0. Preparation
OSPi 1.4x comes with a laser-cut acrylic enclosure. Enclosure assembly instructions can be found in this
. You can do so either before or after the following setup steps.
●
From version 1.44, the real-time clock (RTC) and battery have been removed.
●
If terminal blocks are pre-installed, you need to first remove all terminal blocks before assembling the
acrylic enclosure.
●
In some kits, the acrylic pieces may be replaced by 3D printed versions (*this is due to shortage of acrylic
supply that occurred during the COVID-19 pandemic).
1. Test Power Supply First
Make sure the sprinkler transformer is unplugged to begin with. Insert the sprinkler transformer wires into the
orange
terminal block, tighten the terminal block screws. Then plug the orange terminal into the matching terminal on OSPi. The
green LED should light up, indicating power is on. See pictures below.
Warning: if the LED doesn’t light up, please unplug the power immediately. If you can’t figure out the problem, contact the
support at
