If the option 2 control values/2 valves / with switching object is selected, the control values will operate
directly on output A (B) and output C (D).
Which of the two control values operates on outputs A and C is decided via the communication object
"Toggle heating".
The function of the two fans EFG control values A and B is set in the application. In this example, "Number
of control value inputs" is parameterized to 2 and the reaction to "Largest value".
To ensure correct operation of the Fan Coil, the fan EFG control value A is connected with the control
value cooling and the fan EFG control value B with the control value heating.
Note
In the option 2 control values/2 valves (with or without switching object), one valve must be
parameterized as a heating valve and the other as a cooling valve, according to the installation
conditions.
