    Start function Start function Simple description of the function: Sometimes, the collector sensor is not immersed in the heated heat medium quickly enough. In other words, the system goes into operation too late. There may not always be enough gravity force if the collector fields are completely horizontal, if the connections between the absorber strips meander, and especially if vacuum tubes are used with forced circulation.

  • Page 59 Heating circuit controller HEAT CURVE The flow temperature is usually calculated from the outdoor temperature and the heating curve. The heating curve is calculated based on a room set temperature of +20°C and is subject to an appropri- ate parallel offset for other room set temperatures. An exception is the fixed value control. The flow is set in setback mode to the listed temperature of +10°C and in standard mode to that of -20°C.

  • Page 77: Pid Control (Speed Control)

    PID control PID control (speed control) The PID control can be used to change the delivered quantity – i.e. the volume flow – of usual com- mercial circulating pumps. That allows the system to maintain temperatures (differences). It can be used not only for the speed control but also for the control of the burner performance and others.
  • Page 78 PID control Waveform Two waveforms are available for motor control (in the menu “Outputs”). Wave packet - only for circulating pumps with standard motor dimensions. Here, individual half- waves are blended in to the pump motor. The pump is run via pulses; the “smooth running” of the motor is only due to the moment of inertia.
  • Page 79 PID control Pump standstill The wave packet method (standard) allows the volume flow to be changed by a factor of 10 in 30 increments. If the flow rate is too low, return flaps may cause a standstill as well as a low output of the pump at low speeds of the control unit.
  • Page 80 PID control  Event control “overwrites” the results of speed control from other control processes. Hence, a set event can block the absolute value control or differential control. Example: Keeping the collector temperature at 60°C with the absolute value control is blocked when the cylinder has already reached 50°C at the top = the fast provision of DHW is complete and is now to be con- tinued with full volume flow (and hence a lower temperature but slightly better efficiency).

Besides the heating circuit and charging pump module this module represents an extremely versatile and important link to the burner demand.
  • Page 82 Analogue function Example of use: The greatest temperature that the system currently demands is calculated from the three functions "heating circuit 1." "heating circuit 2" (output variable = set flow temperature), and DHW demand (output variable = effective set temperature) so that the burner demand is later correctly compared to the buffer cylinder temperature.

  • Page 90 Timer function Run-on time: The ON signal at the trigger input immediately switches the output on. If the input drops (OFF), the output remains ON for the duration of the timer period. Delay: The ON signal at the trigger input is only passed on when the timer period at the output has elapsed.
  • Page 91 Timer function Astable: By indicating a switch-on and off time, a pulse generator is created without a trigger input. If the pulse-duty factor is also used for controls, it changes the switch-on time. The setting switch-off time = 0 is a special case: The switch-on time then corresponds to the entire period, and the pulse- duty factor to the relationship between the switch-on and the switch-off time Example: A duty factor of 30% results in 30% ON and 70% OFF for the entered switch-on time.
