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.
WHEN USING THE TR23-H FOR HUMIDITY SENSING THERE IS NO NEED TO WIRE HC TERMINAL
BECAUSE THE T3 TERMINAL IS INTERNALLY TIED TO HC, WHICH IS ALSO TIED TO TERMINAL 1
COMMON AT THE SENSOR.
