Lag time of the central boiler or cooling unit.
What is this? The time required by the central boiler or cooling unit to stop heating or cooling.
Why is this necessary? To release residual heat or cold.
The control valve for the zone will remain open for the time selected to allow the
central boiler or cooling unit to release its residual heat or cold.
