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)
3.1.1 Control components
The modular design of the hardware allows for adding
optional equipment to expand the functions of
FSL

CONTROL II controllers must
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).
