[3-00] Low ambient temperature
temperature.
[3-01] High ambient temperature
temperature.
[3-02] Set point at low ambient temperature (Lo_Ti): the target
outgoing water temperature when the outdoor temperature
equals or drops below the low ambient temperature (Lo_A).
Note that the Lo_Ti value should be higher than Hi_Ti, as for
colder outdoor temperatures (i.e. Lo_A) warmer water is required.
[3-03] Set point at high ambient temperature (Hi_Ti): the target
outgoing water temperature when the outdoor temperature
equals or rises above the high ambient temperature (Hi_A).
Note that the Hi_Ti value should be lower than Lo_Ti, as for
warmer outdoor temperatures (i.e. Hi_A) less warm water suffices.
NOTE If by mistake the value of [3-03] is set higher than the
value of [3-02], the value of [3-03] will always be used.
[4] Disinfection function
This mode will disinfect the domestic hot water tank by periodically
heating the domestic water to a specific temperature.
NOTE If a domestic hot water tank is installed, the disinfection
function is enabled by default.
[4-00] Status: defines whether the disinfection function is turned
ON (1) or OFF (0).
[4-01] Operation interval: day of the week at which the domestic
water should be heated.
[4-02] Start time: time at which the disinfection operation is
started
Even if all schedule timers are de-activated and there is no reheat
function active, the disinfection function will operate if a domestic hot
water tank is installed and field setting [4-00] is set to ON.
The disinfection function field settings must be configured
by the installer according to national and local regulations.
Refer to "[5] Automatic setback and disinfection set point" for
temperature set points.
[5] Automatic setback and disinfection set point
See also "[4] Disinfection function" on page 21 for more information
about the disinfection operation.
[5-00] Set point: disinfection water temperature to be reached
[5-01] Interval: time period defining how long the disinfection
temperature set point should be maintained

[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.
NOTE 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.
[6-04] Benefit kWh rate power supply mode
If benefit kWh rate power supply is used, the mode must be
selected. Default [6-04] = 0 which means no benefit kWh rate
power supply is used.
Set [6-04] to 1 to use benefit kWh rate power supply mode 1
(normally closed contact which will open when the power supply
is interrupted), or set [6-04] to 2 to use benefit kWh rate power
supply mode 2 (normally opened contact which will close when
the power supply is interrupted).
See "Connection to a benefit kWh rate power supply" on page 15 for
more information.
[7] Option setup
[7-00] Bottom plate heater option
An optional bottom plate heater can be installed in your outdoor
unit. In case an RRRQ* outdoor unit (special model with
freeze-up countermeasures) is installed, the unit will have the
bottom plate heater already standard installed.
If the bottom plate heater is installed, its operation must be
enabled by field setting. Default [7-00] = 0 which means no
bottom plate heater is installed. Set [7-00] to 1 if the bottom
plate heater is installed.
