NOTE: Connections for 39NX with integral PIC shown. See wiring diagrams in Fig. 9 and 12 for terminal connections in 39L control box and all remote-mount control boxes.

Fig. 16 Ð Chilled Water Valve Wiring

Space Temperature Sensor (Fig. 18) Ð The space temperature sensor (SPT) is packaged and shipped inside the fan section. It is installed on a building interior wall to mea- sure room air temperature.

The wall plate accommodates both the NEMA (National Electrical Manufacturers' Association) standard and the European 1¤4 DIN (Deutsche Industrie Norm) standard. The use of a junction box to accommodate the wiring is recom- mended for installation. The sensor can be mounted directly on the wall, if acceptable by local codes.

DO NOT mount the sensor in drafty areas such as near heating or air conditioning ducts, open windows, fans, or over heat sources such as baseboard heaters or radiators. Sensors mounted in these areas produce inaccurate readings.

Fig. 17 Ð Duct Static Pressure Probe

Avoid corner locations. Allow at least 3 ft between the sensor and any corner. Air¯ow near corners tends to be re- duced, resulting in erratic sensor readings.

The sensor should be mounted approximately 5 ft up from the ¯oor, in the area representing the average temperature.

Install the sensor as follows:

1.Remove sensor cover. Using a small blade screwdriver, insert blade into sensor cover latch slot on bottom of slat. Gently push upward on the screwdriver to release the cover latch. Rotate the cover forward as the screwdriver is re- moved.

2.Snap off the wall plate from the base assembly.

3.Feed the wires from the electrical box through the sensor base assembly.

4.Using two 6-32 x 5¤8-in. ¯at screws, mount the sensor base assembly to the electrical box.

5.Dress the wires down and inside the perimeter of the sen- sor base.

6.Attach the wall plate by snapping it onto the sensor base assembly.

7.Replace the cover by inserting the top inside edge of the cover over the tab on top of the sensor base assembly and rotating the cover down. Snap cover on.

Refer to Field Wiring Connections section, page 52 for wiring instructions and details. See Table 3 for Thermistor Resistance vs. Temperature Values.

NOTE: Clean sensor with damp cloth only. Do not use solvents.
