7.5.10 Definition of mixed circuit operating

The mixed circuit can be used for different systems in heating and
cooling mode.
The setting influences parameters for
- Minimum and maximum temperature in heating and cooling mode
- Slope of the heat curve

7.5.11 Links between mixed circuits and manifolds

Fig. 7-20 Webpage: Mixed circuits and manifolds
In this example, manifold 1 is used for underfloor heating, manifold 2
for ceiling cooling.
Note:
It is not a problem, that both manifolds are directly connected to the
mixed circuit. There is no need to install valves which close one of the
pipes in heating and another pipe in cooling mode. It would be also
possible, to use one manifold for heating and cooling.

Input / output assignment of U-Modules for dehumidifiers

One U-Module can control 2 dehumidifiers.
When dehumidifiers are used which have an additional coil for cooling
the intake air, REL 1 and REL 3 are used for opening a valve for each
dehumidifier.
The manifold to which these valves belong have to be defined.

When you use "Confirm & test", the outputs can be switched:
