When using a fl ow meter to measure the heat volume, the sensor B39 must be fi tted in
an immersion sleeve in the heat pump return directly in the heat pump (see installation
instructions fl ow meter).
7.2. Terra CL-HGL heat pump with IDM Hygienik with separation plate
During the priority charging procedure, the top area of
the storage tank is charged with the speed-controlled
charging pump at the set HGL temperature.
During the heating operation of the heat pump,
a proportion of the fl ow is always charged into the
top storage tank area via the HGL exchanger and the
HGL valve at the set HGL temperature.
This keeps the Hygienik at the right temperature whilst
at the same time the lower storage tank area is better
used as a buffer due to the higher temperature, this
means
- longer running times for the heat pump
- longer deadtimes
- more tapwater and higher tapwater temperature
