A sequence is activated by assigning either a load output or pump output to it. If
none of the 2 is assigned to a sequence, this sequence and all subsequent
sequences are inactive.
15.1.2 Load outputs
Load outputs are:
 Modulating output A…D
 Heat recovery equipment
 Mixing damper
 Step switch 1…5
Only one load output can be assigned to each sequence. Each load output can be
controlled by max 2 to 3 sequences (depending on function block).

The sequence controller is not suited for delivering more cooling via the second fan
speed because supply air temperature control overrides the sequences!
A second room temperature controller step can be entered directly at the cascade
controller (see section 11.6.3).
