Netro Spark valve testing

How does the Spark test the valves?


I want to connect a 24V input sensor on the spark outlet channels to switch 2 knx connect valves in different location. Cabling to those valves is to long for 24V. 
The valve testing always says that there is not current and switch it off --> Do i need a resistor on the outlet to simulate a valve? If yes, which value should the resistor have?


Thanks,

Peter

Dear customer,


You can use an external multimeter to measure the resistance of the water valve. Before measuring, ensure that the wires connected to the water valve and the common wire are disconnected from the controller. If the resistance is greater than 100 ohms, this indicates an open circuit. Conversely, if the resistance is less than 20 ohms, it indicates a short circuit.
