Irrigation valves in the fertigation system Hydria 4+ Touch are a lot more than just simple relay outputs. Each irrigation valve is an individual component controlled by numerous parameters. The following can be defined for each valve:
1. The maximum injection percentage of the nutrient and acid valves. This happens for safety reasons, but also for an even more reliable operation in cases of high heterogeneity in the irrigation supply. What does this mean in practice? It simply means that under no circumstances will the nutrient valves operate in full capacity, if we know for example in advance that this is not required for the given supply of this specific valve. In this case, this is a parameter that we can include in the operation safety settings of the machine. These safety limits are also particularly useful under conditions of very low supplies, in which they reassure that no fluctuation in the EC and pH values will occur.
2. Which pumps will be supporting each irrigation valve ( Hydria 4+ Touch supports one main and unlimited auxiliary pumps).
