Secondary adjustment
Air is initially released from the hot water and venting may be
necessary. If bubbling sounds can be heard from the heat pump,
the circulation pump and radiators the entire system will
require further venting. When the system is stable (correct
pressure and all air eliminated) the automatic heating control
system can be set as required
