ALARM BOARD CONNECTIONS

FOR NORMALLY CLOSED "NC" OPEN-ON-ALARM STRATEGY

IMPORTANT

LED display board is shipped loose to protect it from possible damage during

installation of the wiring to main controller board and/or the alarm board. It is polarity

sensitive and is keyed so it can only be installed in correct position.

Note 1:

2nd Stage, Econ 1, Econ 2, High Temp 2 and Controller alarms are only on -B

alarm board. All other alarms are on both -A and -B alarm boards.
