NOTE!
In the event of a controller malfunction, the "Collective failure" light on the TSS or TS panel and
the MAC-FC controller issues a fault signal to the CSP. If a controller malfunction is detected,
inform the SMAY service immediately. Do not repair or replace the controller yourself. This can
only be done by SMAY service or an authorised SMAY service.

Anti-Frost system
iSWAY- FC has introduced a system to prevent the shut-off dampers from freezing in
extremely low temperatures. Special low-temperature seals are used to seal the dampers, which
are resistant to low temperatures currently used in the refrigeration industry, also a directional
infrared heater system is used. When operating at a temperature below the set temperature, the
Anti-Frost system switches on automatically. The iSWAY-FC components are painted in different
colours to ensure adequate absorption or reflection of radiation.
The Anti-Frost system is powered by 230VAC.
