12.3.1 Function test without buffer cylinder
Note
If the appliance is operated solely through the WPM heat
pump manager, and an external pump that is not con-
trolled by the WPM is used as a heating circuit pump, you
will have to adjust the heating circuit pump manually.
For systems without a buffer cylinder, one or more heating cir-
cuits in the system must remain open. The open heating circuit(s)
must be installed in the lead room (room in which the external
programming unit is installed, e.g. living room or bathroom). The
lead room can be individually controlled using the external pro-
gramming unit, or indirectly by adjusting the heating curve or
activating room influence.
f Operate the appliance in heating mode.
f When designing underfloor heating in the lead room, ob-
serve our recommendations. The table applies if individual
room control is installed.

12.3.3 Systems without a buffer cylinder
In systems without a buffer cylinder, the minimum flow rate of the
heat pump must be ensured via permanently open heating circuits
for the underfloor heating system.
The design of the underfloor heating system determines the pos-
sible flow rate through the permanently open heating circuits.
If the flow rate of the permanently open heating circuits is less
than the minimum flow rate of the heat pump, check whether the
available external delivery head of the heating circulation pump
is sufficient.
