Additional Information
The HydroCheck HC6000v2 Electronic Sump Pump Float Switch with Hi-Lo Dual Sensors and Built-in Alarms is a universal float switch that works with all types of sump pumps. Unlike other float switches that have a small or fixed range, the HC6000v2 is highly adjustable with 12ft sensor cables that provide the user with complete control of where the pump turns on and turns off. Built-in alarms will alert you if there is a problem with the pump or the discharge plumbing.
 
No moving parts in the pit ensures reliability. Sensors do not need to be cleaned and work in water with high iron or high mineral content when paired with our Installation Kit. The HC6000v2 is a versatile, heavy-duty switch that is rated for 1 HP, 15 Amps and can be used in hydroponics, aquariums, rain harvesting, etc.
 
The built-in anti-airlock feature will make 2 attempts to clear an airlock by shutting the pump off briefly if the sensor is still detecting water after the pump has run for 20 seconds.
 
How It Works
The placement of the sensors determine when the control module turns the pump on, and when it turns the pump off. Following the sequence below, the operation is as follows:
 
When the water is below both sensors, the pump is off.
The pump is off when the water is above the Black Sensor (Lo-Sensor), but hasn't reached the Red Sensor (Hi-Sensor).
When the water reaches the Red Sensor (Hi-Sensor), the pump is turned on.
The pump stays on while the water is between the sensors.
The pump is turned off when the water drops below the Black Sensor (Lo-Sensor).
