Fan control

For model RC-C3DFOC, the fan button will control the EC fan output to pre-set speeds and
then offer feedback to the user through the fan segment displayed. This takes place in the same
way as for other …F models.
When the fan button is pressed, it will step through the configured fan levels:

contains the text "Controller output for fan speed”. For an EC fan, this
signifies the output level for fan speed 1, 2 and 3. When in auto mode, the output is fully step
less.
Prevent manual fan control
This function prevents manual control of the fan when it is not desirable for it to be affected
by the Cooling/Heating output signal. If the fan is not activated and set to follow the
Cooling/Heating signal, it should not be possible to alter the fan speed manually. Please note
that if the fan configuration is set to not follow the cooling or heating signal and this function
is simultaneously active, the fan will not be controllable using the fan button.
This function works as described below:
Parameter 91 setting
Is manual fan control available?
If heating signal

cooling demand
No
No
1 = The fan is controlled by heating demand
Yes
No
2 = The fan is controlled by cooling demand
No

3 = The fan is controlled by both cooling and heating
demand

If the controller has a fan button (only applies to models with a display), fan control will return
to auto mode when the controller changes control mode from cooling to heating or vice versa.
If the controller has a fan switch (only applies to models without a display), fan control will
instead return to the current fan speed mode.
