Page 9: Operation
Operation Operation The controller is ready for use with the default temperatures and operating schedules. On start-up, the current time and date need to be set at the controller (–> section 1.5). Operating elements The operating controls are located in the front panel of the controller and protected by a Plexiglas door.
Page 10: Rotary Switches
Operation 1.1.2 Rotary switches Use the three rotary switches to adjust the required operating mode (icons on the left) and the relevant parameters (icons on the right). The top and middle switches are assigned to the heating circuits (see page 169). The rotary switch in the middle is not used in systems without a second heating circuit.

Functions of the heating circuit Functions of the heating circuit Which controller functions are available depends on the selected system code number (Anl).

The heating characteristic in the controller defines the flow tempera- ture set point as a function of the outdoor temperature (–>...
Page 75: Gradient Characteristic
Functions of the heating circuit Receive value AF2 CO7 -> F09 - 1; register no. 5.1.1 Gradient characteristic Basically, the following rule applies: a decrease in the outdoor temperature causes the flow temperature to increase. By varying the parameters Gradient and Level, you can adapt the characteristic to your indi- vidual requirements: The gradient needs to be increased if the room temperature [°C]...
Page 76 Functions of the heating circuit The level needs to be decreased and the gradient increased [°C] if the room temperature rises when it is mild outside. –20 [°C] Outside the times-of-use, reduced set points are used for control: The reduced flow set point is calculated as the difference between the adjusted values for Day set point (rated room temperature) and Night set point (reduced room temperature).
Page 77: Four-Point Characteristic
Functions of the heating circuit 5.1.2 Four-point characteristic The four-point characteristic allows you to define your own heating characteristic. It is defined by four points each for the Outdoor temperature, the Flow temperature, the Re- duced flow temperature and the Return flow temperature. The Max. flow temperature and Min. flow temperature parameters mark the upper and lower limits of the flow temperature.

Functions of the heating circuit Note: A fixed set point control in heating circuit 2 with CO2 -> F02 - 0 can only be config- ured if CO1 -> F02 - 0 is set as well, because the heating circuit 2 with CO2 -> F02 - 0 only uses the measured outdoor temperature provided by heating circuit 1.
Page 80: Deactivation Depending On Outdoor Temperature
Functions of the heating circuit The drying process has been successfully completed when the additional icon in the flow tem- perature display goes out after the last phase. Any power failure that occurs while the func- tion is running automatically restarts the drying function. In systems in which the drying function is interrupted due to DHW heating (e.g.
Page 81: Ot Activation Value In Rated Operation
Functions of the heating circuit ture falls below this value (less 0.5 °C hysteresis), heating operation is restarted immediately. With the default settings, this means that, at night, the system is switched off at an outdoor temperature of 15 °C to save energy. Nevertheless, remember that the system requires some time in the morning to heat up the building.
Page 82 Functions of the heating circuit storage tank is completed, the buffer tank can be charged. In system Anl 14.3, a solar circuit with reroutable heat transfer medium flow is integrated. If the temperature difference be- tween the collector sensor RüF2 and one of the tank storage sensors SF3 or SF4 is greater than the Solar circuit pump ON, the solar circuit pump UP2 is switched on and the corre- sponding storage tank is charged.
Page 83 Functions of the heating circuit Note: The buffer tank control circuit is deactivated as described in section x. When prede- fined gradients of heating characteristic (CO1 > F11 - 0) are used, night mode is not possi- ble in the buffer tank control circuit. In contrast to an active four-point characteristic (CO1 > F11 - 1): in this case, a four-point characteristic exists for day and night modes.

Page 85: Delayed Outdoor Temperature Adaptation
Functions of the heating circuit Delayed outdoor temperature adaptation The calculated outdoor temperature is used to determine the flow temperature set point. The heat response is delayed when the outdoor temperature either decreases, increases or in- creases and decreases. If the outdoor temperature varies by, for example, 12 °C within a very short period of time, the calculated outdoor temperature is adapted to the actual out- door temperature in small steps.

Functions of the heating circuit icons blink on the display. Outside the times-of-use, the controller monitors the Night set point (reduced room temperature).

Page 109: Three-Step Control
System-wide functions Three-step control The flow temperature can be controlled using a PI algorithm. The valve reacts to pulses that the controller sends when a system deviation occurs. The length of the first pulse, in particu- lar, depends on the extent of the system deviation and the selected Proportional gain K (the pulse length increases as K increases).

System-wide functions change performed by the proportional component (the greater T , the slower the rate of change). Due to the derivative component, any change of the system deviation is incorpo- rated into the output signal with a certain gain (the greater T , the stronger the change).

System-wide functions troller does not distinguish between a flow rate pulse signal or a capacity pulse signal. As the displayed current pulse rate P [pulse/h] (–> Extended operating level, key number 1999) is calculated depending on the interval between the received pulses, it is natural that the con- troller cannot react immediately to all rapid flow rate or capacity changes which occur in the system.
