Hyko Hygiene Combination Tank; Fresh Water Module - SOLARFOCUS ecotopzero Manual

7 DHW heating
Example
- Required temperature 1 = 55°C
- Hysteresis = 10°C
The DHW tank charge starts when the DHW tem-
perature falls to 45°C (requirement: The temperature
of the energy source is 5°C above 45°C).
If the DHW tank temperature falls below the value
minimum temperature outside the release time, the
DHW tank is charged.
Within the release time the DHW tank is charged to
the desired temperature as required.
One-time charge
This button is pressed to perform one-off re-heating
of the DHW tank (e.g. if no release times are defined
or the operating mode Always Off is set).
DHW tank operating mode
Always off: The DHW tank charge pump is switched
off permanently.
Exception for frost protection mode: The DHW tank
charging pump is activated if
- the outside temperature is <2°C, and
- the DHW tank temperature falls to <10°C.
Always on: The DHW tank charge pump is switched
on permanently. The pump is controlled taking the
parameters required temperature 1, minimum tem-
perature and hysteresis into account.
Time switching (Monday-Sunday, by block, by day,
etc.): Various time ranges can be set in which the
DHW tank charging pump is switched to on.

The operating mode Monday - Sunday is not
available when using the mySOLARFOCUS

7.2 HYKO hygiene combination tank

This tank is used for processing hot water and heat-
ing water at the same time. The hot water is fed into
the hot water via a stainless steel corrugated pipe coil
in circulation operation and heated up hygienically in
this way. In addition, up to two solar coils can be
installed in the HYKO combi tank depending on the
model.

7.3 Fresh water module

A fresh water module heats hot water in circulation
operation via an external heat exchanger. The cir-
culation pump of the fresh water module starts when
a DHW output point is opened. The energy for heat-
ing up hot water is taken from the upper area (=DHW
area) of the buffer tank.
