UATYA
4P645202-2
The unit is equipped with a refrigerant detection system that complies with Annex LL of the IEC 60335-2-40:2018,
which position has been checked according to test reported in Annex MM of IEC 60335-2-40:2018.
When the refrigerant detection system detects a leak, the following will be initiated by the unit:
• disable the compressor operation unless the compressors;
• Supply and return (if present) fan control will be set to to constant airow logic with a x airow value. The fans
will operate continuously even if time tables are set. This in order to not let the airow to go below "Q
min
" (see
below);
• Energize a dedicated relay in the electrical cabinet in order to fully open any external zoning dampers;
• Set the dampers (if installed on the appliance) in order to have a full intake of fresh air and a full expulsion of the
return air.
External zoning dampers, if present, must be connected to this relay in order to be open when a leak
is detected
Zoning dampers installed in rooms considered to determine the minimum room area must be
electrically powered at all times after installation, other than when servicing, to be eective for safety.
The refrigerant detection system and controls will maintain the above action until at least 5 min after the refrigerant
detection system has reset. Building re and smoke systems may override this function.
If the leak detector detects a leak, the above operations will be initiated even if the unit is turned OFF
by button, by BMS or by digital input.
In addition to what above another dedicated relay is present in the unit electrical cabinet and
connected directly to the leak detector alarm. This relay can be used to monitor the leak detector
alarm even in case of a unit control board fault.
The minimum circulation airow (Q
min
) circulated to the total conditioned space, expressed in m
3
⁄h, must be in
accordance with the following table:

Whenever the ow, measured by the dierantial air presssure tranducer, falls below the values
reported in the table above, the airow alarm from dierential pressure transducer will be displayed on
the unit control and the unit will be stopped.
The supply and return air shall be directly ducted to the conditioned space. Open areas such as false ceilings shall
not be used as a return air duct.
