USE 18 AWG WIRE MINIMUM. TO MINIMIZE
INTERFERENCE PROBLEMS:
USE SHIELDED WIRE ON ALL ANALOG INPUTS
AND OUPUTS. DO NOT RUN 0‐10 VOLT DC
SIGNAL WIRING IN THE SAME CONDUIT AS
LINE VOLTAGE WIRING OR WITH WIRING
THAT SWITCHES HIGHLY INDUCTIVE LOADS
SUCH AS CONTACTOR AND RELAY COILS.
GROUND ONE END OF THE DRAIN (SHIELD)
WIRE.
WHEN 0‐10 VOLT DC SIGNAL WIRING MUST
CROSS CLOSE TO CABLE OR NONMETALLIC
CONDUIT CONTAINING LINE VOLTAGE
WIRING OR WIRING THAT SWITCHES HIGHLY
INDUCTIVE LOADS, IT MUST CROSS
PERPENDICULAR (90 DEGREES) TO IT.
KEEP THE 0‐10 VOLT DC SIGNAL WIRING AS
SHORT AS POSSIBLE.

Note: THE SUPPLY/DISCHARGE AIR TEMPERATURE/RELITIVE HUMIDITY
(SA‐T/RH) IS FACTORY SUPPLIED FOR FIELD INSTALLATION IN SUPPLY AIR
DUCT. SENSOR MUST BE INSTALLED DOWNSTREAM OF HEATER WHERE
IT CANNOT “SEE” ANY HEATING ELEMENTS AND WHERE SUFFICIENT
MIXING OF DISCHARGE AIR OCCURS. USE 18 AWG SHIELDED WIRE. DO
NOT RUN SENSOR WIRING IN THE SAME CONDUIT AS LINE VOLTAGE
WIRING OR WITH WIRING THAT SWITCHES HIGHLY INDUCTIVE LOADS
SUCH AS CONTACTOR AND RELAY COILS.
