Note 2: The Proportional Gain parameter depends on the number of configured heat stages for proper algorithm
performance. The HI will automatically adjust this parameter to the proper setting defined below if it detects the
incorrect value for the number of configured heat stages. If heat stages are not configured it will place 30 %/F in the
field as a default until heat stages are configured. This will happen once at power up if needed and applies to all units.
