Air is initially released from the hot water and venting
may be necessary. If bubbling sounds can be heard
from the heat pump, the entire system requires further
venting. NOTE! Safety valve (52) also acts as a man-
ual venting valve. Operate it with care, since 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 the section Room
temperature - Setting the Automatic heating control
system and Front panel.
The flow should be trimmed in hot water mode using
the trim valve (81).
The temperature difference can be read on menu 5.15
on VVM 240.
