[6] Option setup
■
[6-00] Domestic hot water tank option
If the domestic hot water tank is installed, its operation must be
enabled by field setting. Default [6-00]=0 which means no tank is
installed. Set [6-00] to 1 if the optional domestic hot water tank is
installed.
INFORMATION
When enabling the domestic hot water tank option be
aware that the advised default settings become active:
■
[1-00]=1=automatic night storage
■
[4-00]=1=disinfection function
■
[6-01] External room thermostat option
If the optional external room thermostat is installed, its operation
must be enabled by field setting. Default [6-01]=0, which means
no external room thermostat is installed. Set [6-01] to 1 if the
optional external room thermostat is installed.
The external room thermostat only gives an ON/OFF signal to
the heat pump based on the room temperature. Because it does
not give continuous feedback information to the heat pump, it is
supplementary to the remote controller room thermostat
function. To have a good control of the system and avoiding
frequent ON/OFF it is advised to use the automatic weather
dependent set point operation.

■
[8-00] Remote controller temperature control
When using the remote control delivered with the unit, 2 types of
temperature control are possible. Default [8-00]=1 which means

temperature control.

[8-03] Quiet mode
The unit has a quiet mode functionality for which 3 levels can be
selected:
■ [8-03]=1 low noise level 1 (default)
■ [8-03]=2 low noise level 2
■ [8-03]=3 low noise level 3
Activating this quiet mode is done by pushing the QUIET MODE
button on the remote controller or through the schedule timer.
■
[8-04] Freeze-up prevention
The unit has a freeze-up prevention functionality for which
3 levels can be selected:
■ [8-04]=0 prevention level 0 (default: no prevention)
■ [8-04]=1 prevention level 1
■ [8-04]=2 prevention level 2
The freeze-up prevention is only active when the unit is in
thermo OFF condition. If prevention level 1 is enabled, the
freeze-up prevention will start if the outdoor ambient
temperature <4°C and if leaving or return water temperature
<7°C. For prevention level 2, the freeze-up prevention will start
as soon as the ambient temperature <4°C.
For both cases the pump will operate and if leaving or return
water <5°C for 5 minutes the unit will start up to prevent too low
temperatures.
It is advised to enable freeze-up prevention if the indoor unit is
located in a colder ambient room (e.g. garage, ...) to prevent
for
water freeze-up.
