• The controller has a
form C contact for
remote enunciation of
temperature sensor
failure and low/high
temperature alarms.
If an external alarm is
required, then alarm
wiring can exit the
enclosure via the 3/4 in
power conduit hole as
long as the insulation
rating of the alarm wire is
equal to the power wire.
Normally energized; changes state upon an alarm.
