Fan Coil operating mode: 2 control values/1 valve / with switching object
What does the option control value input: "2 control values/1 valve / with switching object" mean?
Example: Valve and three-speed fan
Control value processing in the device
Output A
Output B
Output C

 = Control value functions
- = Control value does not function
If the option 2 control values/1 valve / with switching object is selected, the control values will operate on
output A.
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.
