    Operation Operation The controller is ready for use with the temperatures and operating schedules preset by the manufacturer. 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 7: Rotary Switches

    Operation 1.1.2 Rotary switches Use the three rotary switches to adjust the desired 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 130). The rotary switch in the middle is not used in systems without a second heating circuit.

    Operational faults Operational faults Malfunctions or faults are indicated by the blinking icon on the display. The “Error“ alarm is displayed immediately. Press the rotary pushbutton to open the error level. It may be possi- ble to view several error alarms by turning the rotary pushbutton. As long as an error alarm is present, the error level is displayed, even though it has not been opened by pressing the rotary pushbutton.

    Operational faults Flow sensor(s) in heating circuit(s): When the flow sensors in the heating circuits are de- fective, the associated valve moves to 30 % travel. DHW heating using such a sensor to measure the charging temperature is suspended. Flow sensors in the DHW circuit with control valve: When the flow sensor VF4 fails, the controller behaves as if VF4 had not been configured.

If an error message is transmitted via the device bus to a controller equipped with a dial-up modem, the serial number of the faulty controller is transmitted, not that of the “modem controller“.

  • Page 92: Communication

    – Operation at a four-wire or two-wire bus To establish the link between controller and bus line, the signal level needs to be converted by an appropriate converter (four-wire bus: SAMSON cable converter 1400-7308, two-wire bus: SAMSON cable converter 1400-8800).

  • Page 93: System Bus Interface

    Communication Note! Regardless of whether communication is established via modem or data cable, the operating software can be updated using the serial system bus interface, provided Modbus has been activated (CO6 -> F01 - 1). RS-232 system bus interface When looking onto the controller front, the system bus connection is located on the left side inside the controller housing (RJ-45 jack).

  • Page 95: Description Of Communication Parameters To Be Adjusted

    Communication If you wish to use more than 126 devices in line or need to bridge greater distances, make sure repeaters (e.g. TROVIS 5482) are installed to replicate the signal. With 8-bit address- ing, a maximum of 246 devices can be addressed and connected to a bus. If there is no communication between the control system and the controller, interventions of the control system in dynamic processes can be limited with regard to time using the Control system monitoring function.
  • Page 96 Communication Cyclical initialization (I) This parameter defines the period of time for a cyclical issue of the initialization command “ATZ“. The command is not issued during dial-up or when connected. “ATZ“ causes the pro- file 0 to be copied to the active profile, provided the modem parameters have been set and saved in profile 0 using a suitable terminal program.

  • Page 97: Meter Bus Interface

    Communication Meter bus interface With the help of an optional, retrofittable meter bus plug-in module, the TROVIS 5576 Heating and District Heating Controller can communicate with up to 3 heat or water meters according to EN 1434-3. A flow rate or capacity limitation is possible on the basis of the values measured at heat meter WMZ1.

  • Page 98: Flow Rate/Capacity Limitation Using Meter Bus

    Communication Note! With reading mode “24h“, the displayed values are not updated by reopening the levels “buS 1“ to “buS 3“; the values read during the last cycle remain unchanged. With reading mode “CONT“, the values in the levels are not continuously updated. You have to reopen the specific level to get current values.
  • Page 99 Communication In all systems without DHW heating or without heating circuit, only the Max. limit value for the flow rate or capacity can be specified. In systems Anl 11.x, the heating circuit is turned down in case of limitation. Note! This function is not available in systems Anl 10.x.
