﻿The number of usable fan levels depends on the configuration of the FanCoil system on the General HVAC parameter page. 
If the fan is controlled "switching via relay outputs", the number of fan levels is configured on the General HVAC parameter page and the number is only shown here for information purposes. 
With "continuous via 0...10 V outputs" control, configuration takes place at this point.

In the configuration with only one fan coil channel a maximum of 5 fan levels can be used. If two FanCoil channels are parametrised, whether three or five fan levels are available depends on the fan control.
