Custom ventilation control

A ventilation control macro is used to describe a custom ventilation control strategy for a zone.

See Custom control for general information about control macros.

The final output signal should be connected to the pre-defined interface reference OUTSIGNALLINK on the border of the macro. An output signal=1, means VAV air flow is at its maximum setting according to given parameters in Controller setpoints (provided the fan is running); output signal=0, means VAV flow is kept to min setting (Note: not normally zero). Supply and return flows are always controlled in parallel (but may have different min/max settings).

Note that the setpoints may be redefined in the central zone control.
