.Buildings.Templates.Components.Controls.StatusEmulator

Information

This block emulates the status of an equipment, i.e., the current on/off state as reported by the hardware itself.

The status is off at the start of the simulation. This is hardcoded and cannot be modified.

The delay between the on command and the on status is the same as the delay between the off command and the off status. This delay can be adjusted with the parameter delayTime.

Note that the default delay may not be representative of the actual dynamics of certain equipment such as chillers or heat pumps. In addition, this block uses the equipment command signal to generate the status signal, which in turn can lead to inconsistencies with certain equipment that run cyclically at low load, despite being steadily commanded on. In such cases, the actual status comes and goes, whereas the status computed with this block will remain continuously on.
