User Manual GS21RZ03 version 1.5 Rockwool BV – Grodan is part of the Rockwool Group. Industrieweg 15, 6045 JG Roermond, the Netherlands www.grodan.com 2 Introduction The GS21RZ03 (Rootzone sensor) is part of the Grodan GroSens sensor platform. This sensor platform enables growers to read out climate and root zone information from their growing rooms and view this data in a mobile phone app or in graphs on their desktop or laptop. The GS21RZ03 has been certified for the European (including Turkey), USA and Canadian markets. Onboarding For onboarding the sensor in the platform, please download the “Companion” App from the Apple App Store or Google Play Store. Follow the instructions in the app to configure and connect the sensor. User Manual GS21RZ03 version 1.5 Rockwool BV – Grodan is part of the Rockwool Group. Industrieweg 15, 6045 JG Roermond, the Netherlands www.grodan.com 3 Placement Position in the substrate Picture 1A and 1B show the correct placement of the sensors in the substrates:  Place the sensor 8-10 cm to the left of the 2 nd block from the water drain hole  Sensor should be positioned closer to 2 nd than to 1 st block, ideally at 2/3 of distance towards second block. If blocks are close to each other, the minimum distance is 5 cm between sensor and block. Picture 2A and 2B show placement of the sensors, in case the substrates is on a slope  Place the sensor at the lower side of the slope in the substrate Adjustment for different substrate thicknesses The support plate at the back of the sensor can be adjusted with the screw to one of the four different positions. Each position is optimized for the indicated substrate thickness: 7.5, 8.5, 10 and 12 cm. The substrate thickness can be read through the window in the support plate. Note: the 7.5 cm position is not visible in the picture as it is behind the alignment plate.   User Manual GS21RZ03 version 1.5 Rockwool BV – Grodan is part of the Rockwool Group.
