Hi,

I’ve got a Riello NXHM 8kW HP with emonHP, all working well. This is a Midea M-Thermal clone…

Currently, I’m controlling the HP via some code I’ve written to tap into the modbus via the controller. All working well except for one (critical) value… when NOT in weather comp I cannot figure out what register to write to to set the flow temp… I can set the different curves (when in weather comp mode) just fine… switch on heating/cooling/DHW etc just fine. 

Any help on this would be really appreciated, I’m sure I’m just not understanding the meaning of a register somewhere…

Thanks!
