yes there is indeed something in the source code there.. but it is only the setpoint almost like a thermostat.
in my code i presented three values. two of these values where not recognised as could be seen in the last post. but the last value was indeed a temperature setting and was recognised as a thermostat.
i guess i will post this to domoticz and hopefully it will be implemented 
Thanks you guys for the help!
i will post back here if i find anything usefull or when it is working just so others can find it.
