The control system
Control box
The plastic box with the big sticker on the front is the control unit that is the brains of your
Harvster. It fixes on the right hand side, just under the lid. Screw it to the back panel with
any short self tapping screws.
Power (mains)
If you have a mains powered Harvster, it will come with a power supply already wired into
the control unit. Run the mains cable through the notch in the base of the right hand panel,
and across your yard to a suitable power point.
Power (solar)
You’ll have a solar panel which needs to be positioned somewhere that will get as much
sun as possible throughout the day. It can be up to 3 metres away from your Harvster.
Mount it securely, and run the cable into your Harvster appropriately based on where
you’ve mounted the solar panel.
Soil sensors
Your Harvster comes with two black dual-purpose sensors, which will measure soil
moisture as well as soil temperature. These are best placed in an area where the
temperature and moisture doesn’t change too fast; such as a large container of soil, or the
ground. It’s best placed horizontally, just under the surface.
The first soil sensor is what drives the irrigation (and optional heating) for zone 1. The
second sensor (with the red band around it), is used to monitor zone 2. We recommend that
the top shelf is one zone (watered by the mister bar) and the bottom of your Harvster is the
second zone (watered by the sprayer bar).
The soil sensors plug into the 4-pin connector on the control unit, via a Y-splitter. Do not
plug or unplug while the control unit is turned on.
Air temperature sensor
A silver temperature-only sensor comes pre-wired into your control box. You can use this
to monitor any temperature; typically it’s used for outside air temperature, and will show as
“air temp” on the app.
