I get the following error during setting the entity heating curve.
This occurs for any number I choose.

I don't have a VRC700 controller, so I don't know what setPoint is supposed to be exactly in the context of the heating curve. Could you try reverse engineering to find out what values are being sent for VRC700 systems when updating the heating curve? I suppose it could be either the min flow temperature setpoint, or the max outdoor temp for heating.
