ELECTRONIC LOW WATER CUT-OFF, PROBE TYPE

for Steam Boilers Residential and Commercial Applications with Self-Cleaning Probe

An inexpensive direct mount solid state control which uses the conductance of the boiler water to sense water level and shuts down boiler operation until level is restored. A 10-second timing feature allows for normal water turbulence during normal boiler operation and eliminates nuisance shutdowns.

Automatic reset allows boiler operation to resume as soon as water level comes in contact with probe (manual reset models are available on special order). LED low water indicator lamp shows when control is in low water shutdown mode. A separate terminal is provided for use with a 24 volt alarm or with a WF-2-U-24 water feeder.
