Secondary adjustment
Air is initially released from the hot water and venting may
be necessary. If gurgling sounds can be heard from HBS
16 or from the climate system, the entire system will re-
quire additional venting.
NOTE
Use bleed valve (QM20), any external bleed valves as
well as safety valve (FL2). The latter must be operated
carefully as it opens quickly. When the system is stable
(correct pressure and all air eliminated) the automatic
heating control system can be set as required.
See Default setting on page 8.
