VA900 is developed to growers who wish to have a total overview of the irrigation process.
A rotary switch and a distinct display offer a good layout of the settings, which are simple and quick to make.
The irrigation controller has 3 groups, each offering optional combination of 7 different start conditions. One of the start conditions is a week program, in which you for every day may start the valves at up to 28 fixed times per week.
All 3 groups can contain up to 10 valves. If a valve is not going to irrigate as often as the others, it can be switched off without having to delete the settings. This makes the VA900 very flexible to use.
The irrigation controller has an alarm for sensor failure. In case of an alarm, the alarm output in the irrigation controller will be activated, and the alarm text will be shown on the display at once.
The VA900 is a product in the 900-Series and can be connected to other climate- and irrigation controllers. This gives the opportunity to read status on any 900-computer connected in the greenhouse.
VA900 can start any AMI fertiliser mixer, to control several fertilizer recipes.
