blockAssertMinimumRuntime

Assert that polyvalent heat pumps are not short cycling

Information

This block asserts that each polyvalent heat pump does not short cycle, based on its heating and cooling on/off commands.

If use_runTim=true (default), it asserts that each mode command remains true for at least dt_min before it turns false.

If use_runTim=false, it asserts that each mode command remains false for at least dt_min before it turns true.

Type	Name	Default	Description
Boolean	use_runTim	true	Set to true to assert minimum runtime, false for minimum off time
Integer	nUni		Number of units
Real	dt_min	10*60	Minimum runtime or off-time
String	message	if use_runTim then "Polyvalent HP minimum runtime is not met." else "Polyvalent HP minimum off-time is not met."	Warning message

Type	Name	Default	Description
