NIBE F1155
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 is to start and stop.
max. tank temperature, max. solar collector temp.:
Here you can set the maximum temperatures in tank
respectively solar panel at which the circulation pump
is to 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 greater than this setting at the same time
that the temperature in the solar tank is greater than
the set maximum temperature, the external function for
cooling is activated.
passive recharging
activation temperature: If the temperature in the solar
panel is greater than this setting, the function activates.
The function is blocked for an hour if the temperature
of the brine in 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 less than this setting, the function deactiv-
ates.
active recharging
activating dT: If the difference between the temperature
in the solar panel (BT53) and the temperature of the
brine in the heat pump (BT10) is greater than this setting
the function is activated. The function is blocked for an
hour if the temperature of the brine in 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 in the heat pump (BT10) is less than this setting
the function deactivates.
