3 Control of ventilation units
3.1 FSL‑CONTROL II
System overview
FSL‑CONTROL II is a dedicated single room control
system for decentralised TROX ventilation systems.
FSL‑CONTROL II can be used to combine the following
control strategies:
Room temperature or extract air temperature control

Room air quality control (optional)

16 Single room control system FSL‑CONTROL II

3.1.1 Control components

The modular design of the hardware allows for adding
optional equipment to expand the functions of
FSL‑CONTROL II.

A group of FSL
include at least 1 master. This group may include up
to 14 slaves.
A plug-in communication cable (plug and play) is
used for the communication between master and
slave devices (at least cat. 5; the cable is not
included in the supply package).
