Hardware
MM9A - Irrigation controller for MM8D
The device has three control inputs, three 24V DC valve outputs, one 230V AC pump output and two pressure fault relay contact outputs. To activate the inputs, the auxiliary voltage must be connected to them. When any input is activated, the pump output also turns on. If the water pressure exceeds the set value (eg clogging), the pump output is switched off and the >Pmax output is switched on. If the water pressure falls below the set value during operation (eg lack of water), the pump output is switched off and the <Pmin output is switched on.
