﻿The device can determine the largest constant command value and forward it to another bus device (e.g. suitable calorific furnaces with integrated KNX control or visualisation). In the "active" setting, the device evaluates all 1-byte command values of the valve output and, optionally, the externally received largest command value and transmits the largest command value via the "Largest command value" object.

In the case of command value data formats "Switching (1-bit)" or "Constant (1-byte) with command value limiting value", there is no evaluation of the command values preset via the bus. Exception: It may also occur with such command value outputs that a constant command value is active (e.g. after voltage return or a forced position and emergency operation). In this case, this constant command value is also included in the calculation of the largest command value until the named functions with a higher priority are exited or a new command value telegram is received internally, overriding the constant command value at the valve output.
