Control Functions

Only those inputs and outputs that are actually present on the
controller are available for setting in the "Hydraulics" menu.
The function of the corresponding output is determined by the
setting of the hydraulic parameter.
Example:
Parameter 05 defines the function assignment of the output for
the direct heating circuit pump (DHCP). Ex works, this output is
set to the corresponding setting for the direct heating circuit
pump.
If this output is assigned the "circulation pump" function, the direct
heating circuit pump function is no longer available.
A function can only be executed if the corresponding function is
also available in the hydraulic system.
Example:
The parameters for setting the circulation pump are not
accessible until the direct heating circuit pump output is assigned
to the "circulation pump" function, for example.
If a variable function requires an input value (sensor), then this
sensor will be assigned to the matching variable input. This input
can then no longer be changed manually.
If individual settings were previously made for the associated
input, they are overwritten and the corresponding functions are
reset.
Example:
A second outside sensor is assigned to variable input 1. The
"buffer loading pump" function is now assigned to variable output
1. The variable input is now reset automatically (outside sensor 2
no longer active). The buffer sensor is then assigned to it, as it is
required for correction.
