You can set shunt valve amplification and shunt valve
waiting time.
Selecting "prioritised additional heat" uses the heat from
the external additional heat instead of the heat pump.
The shunt valve is regulated as long as heat is available,
otherwise the shunt valve is closed.
TIP
See the accessory installation instructions for
function description.

MENU 5.1.22 - HEAT PUMP TESTING
NOTE
This menu is intended for testing F1355 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 5.1.24 - BLOCKFREQ
blockFreq 1
Selectable setting range in the display:
start: 17 – 115 Hz
stop: 22 – 120 Hz
Maximum setting range: 50 Hz.
blockFreq 2
Selectable setting range in the display:
start: 17 – 115 Hz
stop: 22 – 120 Hz
Maximum setting range: 50 Hz.
Here you can set a frequency range where the com-
pressor is blocked. The parameters for the setting range
differ depending on which product is controlled by the
setting.
NOTE
A large blocked frequency range can cause the
compressor to run jerkily.
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".
This menu is also set in the slave heat pump's limited
menu system.
Caution
In systems with several heat pumps, each
pump is allocated a unique ID. In other words,
only one heat pump can be "master" and only
one 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".
