Answer: It suffices to clean the valve together with the waste tank. It should be flushed after coming back from holidays.

Answer: Jes, however one should avoid this for environmental reasons. Dispose of your sewage only at the drainage points intended for this purpose.

Answer: No, the valve cannot open suddenly due to lower board voltage. Our circuit holds the valve closed if the tension drops. If the valve is open at a voltage drop, it closes if voltage is applied again. Emergency closure.

Answer: No. This would be a disaster when camping in winter. Furthermore the waste water should be disposed only at drainage points intended for this purpose.

Answer: No. Except for the situation that the children have the remote control in their hands and can easily close or open the valve. Your grandchildren will be glad. The valve is not controllable from outside without transmitter (only by means of emergency release at the valve itself!).

Question: How much cable do have to connect?

Answer: We have kept the control simple. We pre-connected the technics, so what is left for you are 2 cables, +12V and earth.

Answer: Jes. Pay attention that you do not switch the cable wires.

Question: Does the valve need "current", when it is open or closed??

Answer: No. We have a current saving version. You have "current consumption" only while the valve is opened or closed, when the valve is moving. Ball valves need no "quiescent current". The control itself needs only little mA standby current.

Answer: The remote control uses the ISM-BAND (Industrial, Scientific, and Medical Band), this is a frequency range for high frequency - transmitters in industriy, science and medicine which are not subject to governmental regulations. ISM-frequencies are internatioally assigned for use by means of high frequency devices.
