## Description

STAK Enterprises' Hydro Check Model HC4000 Tank Level Controller Control the level of water in a tank between maximum and minimum levels. Maintain proper water levels in aquariums, landscaping ponds, waterfalls, water sculptures, etc. The HC4000 has two sensors, one to control the high fill point and one to control the low fill point. This electronic controller works with all brands of pumps, like Flotec, Simer, Wayne, Ace-in-the-Hole, Rigid, etc. Simple Installation: The Hydro Check Model HC4000 Tank Level Controller has two sensors and a control module. Control module plugs into a 120 VAC outlet The pump plugs directly into the control module. Place one sensor in the tank at the minimum water level. Place the other sensor higher in the pit at the maximum fill level. The HC4000 controller doesn't care which sensor is the upper sensor, and which one is the lower sensor. It figures that out automatically so the operation of the pump is always correct. Test by running through acomplete cycle How the Tank Level Controller Works: The setting of the sensors determine when the control module turns the pump on, and when it turns it off. Following the sequence below, the operation is as follows: 1. When both sensors are detecting water, the pump is off 2. When the water drops between the two sensors the pump stays off 3. When neither sensor is detecting water, the pump is turned on 4. The pump stays on while the water is between the sensors 5. The pump is turned off when the water reaches the top sensor How the Sensor Works Water is detected by use of a continuity circuit, i.e. when the sensor tip is in water, a small voltage flows from the sensor through water to ground. When no water is present the circuit is broken and no voltage flows. Typically, the pump provides the ground. If it doesn't, take a length of 14 AWG wire, strip off a couple of inches of insulation at both ends. Secure one end of the wire around a water pup or electrical conduit. Place the ot
