RELAY OUTPUT

Dual function Series DF models are designed to control two independent level
functions, one single-level control operation and one differential-level operation.

Optional Power Outage feature resets after nuisance outages. Optional Reset Button is
used when device has been deactivated due to low water condition. Reset is activated
only after water has returned to normal level. This control is ideal in applications on
boilers, food service equipment, and chemical delivery systems.
