Function
The product contains a changeover contact. If the water level in the boiler
drops below a minimum level, a switch deactivates the power supply to the
burner. The contact can switch additional equipment (for example, a horn).
The test unit allows the float to be lowered to simulate a low water alarm con-
dition.
Product with locking
A locking mechanism keeps the burner from restarting automatically.
Product without locking
A product version without unlocking mechanism is also available for unlock-
ing and resetting directly from the control cabinet.
