Note: Only available when the "Device function" parameter is set on either
"Single device" or "Master device" and the "Control value type" parameter is set on "Fan
coil".
This parameter is used to specify when the output of the fan speed level values will occur
either only when the fan speed levels are manually adjusted or also in automatic mode.
This setting depends on the options for the fan coil actuator. If the actuator itself controls
the fan speed levels in automatic mode based on a derivative of the control value, then
the "Only for manual operation" option must be selected. Otherwise, the other option
should be selected.

Note: Only available when the "Device function" parameter is set on either
"Single device" or "Master device" and the "Control value type" parameter is set on "Fan
coil".
This parameter is used to preselect the lowest fan speed level that can be set by an
operation performed at the device. When level 0 is selected, the heating/cooling system
will not be in operation (fan speed level and valve control 0) as long as the current
operating state and operation type are maintained. To avoid damage to the building, level
0 is deactivated after 18 hours and the device is return to automatic state.

Note: Only available when the "Device function" parameter is set on either
"Single device" or "Master device" and the "Control value type" parameter is set on "Fan

The controller obtains the current fan speed level for controlling a fan coil actuator either
by calculating it from the table of level values under "Fan coil settings for heating" or "Fan
coil settings for cooling", or by receiving feedback from the fan coil actuator. If the "Yes"
