-allows the boiler to perform as a space or DHW
heating boiler. DHW always has Priority and will override (steal) a
space heating boiler that is running when none are available to
perform DHW heating. When this happens, the boiler will not shut
down, but keep running during the change from space heating to
DHW (Hot Swap). Once the DHW cycle completes, the boiler will
shut down and wait to be called for space heating again.
