Buildings.Templates.Plants.Controls.MinimumFlow.Validation.Controller
Validation model for the minimum flow bypass valve controller
Information
This model validates
Buildings.Templates.Plants.Controls.MinimumFlow.Controller
in two configurations: one where the bypass valve controller is enabled
with the isolation valve command (component ctlFloMinVal), and
another where it is enabled with the primary pump status (component ctlFloMinPum).

Buildings.Templates.Plants.Controls.MinimumFlow.Validation.ControllerDualMode
Validation model for the dual mode minimum flow bypass valve controller
Information
This model validates
Buildings.Templates.Plants.Controls.MinimumFlow.ControllerDualMode
for cooling-only (components *Coo), heating-only (components *Hea)
and heating and cooling applications (components *HeaCoo),
and for two plant configurations: one where the bypass valve controller is enabled
with the isolation valve command (components ctlFloMinVal*), and
another where it is enabled with the primary pump status (components ctlFloMinPum*).
