This switch ensures that your pump is not on unnecessarily and is only used when necessary. To do this, you only need to connect it to the circulation pump and supply line. It then provides your circulation pump with an on/off switch. This Eco pump switch from Wentzel is specially designed for underfloor heating manifolds, because the underfloor heating does not have to run continuously in the warmer summer months. If you switch off a circulation pump completely in the summer months, the pump can get stuck. You do not have to worry about this with this pump switch. Thanks to the 24-hour cycle function, with which the pump switch runs your pump once every 24 hours, the pump switch prevents the pump from getting stuck. The pump switch will therefore benefit the lifespan of your circulation pump. The Magnum Eco pump switch comes with a clip sensor. If you connect the clip sensor to your warm supply line, you enable the pump switch to unlock additional functionalities. As soon as the water temperature of the supply line rises above the set temperature, your connected circulation pump will be switched on. When the temperature falls below the set temperature, the pump will be switched off. The Magnum Eco pump switch has a frost protection that comes into operation when the temperature falls below 5°C. The pump switch has very clear symbols and function keys and comes with a simple installation manual.
