Communication with meters Landis ULTRAHEAT

There are following variables on the Data-received page: Header of M-BUS message ActualityDuration (actuality duration [sec]), ResponseDuration (response duration [sec]), Energy (accumulated energy [GJ]), Volume (accumulated volume [m3]), Power (instantaneous power [kW]), Flow (instantaneous flow [m3/h]), TemperForward (Forward temperature [°C]), TemperReturn (Return temperature [°C]), TemperDiff (Temperature difference [°C]), VolumeMem1 (accumulated volume [m3] from last year), EnergyMem1 (accumulated energy [GJ] from last year), FabricNr (Meter fabric number), RespDurationTar1 (response duration [sec], Tariff=1), PowerMaxTar1 (maximum power [kW], Tariff=1), PowerMaxMem1Tar1 (maximum power [kW] from last year, Tariff=1), FlowMaxTar1 (maximum flow [m3/h]), Tariff=1), TemperForMaxTar1 (maximum Forward temperature [°C], Tariff=1), TemperRetMaxTar1 (maximum Return temperature [°C], Tariff=1), OnTime (number of days), OnTimeErr (number of days in error), OnTimeErrMem1 (number of days in error from last year), DataReading (date and time of reading, year is not available), EnergyTar2 / EnergyTar3 / EnergyTar4 (accumulated energy [GJ], Tariff=2/3/4), EnergyMem1Tar2 / EnergyMem1Tar3 / EnergyMem1Tar4 (accumulated energy [GJ] from last year, Tariff=2/3/4), TemperForMaxMem2Tar1 (maximum Forward temperature [°C], 1.value from last year, Tariff=1), TemperRetMaxMem2Tar1 (maximum Return temperature [°C], 1.value from last year, Tariff=1), FlowMaxMem2Tar1 (maximum flow [m3/h], 1.value from last year, Tariff=1), PowerMaxMem2Tar1 (maximum power [kW], 1.value from last year, Tariff=1), OnTimeErrMem2 (number of days in error, 1.value from last year), EnergyMem2 / EnergyMem2Tar2 / EnergyMem2Tar3 / EnergyMem2Tar4 (accumulated energy [GJ], 1.value from last year, Tariff=0/2/3/4), VolumeMem2 (accumulated volume [m3], 1.value from last year), Date (meter date and time), Microprogram (version), D0 (extended byte, perhaps always 0), D1 (extended byte, perhaps always 0), D2 (extended byte, 0.bit=1=preadmonition, 7.bit=0/1=instalation in return/forward line).

By this simple message it is possible to set the time in the meter. Date and time is set in the "Date" variable on the Data-sent page.
