Weather Station Electronics Board, Connect Secondary Sensors (Commercial Model)
The Pyranometer sensors are not interchangeable. The secondary sensor must be wired to
Pyranometer #2.
The PV sensors are not polarity sensitive. Therefore, each signal wire is interchangeable. The sensor
comes with a 25ft length of cable. If a temperature sensor is not used, it should be terminated with a
0-ohm shunt between the positive and negative signal.

Connect PV Panel Sensor (Entry Model)
If you are not planning to connect the PV panel temperature sensor, skip this section.
1.
Attach the PV panel temperature sensor so it registers the temperature on the backside
of a PV panel. See
Sensor Mounting Requirements
for location and mounting
considerations.
2.
Connect the sensor to the proper location on the circuit board. Note that the PV
