(a) Nominal cooling capacities are based on:
Eurovent: Indoor temperature: 27.0°C DB, 19.0°C WB. Outdoor temperature: 35°C DB. Eurovent 2015. Power input indoor units excluded.
T1: Indoor temperature: 26.7°C DB, 19.4°C WB. Outdoor temperature: 35°C DB. AHRI 1230:2010. Power input indoor units (duct type) included.
T3: Indoor temperature: 29.0°C DB, 19.0°C WB. Outdoor temperature: 46°C DB. ISO15042:2011. Power input indoor units (duct type) included.
T2: Indoor temperature: 26.6°C DB, 19.4°C WB. Outdoor temperature: 48°C DB. AHRI 1230:2010. Power input indoor units (duct type) included.
(b) Nominal and maximum heating capacities are based on indoor temperature 20°C DB, outdoor temperature 7°C DB and 6°C WB, equivalent
refrigerant piping: 5 m, level difference: 0 m.
(c) Actual number of units depends on the indoor unit type (VRV DX, RA DX, ...) and the connection ratio restriction for the system (50%≤CR≤130%).
(d) Nominal at 230 V.
(e) Sound values are measured in a semi-anechoic room.
(f) Sound power level is an absolute value that a sound generates.
(g) Sound pressure level is a relative value depending on the distance and acoustic environment. For more details, refer to sound level drawings in
the technical data book.

Power supply intake
(a) RLA is based on indoor unit temperature 27°C DB and 19°C WB, outdoor temperature 35°C DB.
(b) MSC=the maximum current during startup of the compressor. VRV IV-S uses only inverter compressors. MCA must be used to select the correct
field wiring size. The MCA can be regarded as the maximum running current.
(c) MCA must be used to select the correct field wiring size. The MCA can be regarded as the maximum running current.
(d) MFA is used to select the circuit breaker and the ground fault circuit interrupter (earth leakage circuit breaker).
(e) TOCA means the total value of each OC set.
(f) FLA=nominal running current fan. Voltage range: units are suitable for use on electrical systems where voltage supplied to unit terminal is not
below or above listed range limits. Maximum allowable voltage range variation between phases is 2%.
