● The output for the 1
st
stage (YHC1) in heating mode is also the 1
st
stage in
cooling
● This function is available for DC/3-speed/1-speed fans
We recommend enabling the swap function on applications with fan coil units and
floor heating/cooling. In this application, the fan runs during cooling demand (fan
coil unit and floor cooling) and only in the 2
nd
heating stage (with the fan coil unit).
Set P254 to On or Off, depending on the selected control signal (swap function),
and set P350 to 4 (fan in the 2
nd
stage).
The fan runs during heating demand and only in the 2
nd
cooling stage, e.g. for
applications with fan coil units and radiant heating/cooling panels.
This setting is available only when P350 is set to 5, and the swap function is
selected (P254 to On or Off).
Example 2:
P350=4
Example 3:
P350=5
