Note:
The attainable hot water
temperatures depend heavily on
the design of the combo tank.
With a combo tank without
separating plate the additional
buffer tank (3) ensures
defrosting when air-to-water
heat pumps are implemented.
A sensor in the lower part of the
combo tank blocks the heat
pump and activates the mixer
regulation. The water in the
combo tank is heated by solar
energy and is also used for
supplementary heating (see
also Chap. 8.9.3 on p. 185).

Order of priorities:
Hot water preparation has
priority over heating and
swimming pool preparation (see
Chap. 8.10 on p. 185)
A relay module (special
accessory) is required for the
control of the M19 swimming
pool circulating pump.
