The basic heating curve parameters (level/slope) are set during commissioning. The comfort
correction value is available for daily adjustments.
Yes, the function labels (e.g. ‘Heating circuit 1’) can be customised in the basic settings.
Yes, via the ‘WW Charge’ quick-select button in the hot water details view.
Via Settings → Time programmes.
- Up to 3 heating programmes per heating circuit
- Optional cooling programme
- Up to 6 switching times with different temperature settings are possible per day or block
You can switch between heating circuits and function modules (e.g. heating circuit, domestic hot water, buffer tank, solar) by tapping the arrow buttons < / > or by swiping on the touchscreen.
In the operating mode menu, select ‘Holiday settings’ and enter an end date. The heating circuit will run in reduced mode until then and will automatically switch back at midnight on the following day.
The hot water charging cycle starts automatically when the actual temperature falls 5 K below the setpoint and the timer programme gives the go-ahead.
Once the setpoint has been reached, the charging pump continues to run for 1–20 minutes.
If a circulation pump is installed, you can set your own switching times in the domestic hot water programme. This ensures that hot water is available more quickly at the taps.
The control system coordinates operation between the main and auxiliary boilers. In the event of sensor or functional faults, safety functions or default values are automatically activated.
Depending on the settings at the service level:
- Off
- Time control
- Temperature control (with sensor)
- Pulse control (push-button or flow switch)
Via WW charging: maximum charging priority at the service level. This setting determines how long the boiler charges hot water exclusively.
Yes, the hot water hygiene programme.
It is recommended that you heat the tank to at least 60°C once a week.
If higher temperatures are used, the maximum hot water temperature setting may need to be adjusted.
The control system calculates the flow temperature setpoint based on the outdoor temperature, the heating curve and, where applicable, the room temperature, and controls the pump, mixer and heat generator.
A timer-controlled function in which the solar pump is switched on and off at regular intervals to circulate stagnant fluid and initiate operation.
The start, end and duration are set in the operator level.
A function (e.g. cooling) was manually disabled during this period.
It shows, both graphically and as a percentage, how much energy is currently available in the buffer tank.
It temporarily adjusts the room temperature setpoint up or down without permanently altering the heating curve or time programmes.
All settings are saved. Any programmes currently running (e.g. the screed heating programme) will resume from where they left off once power is restored.
After a solid fuel boiler has finished burning, the automatic boiler is disabled for a set period of time (0 h = disabled) in order to utilise the residual energy in the buffer tank.
A protective function against corrosion. During the heating-up phase, the heating circuits and hot water supply are temporarily shut off until the boiler reaches operating temperature.
- Information level: Display of measured values and status information
- Operator level: Settings for daily operation (e.g. time programmes, operating modes)
- Start screen: Displayed when the boiler is switched on (if the control panel is built into the boiler).
- Main menu: Displays the current values for all available modules (boiler, heating circuits, hot water, solar, etc.). To switch to this screen, tap the start screen.
With Eco/Comfort, you can lower or raise the room temperature for a limited period (0–400 minutes). After that, the system automatically returns to the previous operating mode.

Information, error or alarm messages are shown on the display. Please refer to the code table in the user manual or contact a specialist service provider.
When the collector temperature falls below the minimum value or the storage tank has reached its maximum temperature.
If the collector temperature is at least 5 K above the buffer or hot water temperature and the maximum temperatures have not yet been reached.
In the detailed view for the auxiliary boiler and in the associated information layer (e.g. boiler temperature, setpoint).
You can find these settings under Settings → General Settings.
In the operator level → Time programme.
Up to 6 times per day or block with a setpoint temperature.
A setpoint of 0 °C disables buffer charging.
- Collector, buffer and hot water temperatures
- Pump speed
- Heat output
- Flow rate
- Operating mode (Off / Automatic)
The room temperature compensation setting may be too low. This value can be adjusted by qualified personnel in the service mode.
