Comes with a special check valve (to protect against risk of water hammer).
Designed for controlling and protecting pumps in plumbing
installation or garden systems, irrigation, sports facilities, etc.
This electronic unit allows :
• Starting the pump with minimum difference in water pressure (opening of a tap), thus avoiding continuous
switching on/stopping of the pump.
• Automatic stopping of the pump after using the water (closing of tap)
• Protecting the electric pump against water supply failure: pump stops after 8 seconds of operation
• Protecting the system against risk of water hammer thanks to the built-in check valve
• Easy reading.
