how to change heating set point using vera interface with only 1 button?

I installed a benext heating control unit which controls my (both opentherm) thermostat and heating unit.

This works fine, when i give lua code commands to set a new heating point (temp) this works also great, the thermostat nicely changes to the new set temparature, also the current temp of the room where the thermostat is located is displayed.

The only thing i am not sure of is how i can change the temperature in the vera UI(7) itself, I can change the temperature of the thermostat but i always have to press after changing the temp (with arrow up/down) the ‘heat’ button to activate/set the new heating point before it actually starts heating/cooling.

I am looking for a way for changing the temp using the GUI (ui7) directly when i press the +/- buttons of the thermostats widget and without to having to press the ‘heat’ button, so after pressing + or - it should immidiatly update/set the heating point of the thermostat.

Is this possible, if so how?
As mentioned, when i use lua code to change the temparature there is no need to press ‘heat’ or give an extra command to activate it, it does immidiatly starts heating to the new temp.

A second question.
Is there a way when i change on the thermostat itself the temperature it will update the heat setpoint in vera aswell?
When i now change the thermostat temp in vera it keeps showing my last set heatingpoint, not the new heatingpoint of the thermostat itself.
Must i change a setting to it will also read the thermostat heating point?
