62-0208—3

Fig. 4. Humidity Sensor (0-10 Vdc output) wiring with T7350

 (use with RH/Temperature combination T7350 units only).

Fig. 5. Typical wiring diagram for 5-wire temperature/humidity sensor with Vdc output 

(used with the XL15A controller).

POWER SUPPLY.  PROVIDE DISCONNECT MEANS AND OVERLOAD PROTECTION AS REQUIRED.

ENSURE TRANSFORMER IS SIZED TO HANDLE THE LOAD.

HEAT/COOL SYSTEMS WITH ONE TRANSFORMER REQUIRE THE FACTORY-INSTALLED JUMPER.

USE ECONOMIZER INSTRUCTIONS FOR INSTALLATION DIRECTIONS.

HC AND HP PROVIDE 24 VAC TO THE HUMIDITY SENSOR.
