7.3.15.4 Standby Setup

When water reaches desired temperature, the heating switches off and
enters standby mode until water temperature doesn't drop for the standby
level difference.

Factory setting for standby difference 7 °C.
Setting area: AUTO or 2 °C – 10 °C.
Setting step: 0,1 °C..

Example: Water heating will deactivate after reaching the desired
temperature 55 °C. Heating will reactivate once temperature drops for the
standby difference

7 °C, thus to 48 °C.

Dynamic standby

:

In case of setting the standby temperature to AUTO, the standby temperature changes in
regards to the set desired water temperature. If the temperature set is 40 °C, standby
temperature

difference is 5 °C, while in the case of water temperature 55 °C and more,

standby equ

als 10°C. Between temperatures 40 °C and 55 °C the standby temperature

difference is calculated in a linear way between 5 and 10 °C.

Static standby

:

Other standby settings are static and are the same for all water temperatures. The minimal
temperature difference is thus 2 °C, and the maximal 10 °C. Factory standby difference is set
to 7 °C.

7.3.15.5 Temperature Settings for PHOTOVOLTAICS Programme

Device in the programme PHOTOVOLTAICS - PV (solar photovoltaic
system) (chapter 8.3.4) heats sanitary water to PV temperature setting.

The factor

y setting is 70 °C.

Setting range: 55 °C – 75 °C.
Setting step: 0,5 °C..

7.3.15.6 Standby in PHOTOVOLTAICS Programme

When the temperature of sanitary water in the programme PV (chapter 8.3.4)
drops under the set desired temperature for the programme PV for the
temperature deviation value (»Standby in PHOTOVOLTAICS Programme«),
the device resumes heating the sanitary water.

Factory temperature deviation setting is 3 °C
Setting range: 1 °C – 20 °C.
Setting step: 0,1 °C
