Pump control SHT 217 with acoustic alarm

The SHT 217 plug-in water detector functions as a pump controller. If the sensor detects soil moisture, the plug-in water detector activates the connected pump and an alarm sounds. After the sensor dries, the pump continues to run for a configurable run-on time of 0 to 100 seconds, then shuts off, and the alarm goes silent.

Functional description:

The SHT 217 is a plug-in pump controller that switches on a connected water pump when a certain water level is reached and switches off again after an adjustable run-on time of 0 to 100 seconds once the sensor has dried. An acoustic and visual warning signalizes the presence of water. A safe and defined shutdown behavior can only be achieved with a mini float switch ( SHT 227 ).

Extension sensor cable:

If necessary, you can extend the sensor cable up to 50 m using a 2 x 0.14 mm² cable. To do so, you must cut the existing sensor cable and reconnect it with terminals.

Without acoustic alarm:

The same device is available as pump control SHT 218 (Art. No. 300218) without acoustic alarm.

Use with non-conductive liquids:

For other liquids such as heating oil, diesel, vegetable oil, lubricating oils, etc. you need the SHT 227 device (item no. 300227) with float switch.

The LIYY cables are only temporarily waterproof and, according to the manufacturer, are flame-retardant, low-adhesion, self-extinguishing and largely resistant to oils, greases, coolants and lubricants.

Use of water sensor in the pump sump (condensation water):

Use the SHT 227 device (Art. No. 300227) with mini float switch if the device is used for cyclic operation.
