9.6 WPM 3 heat pump manager
A WPM3 heat pump manager is required to operate the appliance.
This controls the entire heating system.
9.7 Buffer cylinder
A buffer cylinder is recommended to ensure trouble-free appliance
operation.
The buffer cylinder provides hydraulic separation of the volume
flows in the heat pump circuit and heating circuit, and also serves
as an energy source for defrosting.
When operating without buffer cylinder, observe the details
specified in chapter "Minimum flow rate with individual room
controller by means of FEK / FE7 in the case of systems with-
out buffer cylinder".

Material losses
A buffer cylinder with diffusion-proof insulation is essen-
tial for cooling mode.
