3.2.1 To check the water volume and flow rate
Minimum water volume
Check that the total water volume in the installation is minimum
13.5 litre, the internal water volume of the indoor unit NOT included.
INFORMATION
In critical processes, or in rooms with a high heat load,
extra water might be required.
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.

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
Check that the minimum flow rate (required during defrost/backup
heater operation) in the installation is guaranteed in all conditions.
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,
a flow error 7H will be generated (no heating/operation).
See the installer reference guide for more information.
Minimum required flow rate
05 models 7 l/min
08 models 8 l/min
See the recommended procedure as described in "6.2 Checklist
during commissioning" on page 20 .
