KATSU Automatic Water Pump Pressure Control Switch 220V IP54 Electronic Adjustable Uper and Lower Pressure Controller, for Garden Pumps, Clean Water Pump 151019

To answer a question here on wiring I've simply looked at my existing installation. Remove four screws on the front panel to reveal the wiring to the electronics. You see two sets of three wires - the top three are the 240v mains supply - from the top to bottom they are LIVE/brown or L1 then NEUTRAL/blue then earth/green. The bottom three go to the pump, starting at EARTH then U (eg brown) and finally V (eg blue). Note that N or neutral is connected internally to V. The device switches the power to terminal U. Thus if you wanted to override the Katsu you can connect L1 to U and your pump will operate uncontrolled.

Works well but cannot be commissioned properly until a replacement pressure gauge is fitted

Swapped for existing in 15 minutes.

Hi I would to request the item I purchase because its damage the meter cover. I send a picture of a broken meter cover.

Still works (after 1 month). Due to our situation we need to press the reset button regularly. I which it would haver some kind of auto-reset function.

There's no wiring instructions, how do I connect it.

Es war alles wie vom Verkäufer beschrieben!! Super!!

Bom produto. Instalei numa electrobomba para rega, para substituir um balão. Ter atenção nas ligações electricas, não trocar os polos. Ficou a funcionar perfeitamente.

Fonctionne sans problème

Parfait fonctionne bien
