7.5. Terra CL-BA heat pump with Hygienik and without separation plate and
heating buf fer
For larger systems (over approx. 27kW), with either signifi cant hot water consumption or a very low hot water
consumption, it is advisable to separate the heating buffer and the Hygienik. The buffer in question is heated
via the priority valve as required. For hot water supply, a Hygienik without separation plate is used.
When using a fl ow meter to measure the heat volume, the sensor B39 must be fi tted in an immer-
sion sleeve in the heat pump return directly in the heat pump (see installation instructions fl ow
meter).
