Temperature Sensor Replacement
The temperature component is a small sensor board located inside a plastic housing
(Figure 29). This will be mounted outside, typically either near the display or near a
building. If the temperature sensor is not working correctly, the internal sensor can
be replaced by accessing it as follows:
Tool required: Phillips screwdriver
1. Open the temperature sensor housing by removing the four nuts from the
bottom, and removing the five bottom discs. Three of the discs are solid,
while the center two have a square hole in them to fit around the sensor.
2. Label the wires connected to the temperature sensor board and then
disconnect the cable from the temperature sensor terminal block in the
sensor housing.
3. Remove the two screws holding the board to the plastic disc. Install the new
board, and replace the two screws.
4. Reconnect the cable to the temperature sensor board, making sure all the
wires make a good electrical connection.
5. Route cable around the sensor board (Figure 28)
and then reassemble the sensor enclosure.
