Display of low load levels
Both circuits are shown separately in bars (see Picture 35). The subdivision is based on the
edited low load device levels (

). Locked levels are white and unlocked levels are green.
Low load - Setpoint output

Via bus
By default, all speed setpoints are transferred to the fans via MODBUS when using the
low-load control. It is also possible for individual fans or fan groups to be selected and
deselected.

Via analogue output
A second possibility (if there is no bus communication with the fans) is a speed output
for two low-load device levels via the two analogue outputs of the basic unit TCS.2. The
following steps are necessary to activate this function:
1. Select a type of control (Device settings -> Control (see chapter 4.2.10 “
Low load
regulation control
”)
.
2. Select “Control 0-10 V DC” in the “Fan settings” menu (see chapter 4.4.1 “
Control
of the
fans”).
3. In the “Analogue OUT basic unit” menu, set both analogue outputs to “Speed circuit
1, 0-10 V” or “Speed circuit 1, 2-10 V” (see chapter 4.3.4 “
Analogue OUT basic
unit
”).
With these settings, the first analogue output (AO-1) works as a low load basic level and
the second analogue output (AO-2) as a low load control level.
As a result, both analogue outputs must be wired separately with the corresponding fans or
fan groups.
