The second opportunity of the manual setpoint offset is the movement of the setpoint depending to
the adjusted

setpoint. Sending a negative Kelvin value at this object causes a decrement of the adjusted setpoint.
By sending 0K the setpoint, which is adjusted in the parameters is active again. From Hardware
Version 2.0, it can be adjusted if the manual setpoint value offste should be performed by 1 Byte or 1
Bit command.
By activating the Setpoint offset with setwheel at the device-specification with setwheel, the

offset is performed by the setwheel now (have a look at 4.1.1).
