NOTICE
When circulation in each space heating loop is controlled by remotely controlled
valves, it is important that the minimum water volume is guaranteed, even if all of
the valves are closed.

Minimum flow rate
A minimum flow rate must be guaranteed so that the outdoor unit does not go in
high pressure error (A5). For guidelines on flow rates, see the tables in
"8.3.1Water piping lengths and height difference "[459].
NOTICE
When circulation in each or certain space heating loops is controlled by remotely
controlled valves, it is important that the minimum flow rate is guaranteed, even if all
valves are closed. In case the minimum flow rate cannot be reached, the heat pump
generates a high pressure error (A5).
Minimum required flow rate

(a)
(a) Below this value, no stable operation can be guaranteed.
8.3.5 Changing the pre-pressure of the expansion vessel
NOTICE
Only a licensed installer may adjust the pre-pressure of the expansion vessel.
The expansion vessel is available with the B-pack (see "Possible options for the gas
boiler"[432]) or as a third-party vessel. For more information on how to change
the pre-pressure, see the manual of the expansion vessel.
Changing the pre-pressure of the expansion vessel should be done by releasing or
increasing nitrogen pressure through the Schrader valve of the expansion vessel.
