/water detector and the standard
outputs for reheat 2 and the common alarm.
If the input for Aux1/water detector and/or the output for reheat 2 are required, an extension card must be
installed, which provides an input/output for the sequencing.
This way the water detector input and the output for the 2nd reheat are provided on the processor board
again.
