Adjustment channelsThe heat quantity transported is measured by theindication of the volume flow and the reference sensorof feed flow S1 and return flow TRF. It is shownin kWh-parts in the indication channel kWh andin MWh-parts in the indication channel MWh. Thesum of both channels forms the total heat output.The heat quantity added up can be reset. As soon asone of the display channels of the heat quantity isselected, the symbol is permanently shown onthe display. The button (3) must pressed forapprox. 2 seconds in order to get into the RESETmodeof the counter. The display-symbol isflashing and the value for heat quantity will be setto 0, if the button is pressed within 5 seconds.In order to finish the RESET-operation, the button" " must be pressed in order to confirm within5 seconds once again.In order to cancel the RESET-operation, no buttonshould be pressed for about 5 seconds. The controllerreturns automatically into the indicaton mode.Please note: Channels kWh and MWh are onlyavailable during the activated option heat quantitymeasurement (OHQM).4.1.8 ∆T-regulationInitially the controller works in the same way asa standard differential controller. If the switch-ondifference (DTO/DT1O/DT2O/DT3O) is reached, thepump is activated and after having got an impulse(10 s) a minimum pump speed (nMN = 30%) is run.If the adjusted nominal value of the temperature difference(DT S/DT1S/DT2S/DT3S) is reached, thepump speed is increased by one step (10%).If the difference increases by 2 K (RIS/RIS1/RIS2/RIS3), the pump speed is increased by 10% respectivelyuntil the maximum pump speed of100% is reached. The response of the controller canbe adapted by means of the parameter "Raise".If the adjusted switch-off temperature is under run(DT F/DT1F/DT2F/DT3F), the controllerswitches off.Please note: Switch-on temperature difference DOmust be at least 0,5 K higher than the switch-offtemperature difference DF.MED%:Concentration of antifreezein (Vol-)%.MED% is blinded outby MEDT 0 and 3.Adjustement range:20 ... 70Factory setting: 45kWh / MWh:Heat quantity inkWh/MWhDisplay channelDT 0 / DT10 / DT20 /DT30:Switch-on temperatureAdjustment range:1.0 ... 20.0 KFactory setting: 6.0DT F / DT1S / DT2S /DT3F:Switch-offtemperature differenceAdjustment range:0.5 ... 19.5 KFactory setting: 4.0 KDT S / DT1S / DT2S /DT3S:Nominal temperaturedifferenceAdjustment range:1.5 ... 30.0 KFactory setting: 10.0 KRIS / RIS1 / RIS2 /RIS3:RaiseAdjustment range:1 ... 20 KFactory setting: 2 K51 VELUX
