34 Aries Installation and Commissioning manual
indicates the charging status of hot domestic water
Operating mode HMI
The operating mode is used to choose the functional status
of hot domestic water. In the
AUTO mode, the heat pump
prepares domestic water normally within the framework
of the set value and the connection difference. The heat
pump does not heat domestic water in
OFF mode.
AUTO / OFF
Set value Temperature
The set value of hot domestic water has an effect on the
sub sensor of the functional accumulator. Due to
accumulator layering, the actual temperature of domestic
water raises 5–10°C higher than the set value.
Factory setting 50˚C
You can change the domestic water set in the HOT DOM
WATER > SET VALUE TEMP menu.
COMFORT : The normal set value for domestic water.
This value changes, if you toggle the status of domestic
water COMFORT/NORMAL/ECO in the application
ECO : The domestic water temperature drop used in time
control
Legionella
The anti-bacterial function of hot domestic water. The
Legionella function raises the domestic water accumulator
temperature to the Legionella set value once a week. The
heat pump uses an electric heater for Legionella charging.
Set value temperature:
The set value to which the heat pump will charge the
accumulator temperature.
factory setting 55°C
Legionella function:
The weekday when the charging takes place.
Mon/Tue/Wed/Thu/Fri/Sat/Sun
Start time:
The time of day when the Legionella function starts
Legionella overcharge:
The time by which the Legionella charging exceeds the set
value.
Domestic hot water circulation pump
The domestic hot water circulation pump can be
controlled using the heat pump’s controller. The
circulation pump follows the schedule set for domestic hot
water. If domestic hot water is on, the circulation pump
will also be on.
12.3 HEATING
The heating system is circuit-specifically configured. The
heat pump regulator is capable of controlling two heating
circuits. Heating circuit 1 is always the heat pump’s
internal pump heating circuit for which a mixing function
cannot be configured. Heating Circuit 2 is an optional
mixing heating circuit that can be used to adjust a lower
temperature, for instance, to heat a garage. If you use two
heating circuits, circuit 1 should always have the higher
temperature.
Operating mode HMI
In the Operating Mode menu, you can turn a heating
circuit ON or OFF. The correct operating mode for
heating a property is the
AUTO mode.

OPERATING MODE HMI
Set point room temperature
The room temperature can be controlled according to the
room set point. The room temperature sensor must be
placed in a central part of the building in order for
regulation to function optimally.
The controller uses
COMFORT
-setting in normal heating
control and
ECO
-setting in time control reduced setting
period.
If the heating circuit does not include a room sensor, you
should disable the room sensor in the
Service Menu . In
this case, the regulator will use a 20-degree reference
value for heat control.
Control curve
The control curve is used to calculate the set point for
the supply water temperature, and this set point is
used to regulate the supply water temperature
according to the prevailing weather conditions.
The
control curve can be changed at five different external
temperature points so that the heating output and room
temperature can be adjusted as required.
A steeper control curve gradient means that the
temperature of the supply water changes more when the
outdoor temperature decreases. In other words, if the room
temperature is wrong when the outdoor temperature is low
but not when the outdoor temperature is high, the gradient
of the curve needs to be changed.
Increasing the setting: Increases the temperature
of the supply water, par-
ticularly at low outdoor
temperatures.
Decreasing the setting: Decreases the tempera-
ture of the supply water,
particularly at high out-
door temperatures.
The end user can make minor changes to the control curve
during the first heating period. See the
User manual for
instructions on this.
