Standard Application
Safgard 1100 Series Controls are used as the primary low water cut-off
device on residential hot water boilers.
Operation
Hydrolevel controls utilize a non-moving, heavy duty, electronic probe to
sense liquid levels. The probe can be installed in an equalizing line or
directly into a boiler or water tank in accordance with manufacturers
instructions and local and State codes. When water is in contact with the
probe, it completes a circuit between the stainless steel probe tip and the
tank or boiler surface in which the probe is installed. When water level
drops below the probe, the circuit opens. Hydrolevel low water cut-offs for
hydronic heating systems use the water signal to allow the burner to operate.
If the water level drops below the probe, the circuit opens and the cut-off
shuts down the burner.
Automatic Reset - Shuts down
the burner when water drops
below the probe. Automatically
restores the burner circuit upon
return of a safe water level.
More Probe Plate Space -Large
probe tip puts more conductive
surface in the water, leading to
more dependable operation and
less chance of nuisance boiler
shutdowns.
Compact Size - Designed to fit
in tight spaces.

fast and easy.
