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.
Field Wiring
NOTE: The relay furnished is a SPDT relay with silver cadmium oxide contacts, rated as follows:
48 va at 24 vac and .25 power factor
125 va at 115 vac and .25 power factor
125 va at 230 vac and .25 power factor

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.
