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.
