303.2.2 Reloading the system diagramThe system diagram can be reloaded at any time, e.g. if the automatic configurationwas incomplete due to a power failure or if you want to select a different systemdiagram. The following steps must then be performed:1. Press and hold “OK” until the controller asks for an access code. Using “+”,“-“ and “OK”, enter the access code “4444”.2. Press “OK” and the controller will switch to the “MCR/BMS” menu.Pressing “UP” will navigate to the main menu.3. Using “DOWN”, select the “System diagram“ menu item. Press “OK” toenter the “System diagram” menu.4. Change the parameter sysDiagram to your selected system diagram numberby using “+”, “-“ and “OK”.5. Press “DOWN“ to select the parameter type sensor. Changing the defaultsetting (“0”) is only necessary if a foreign sensor (1=Ni1000, 2=NI1000LG)will be used. Choose the desired sensor type for the system by using “+”, “-“and “OK”.6. When selecting a system diagram which includes communication with theheat pump(s) (4xxxx; 5xxxx, 6xxxx, 7xxxx), the type(s) of heat pumps mustbe entered in the parameters type-HP1, type-HP2 and type-HP3. Here, theidentification “-1” (according to the type label on the heat pump) must beentered (e.g. “SXC12D90E8-1”). “+”, “-“ and “OK” enables adjusting eachcharacter in the line.7. If the type entered is not accepted when pressing “OK”, then communicationwith a heat pump of this type is not possible. An overview of all compatibleheat pumps is contained in the appendix.8. Use “DOWN” to select the parameter cold start. Change the parameterto”1” by using “+”. Press “OK”.9. When the display shows “SYSTEM XXXXX LOADED”, the process iscomplete. The controller is now ready for operation.CAUTION!When performing a cold start, all previously performedadjustments are lost and all parameters are reset to theirdefault values!3.2.3 Manual configuration (loading of diagram “99999”)If the HPM tool is not offering a system diagram number that fits the current system,the system diagram “99999” can be selected and the entire controller then configuredmanually.After setting the type of heat pump to “1= release via contact” or to the actual producttype (e.g. “SXC12D90E8-1”) or to “” ” (no type) = HP not existing“, the selection forthe other control circuits (buffer tank, DHW circuit and heating circuits) should alsobe set to a value (0,1,2). When performing a cold start, the controller will be freshlyinitialized.After the cold start, all input and output terminals of the control circuits must beassigned according to the system specifications.
