The prerequisites for the humidifier activating the CV valve actuator to make steam are as follows:

The Humidifier will undergo a self-test when the power is turned on activating the and other
internal components followed by a float test.

If the above listed prerequisites are fulfilled the humidifier will fill the tank, open the CV valve and
begin normal operation.
