blockCoolingCoil
Controller for cooling coil valve
Information
This block outputs the cooling coil control signal if the fan is on and the zone is
in cooling status (see
Buildings.Controls.OBC.ASHRAE.G36.Types.ZoneStates).
Otherwise, the control signal for the coil is set to 0.
The implementation is according to the Section 5.18.5.3 of ASHRAE Guideline 36, May 2020.
