HI TEMP
TTL compatible logic signal provides warning
when unit approaches thermal shutdown.
FAN FAIL
TTL compatible logic signal provides warning
when fan speed is inadequate to cool unit.
INHIBIT
TTL compatible system inhibit provided.
PILOT BIAS
+5 VDC @ 0.5 Amps.
ENABLE
Enable pin must be shorted to Common for
proper operation.
