start delta-T, stop delta-T: Here, you can set the temper-
ature difference between solar panel and solar tank at
which the circulation pump will start and stop.
max. tank temperature, max. solar collector temp.: Here,
you can set the maximum temperatures in the tank and
solar panel respectively at which the circulation pump
will stop. This is to protect against excess temperatures
in the solar tank.
If the unit has an anti-freeze function, solar panel cooling
and/or passive/active recharging you can activate them
here. When the function has been activated, you can
make settings for them. "solar panel cooling", "passive
recharging" and "active recharging" cannot be combined,
only one function can be activated.
freeze protection
anti-freeze temperature: Here, you can set the temper-
ature in the solar panel at which the circulation pump is
to start to prevent freezing.
solar panel cooling
start solar collector cooling: If the temperature in the
solar panel is higher than this setting, at the same time
as the temperature in the solar tank is higher than the
set maximum temperature, the external function for
cooling is activated.
passive recharging
activation temperature: If the temperature in the solar
panel is higher than this setting, the function is activated.
However, the function is blocked for an hour if the
temperature of the brine entering the heat pump (BT10)
is higher than the set value for "max brine in" in menu
5.1.7.
deactivation temperature: If the temperature in the solar
panel is lower than this setting, the function is deactiv-
ated.
active recharging
activating dT: If the difference between the temperature
in the solar panel (BT53) and the temperature of the
brine entering the heat pump (BT10) is greater than this
setting, the function is activated. However, the function
is blocked for an hour if the temperature of the brine
entering the heat pump (BT10) is higher than the set
value for "max brine in" in menu 5.1.7.
deactivating dT: If the difference between the temper-
ature in the solar panel (BT53) and the temperature of
the brine entering the heat pump (BT10) is lower than
this setting, the function is deactivated.

Setting range: on/off
Factory setting: off
Make settings for step controlled addition here. Step
controlled addition is for example an external electric
boiler.
It is possible, for example, to select when the additional
heat is to start, to set the maximum number of permit-
ted steps and whether binary stepping is to be used.
When binary stepping is deactivated (off), the settings
refer to linear stepping.
