temperature at startup of VWL 75/6

[avanmourik]

When my heatpump is started, the ZWZ AI indicates a desired value for the water temperature to the heating circuit. So far I have not been able to find the required line in the ctlv2 configuration file to log this setpoint. Once the pump is running the setpoint is gradually lowered (modulation) to match the setpoint given by the heating curve.
Doe anyone know which variable I should use to monitor this

Hi,
ebusctl read SetMode
returns
auto;39.5;-;-;0;1;1;0;0;0
39.5 is target value

---

ebusctl read Status01
39;34.5;-;-;-;on

current temp 39
return flow 34.5

Dear ralfnap2,
Thanks for your reply
Great! There is a way to get to the desired value.
However the message definition of SetMode seems not present in the repository files 8.hmu.csv or15.ctlv2.csv.
( https://github.com/john30/ebusd-configuration/tree/master/ebusd-2.1.x )
Can you also provide the message definition for SetMode, so that I can include it in my csv file?
Thanks in advance

Hi avanmourik,
the line is not in 8.hmu, it is in include file hcmode.inc

Hello ralfnap2,
Thanks for your help.
I had included the hcmode file, but discovered it was not loading due to errors.
After having solved most of the errors, I now get the desired values
hmu SetMode = auto;52.5;-;-;0;1;1;0;0;0
hmu Status01 = 42.5;37.5;-;-;-;on
Will monitor this for a while and then close the issue
