6.2.2.5 Variable adaptation of hydraulic parameters (variable inputs and outputs)
The hydraulic settings preselected via the parameter hydraulic selection for the variable inputs and outputs
can be adapted individually. To this end, the preselected hydraulic parameters can be changed individually.
This enables hydraulics, which are not covered by the automatic factory settings, to be realized.
Caution The plant is defined by the hydraulic parameter. A change can have profound
effects on the operation of the controller. Preselected parameter settings can
be lost at other locations.
Therefore, individual adaptations must be carried out carefully!
Description: Only the inputs and outputs in the hydraulic level which can be accessed via the
controller are available for these settings.
The setting of the hydraulic parameter determines the function of the
corresponding output.
Example: PARAMETER 05 determines the output for the unmixed circuit pump. The factory
presetting for this output is HC.
If this output is assigned the function "circulation pump", the function HC is no longer
available.
The operation of a function is only possible, if the corresponding function is also
available hydraulically.
Example: The parameter for the setting of the circulation pump function is only available after
the function "circulation pump", for example, is assigned to the output HC.
If a variable function requires an input value (sensor) then it is assigned to the
corresponding variable input. Afterwards, this input can not be changed manually.
If settings were already assigned to the corresponding input, these will be replaced
and the corresponding functions will be reset.
Example: A second outdoor sensor has been assigned to variable input 1. Then the function
"buffer charging pump" is assigned to variable output 1. The variable input is initially
reset automatically (AF 2 is no longer active). Subsequently, the buffer sensor is
assigned to it, this is required for the correction.
