.Buildings.Examples.Tutorial.CDL.Controls.Validation.EquipmentOnOff .Buildings.Examples.Tutorial.CDL.Controls.Validation.EquipmentOnOffValidation model for the equipment on/off controller. The input to the controller is a ramp signal of increasing measured boiler water temperature, and a on/off signal for the overall system. The validation shows that the pumps are on/off based on the overall system, and the boiler is also on/off based on this system unless the return water temperature exceeds 90°C.
