FOR NORMALLY OPEN "NO" CLOSE-ON-ALARM STRATEGY

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.

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.
