4. User interface
Thisoperationmanualwillgiveanon-exhaustive
overviewofthemainfunctionsofthesystem.
Detailedinformationonrequiredactionstoachieve
certainfunctionscanbefoundinthededicated
installationandoperationmanualoftheindoorunit.
Refertotheoperationmanualoftheinstalleduser
interface.
5. Operation range
Usethesysteminthefollowingtemperatureand
humidityrangesforsafeandeffectiveoperation.
Outdoortemperature –5~52°C DB
–20~21°C DB
–20~15.5°C WB
Indoortemperature
21~32°C DB
14~25°C WB
15~27°C DB
Indoorhumidity ≤80%
(a)
(a)
To avoidcondensationandwaterdrippingoutoftheunit.
Ifthetemperatureorthehumidityisbeyondtheseconditions,
safetydevicesmaybeputinactionandtheairconditionermay
notoperate.
Aboveoperationrangeisonlyvalidincasedirect
expansionindoorunitsareconnectedtotheVRV
system.
6. Operation procedure
• Operationprocedurevariesaccordingtothe
combinationofoutdoorunitanduserinterface.
Readthechapter“3. Before operation”.
• Toprotecttheunit,turnonthemainpower
switch6hoursbeforeoperation.
Anddonotturnoffthepowersupplyduringthe
airconditioningseasonbecauseofsmoothly
startup.
• Ifthemainpowersupplyisturnedoffduring
operation,operationwillrestartautomatically
afterthepowerturnsbackonagain.
6.1 Cooling, heating, fan only, automatic
operation and dry operation
• Theoperationmodecannotbechangedwith
theremotecontrollerwhosedisplayshows
“ ”(changeoverundercentralizedcontrol).
Changetheoperationmodewithuserinterface
whosedisplaydoesnotshow“ ”.
• Whenthedisplay“ ”(changeoverunder
centralizedcontrol)ashes,referto“6.4 Setting
the master user interface’’.
• Thefanmaykeeponrunningforabout1minute
aftertheheatingoperationstopsforremoving
theheatintheindoorunit.
• Theairowratemayadjustitselfdependingon
theroomtemperatureorthefanmaystop
immediately.Thisisnotamalfunction.
