Temperature Control Actuator
TEMPERATURE CONTROL ACTUATORINSPECTION
1. Verify that the temperature actuator operates to the hot position when connecting 12 V to the terminal 2 and grounding terminal 1.
2. Verify that the temperature actuator operates to the cool position when connecting in the reverse.
3. Check the voltage between terminals 3 and 4.
It will feed back current position of actuator to controls.
