IFFUSIONE MULTI 2188Diffusione Multi 21Top performance at the right priceOne unit, several roomsMulti stands for multisplit, a system that cancondition several rooms with a single outdoorunit. Diffusione Multi 21 is a dual split unitwhere two indoor units can be connected toa single outdoor unit: and this means greatconvenience and savings. Carefully deisgnedusing high-tech electronics and high efficiencycomponents. The use of environmentallyfriendly R410A gas and higher performanceefficiency, provide better protection for theenvironment.
Double-compressortechnologyDiffusione Multi 21 ensures thebenefits of climate control in severalrooms using a single outdoor unit.The double-compressor technologyfurther reduces power consumption,using one or two compressors tomeet demand. Moreover, if one ofthe two compressors fails, DiffusioneMulti 21 can continue operating withthe other one.FunctionsThe practical remote control withits large display, lets you select,among other things, the followingfunctions:Auto: the unit automatically setsoperation mode according to thedifference between the temperaturesetpoint and the temperature in theroom.Dry: this mode optimizes the airconditioning operation and fanspeed in order to absorb humidity.Sleep: the temperature setpointis increased (in cooling mode) ordecreased (in heating mode) by1°C per hour for the first two hours.Then the temperature setpointdoesn’t change for the next 5 hours,afterwich the unit is switched. TheSleep mode lets you maintain acomfortable temperature and, at thesame time, save power.Diffusione Multi 21 HPOS-C/SEMMH-21EIPower supply V-F-Hz 230-1-50Maximum operating pressure MPa 3,50Max connecting length m 15Max height difference m 5Additional gas (over 8 mt length) g/m 20Power cable (W pole) — 3Outdoor unitOS-CEMMH21EIDimensions (W x H x D) mm 895x655x345<strong>Air</strong> flow (max) m 3 /h 2200Fan speeds rpm 830Refrigerant gas/charge Kind/Kg R410A/2,000(1,10+0,90)Sound level db (A) 56Weight (without packing) Kg 76Indoor unit OS-CEMMH09EI OS-CEMMH12EIDimensions (W x H x D) mm 710x250x195 790x265x193<strong>Air</strong> flow in cooling mode (max/med/min) m 3 /h 500/460/410 500/430/370<strong>Air</strong> flow in heating mode (max/med/min) m 3 /h 500/460/410 500/430/370Fan speeds rpm 1200/950/850 1220/1000/800Ø Connecting pipe (liquid) inch-mm 1/4”-6,35 1/4”-6,35Ø Connecting pipe (gas) inch-mm 3/8”-9,53 1/2”-12,7Connecting cable (N° pole) — 4 4Sound level db (A) (max/med/min) 36-34-32 37-34-31Weight (without packing) Kg 8,0 9,0OPERATIONAL LIMITSMaximum operating temperature in cooling mode:Indoor temperature DB 32°C - WB 24°COutdoor temperature DB 43°C - WB 26°COPERATIONAL LIMITSMaximum operating temperature in cooling mode:Indoor temperature DB 17°C - WB 14°COutdoor temperature DB 15°COPERATIONAL LIMITSMaximum operating temperature in cooling mode:Indoor temperature DB 27°COutdoor temperature DB 15°CThe technical data are referred to EN 14511.HP = heat pumpHE = high efficiency (energy savings/high performance)TEST PARAMETERS(1) Cooling capacity test:Indoor temperature DB 27°C - WB 19°COutdoor temperature DB 35°C - WB 24°C(2) Heating capacity test:Indoor temperature DB 20°C - WB 15°COutdoor temperature DB 7°C - WB 6°CConfiguration OS-CEMMH21EI + OS-CEMMH09EI + OS-CEMMH12EINominal absorption in cooling mode (1) A 8,9 E.E.R. — 3,01Nominal absorption in heating mode (2) A 9,0 C.O.P. — 3,41Yearly energy consumption in cooling mode (1) kWh 1.023 Energy Efficiency Class in cooling mode — BDehumidification capacity l/h 3,2 Energy Efficiency Class in heating mode — BOPERATIONAL LIMITSMaximum operating temperature in cooling mode:Indoor temperature DB 17°COutdoor temperature DB -15°C89
