Panasonic PAW-HPM 1 User Manual

35To reach the menu for making these adjustments starting from the default display,press “OK” and select “domestic hot water (DHW)” using “DOWN”. Enter themenu using “OK” and then select “setpoints” and press “OK”. This menu contains allparameters required for the occupation (SP-OTx) and non-occupation times.3.3.5 Heating Circuits – Setpoints, heating curve, setpointlimitationAfter loading the system diagram, the HPM will automatically configure theparameters in the heating circuit for weather-dependent flow temperature calculationfor underfloor heating systems. Therefore, a flat heating curve has been chosen(Slope: hCu-slope = 0.5), along with a small exponent (radiator exponent: hCu-exp= 1.10) and a comfortable base point (basepOTx = 22°C). These parameters can befound in the menu “heating circuits / heating circuit x / setpoints”.To reach the menu in order to make adjustments, press “OK” (starting from thedefault display) select “heating circuits” with “DOWN” and enter the menu using“OK”. In the next menu, the heating circuit will likely have to be selected. Select“setpoints” with “DOWN” and enter the menu using ”OK”. This menu contains allparameters needed for the heating curve.For alternative heating systems, the following adjustments must be made:Heating system Heating curve slope Radiatorexponentunderfloor heating (up to 35°C)0.2 (flow 29°C for outd.temp -10°C)0.3 (flow 32°C for outd.temp -10°C)0.4 (flow 35°C for outd.temp -10°C)1.10low temperature radiators (up to 45°C)0.5 (flow 38°C for outd.temp -10°C)0.6 (flow 41°C for outd.temp -10°C)0.7 (flow 44°C for outd.temp -10°C)1.20radiators and plate radiators(up to 55°C)0.8 (flow 48°C for outd.temp -10°C)0.9 (flow 51°C for outd.temp -10°C)1.0 (flow 55°C for outd.temp -10°C)1.20 – 1.40DIN: 1.33convectors (up to 65°C)1.1 (flow 58°C for outd.temp -10°C)1.2 (flow 61°C for outd.temp -10°C)1.3 (flow 65°C for outd.temp -10°C)1.40 – 1.66Table 3.3: Overview heating systems / heating curveWhen selecting a heating curve >0.5, the function “summer shutdown” will beautomatically set to type=2 (3-day caretaker). This means that the outdoortemperature has to be above the set threshold for 3 days in a row before the heatinggoes into “summer shutdown” mode. The same applies if the outdoor temperaturefalls below the switch-on threshold. The parameter “type” can be manually set to“1=comfort caretaker”, in the menu “heating circuits / heating circuit x / functions /summer shutdown”, if it is desirable that the summer shut-down should reactimmediately.A graph of the most commonly used heating circuits is contained in the appendix ofthis manual.Depending on the design of the heating system and the materials used in it, it mightbe necessary to set a setpoint limitation. This function ensures the flow temperaturewill not exceed a set maximum temperature (limitation), regardless of the selectedheat curve. The parameters for this function can be activated and set in the menu“heating circuits, heating circuit x / functions / setpoint limitation”. Theparameters “maxFl” and “maxDemFl-T” affect the setpoint limitation (maximumcalculated flow temperature) and the demand limitation (maximum demanded flowtemperature).
