Page 11: Statistics
2. Statistics Serve for function control and long-term monitoring of the system. For time-dependent functions such as circulation and anti-legionella and the evaluation of system data, it is essential that the time is accur- ately set on the controller. Please note that the clock continues to run for about 24 hours if the mains voltage is interrupted, and afterward must be reset. -
Page 12: Operating Mode
3. Operating mode Auto The automatic mode is the normal mode of the controller. A correct controller function under consideration of the current temperatures and the set parameters is only present in automatic mode! After an interruption of the mains voltage, the controller automatically returns to the last operating mode selected. -
Page 13: Settings
4. Settings By no means does the controller replace the safety appliances on site! Minimum storage temperature If this value falls below this value at the associated storage sensor outside the enable times for heating, the heating is nevertheless star- ted. -
Page 14: Seizing Protection
In the delivery state, the anti legionella function is switched off. As soon as it has heated up with “AL” turned on, information with the date will be shown in the display. This anti legionella function does not offer any secure protection against legionella, because the controller requires an adequate added amount of energy and the temperatures cannot be monitored in the entire storage area and the connected pipe system. -

Type of pump/ Type of signal The type of speed controlled pump used can be set here. 0-10V: Control of special pumps (e.g. high efficiency pumps) through a 0-10V signal. PWM: Control of special pumps (e.g. high efficiency pumps) through a PWM signal. Pump/ Profile In this menu, the preset profiles for the pump can be selected or under “manual”... -
Page 16: Circulation
The sequence in this list does not correspond to the menu numbering in the controller. Circulation Depending on the temperature and time approval, a circulation pump is turned on for the DHW storage. Circulation Activate function. Tmin If this value at the circulation sensor is undershot and the circulation is approved or there is a request through a tapping process, the circulation pump is started. -
Page 17: Primary Mixer
Primary Mixer When this function is activated, water is mixed in the primary circuit by a mixer via the primary return. As a result, less energy is drawn from the storage tank at high storage tank temperatures, depending on the flow rate, since energy is mixed from the return flow. Primary flow temp. -
Page 18: Pressure Monitor
Please pay attention to the technical information for the PWM/0-10V outputs. Pressure monitor In this menu, the system pressure monitoring can be activated through a direct sensor. As soon as the set pressure conditions are undershot or exceeded, the set relay will switch on. Pressure monitor Relay turns on if the pressure goes below the minimum or exceeds the maximum. -

7. Menu Lock Secure the controller against unintentional changing and compromise of basic functions. Menu lock active = "On" Menu lock off = "Off" In addition, the "Simple" menu view can be used to hide menu items that are not necessary for the daily use of the controller after commissioning. -
Page 21: Malfunctions/Maintenance
Malfunctions/Maintenance Replacing the Fuse Repairs and maintenance may only be performed by a specialist. Before working on the unit, switch off the power supply and secure it against being switched on again! Check that there is no power flowing! Only use the included safeguard or a similar safeguard with the following specifications: T2A / 250 V. - Page 22 Tips The service values include not only current measurement values and operating states, but also all of the settings for the con- troller. Write the service values down just once after commissioning has been successfully completed. In the event of uncertainty as to the control response or malfunctions the service values are a proven and successful method for remote diagnosis.
