The E.X.HTF Complete Solution is completely protected against lack of water in the well or in the tank. In case of dry running the ZDS Master 3 control panel stops the pump and a light starts flashing to inform the user that there is no more water in the well.
The E.X.HTF Complete Solution is completely protected against overload. In case the pump is partially or totally blocked, the ZDS Master 3 control panel stops the pump and a light starts flashing to inform the user.
The E.X.HTF Complete Solution is protected against low or high voltage, that can damage the motor. Low voltage can occur, for example, if the section of the power cable is not adequate considering the motor power and the distance between the plug and the pump itself; or if a generator is faulty or undersized for the pump. High voltage can occur with unstable supply network or with a faulty generator. To avoid potential damages, the Master 3 control panel restarts the pump when the correct voltage is restored.
In case of leaks in the piping system (also when the pressure tank is exhausted or its membrane is defective, or when there is a defective pressure switch) and too frequent starts and stops (i.e. if the tank is too small for the system), ZDS Master 3 control panel automatically stops the E.X.HTF Complete Solution and a light starts flashing to inform the user.
Any operation in the electrical circuit, the starting of different motors connected to the same network at the same time, possible surges in the network or an inadequate power generator, could modify the power supply damaging the pump. ZDS Master 3 control panel protects the E.X.HTF Complete Solution against voltage peaks caused by potential electrical abnormalities in the supply network .
The E.X.HTF Complete Solution is protected against phase-loss (caused by a brake of a fuse), as it protects the motor from damaging.
