Field Wiring

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. 57 Ð Wiring of the Duct

High Humidity Switch

The 24 vac power source(s) to both duct mounted and wall mounted relative humidity transmitters MUST be isolated. Connecting either side to a ground will per- manently damage the sensor.

The power for the relative humidity transmitters may be sourced from the valve 24 vac power source at wire no. 6 and 7 or at wire no. 4 and 5.

Connect the signal wires as follows: Secure one wire to the terminal labelled OUT 1 (located at the right of terminal block OUT). Secure the other wire to the negative signal output terminal (terminal adjacent to the terminal labelled OUT 1). Run the twisted pair of signal wires to the PIC control box. Observe all local code requirements.

Outdoor Relative Humidity Transmitter: Connect the posi- tive (1) wire to pin 31 of the processor module. Connect the negative (−) wire to pin 32 of the processor module.

Return Air or Space Relative Humidity Transmitter; Connect the positive (1) wire to pin 10 of the processor mod- ule. Connect the negative (−) wire to pin 11 of the processor module. See Fig. 61.
