With a permanently active command value limit, the initialisation behaviour cannot be
configured separately after a device reset, as the limit is always active. In this case it is also not
possible to configure any object.
As soon as the command value limit is active, calculated command values are limited according
to the limiting values from the ETS. The behaviour with regard to the minimum or maximum
command value is then as follows...
- Minimum command value:
The "Minimum command value" parameter specifies the lower command value limiting
value. The setting can be made in 5 % increments in the range 5 % ... 50 %. With an active
command value limit, the set minimum command value is not undershot by command
values. If the controller calculates smaller command values, it sets the configured minimum
command value. The controller transmits a 0% command value if no more heating or
cooling energy has to be demanded.
- Maximum command value:
The "Maximum command value" parameter specifies the upper command value limiting
value. The setting can be made in 5 % increments in the range 55 % ... 100 %. With an
active command value limit, the set maximum command value is not exceeded. If the
controller calculates larger command values, it sets the configured maximum command
value.
If the limit is removed, the device automatically repositions the most recently calculated
command value to the unlimited values when the next calculation interval for the command
values (30 seconds) has elapsed.
i If the controller executes a valve protection function, the command value limit is temporarily
deactivated in order to make use of the full motion range of the valve.
i An active command value limit has a negative effect on the control result when the
command value range is very restricted. A control deviation must be expected.
