Moisture level sensor - for use with C Series controllers only fitted with IRR-SPV2 pumps (2015 onwards)
This unit comprises a self install PCB that sits inside the controller case and is attached to the main PCB. The moisture sensor has a 5m cable - the sensor is intended to stop the irrigation is there is already sufficient water in the soil. It can be switched from wet to medium to dry if required, but it is recommended to start with the wet setting.
It is important to position the sensor correctly as if it is too close to the dripper it will lead to very short pumping times.
