Settings for other systems or devices

If other specific systems or devices are installed in the system, additional
menu items will be available. Depending on which system or device is
being used and the associated assemblies or components, various
settings can be made. Observe the additional information on the settings
and functions in the technical documentation for the relevant system or
device.
Settings for a swimming pool
Menu: Pool
Menu item Description
Switch on pool This setting enables the pool heating when it is
heating activated.
Pool The water in the pool is heated to this temperature.
temperature
Allow add. heater This setting allows the auxiliary heater to supply
for pool heating for the pool if the heat pump cannot reach
the set temperature.

Settings for smart grid
This menu is only available if a smart grid system is installed.
Menu item Control range: Function description
Heating The energy available in the smart grid is used for heating, if
the system is in heating mode.
[Selectable increase]: 0...5 °C
Set how much the room temperature may be increased.
[Forced increase]: 2...5 °C
Set how much the room temperature is forced to increase.
DHW The energy available in the smart grid is used for DHW.
[Selectable increase]: [Yes] | [No]
If enabled the DHW is heated to the temperature set for
DHW operating mode [Always on - DHW comfort].
No heating is done if the holiday program is active.

Settings for a hybrid system
This menu is only available if a hybrid system is installed. The system
then has two heat sources; a heat pump and a separate conventional gas
or oil burner.
Depending on the current situation and heat requirements, either the
heat pump or the conventional heat source offers a more favourable
energy/price ratio. Based on this ratio the controller decides which heat
source to operate.
The energy/price ratio must be adjusted regularly to the actual price
ratios.
The ratio is calculated with these formulas:
• Ratio for gas = (cost of electricity per kWh / cost of gas per kWh) X
heat factor of boiler
• Ratio for oil= (cost of electricity per kWh / cost of oil per liter) X heat
factor of boiler
Example:
• Cost of electricity = 24 ct/kWh
• Cost of gas = 8 ct/kWh
• Heat factor of boiler = 0,902
• Energy/price ratio = (24/8)X 0,902 = 2,7
The heat factor of the boiler (boiler efficiency) must be adapted to the
installed appliance ( manual of the appliance).

Setting a time program for an auxiliary heater
This menu is only available if an auxiliary heater is installed in the heating
system.
Menu: time prog. for add. heater
Menu item Description
Start add. heater With this setting activated the auxiliary heater will
time pr. only be allowed to operate in the [on] phases.
My time program Set the time program for the auxiliary heater.
Reset time prog. Reset the time program to the default settings.
Time prog min Below this outdoor temperature the time program is
outd temp off and the auxiliary heater can operate at any time.
[off] means that the time program runs regardless of
the outdoor temperature.

Settings for a photovoltaic system
Make the photovoltaic (PV) specific settings in this menu. Select if the
available energy should be used for Heating or DHW.
If photovoltaic energy is available and a buffer cylinder is installed with all
heating circuits mixed, the buffer cylinder will be heated to the heat
pump maximum temperature.
Menu: PV system
Menu item Control range: Function description
Heating increase The energy available in the PV system is used for heating, if
the system is in heating mode.
Set how much the room temperature may be increased
0...5 °C.
DHW increase The energy available in the PV system is used for DHW.
Yes | No
If enabled the DHW is heated to the temperature set for
DHW operating mode. No heating is done if the holiday
program is active.
Cooling setback The energy available in the PV system is used for cooling.
mode Yes | No
If enabled the room temperature is decreased to the
temperature set for cooling operating mode. No cooling is
done if the holiday program is active.
Only cool with PV Cooling mode is activated only if energy is available in the
PV system.
Yes | No
If enabled the room temperature is decreased to the
temperature set for cooling operating mode. No cooling is
done if the holiday program is active.
