HydroStatʼs low water cut-off function is active when the control is installed on a Hydrolevel Electro-Well. To test the low water cut-off function:
 Turn off power to the control.  Set the thermostat to call for heat.  Gently slide the sensor out of the well to simulate a low water condition.
 Re-energize power to the control. The red LOW WATER light should come on and the burner should not fire.  Turn power off again and rein-
stall the sensor in the well.  Re-energize power to the control. The green LWCO ACTIVE light should illuminate and the burner should fire.
MAINTENANCE
Remove the Electro-Well from the heating system every five years and clean any scale or sediment deposits from all parts that are exposed to
the boiler water. After cleaning, reinstall the well using pipe sealing compound. Teflon tape is not recommended.
