WMS-WP6
4.4 Function
The product is a mechanical boiler water low level alarm with a float system
for sealed heating systems to protect the boiler. If the water level in the boiler
drops below a minimum level, a float activates a switch. This switch interrupts
the power supply to the boiler. A locking mechanism keeps the burner from
restarting automatically. The test button allows the float to be lowered to sim-
ulate a low water alarm condition.
A product version without unlocking mechanism is available for unlocking and
resetting directly from the control cabinet.
As per EN 12828, systems with more than 300 kW must be equipped with
water level limiters. However, the installation of such units is recommended
for all systems, in particular for roof heating centres.
The product is suitable for continuous operation.
