"cooling" (accessory required) means operating mode
cooling for the heating medium pump.
If there are accessories for cooling present or if the heat
pump has a built-in function for cooling you can also set
the heating medium pump speed during active respect-
ively cooling operating modes (the heating medium
pump then runs in manual operation).

NIBE F1145
Menu 5.1.22 - heat pump testing
NOTE
This menu is intended for testing F1145 accord-
ing to different standards.
Use of this menu for other reasons may result
in your installation not functioning as intended.
This menu contains several sub-menus, one for each
standard.
Menu 5.2 - system settings
Make different system settings for the heat pump here,
e.g. master/slave settings, docking settings and which
accessories are installed.
Menu 5.2.1 - master/slave mode
Setting range: master, slave 1-8
Default value: master
Set the heat pump as master- or slave unit. In systems
with one heat pump it must be "master".
Caution
In systems with several heat pumps each pump
must have a unique name, that is only one heat
pump can be "master" and only one for example
can be "slave 5".
Menu 5.2.2 - installed slaves
Set which slaves are connected to the master heat pump.
There are two ways of activating connected slaves. You
can either mark the alternative in the list or use the
automatic function "search installed slaves".
search installed slaves
Mark "search installed slaves" and press the OK button
to automatically find connected slaves for the master
heat pump.
NOTE
Before these settings are made, each slave must
have received a unique name (see menu 5.2.1).
Menu 5.2.3 - docking
Enter how your system is docked regarding pipes, for
example to pool heating, hot water heating and building
heating. The menu is only displayed if at least one slave
is connected to the master.
TIP
Examples of docking alternatives can be found
at www.nibe.eu.
This menu has a docking memory which means that the
control system remembers how a particular reversing
valve is docked and automatically enters the correct
docking the next time you use the same reversing valve.
