VERSIONS
OPERATION
Inbothversions,theunitpullsairoutfor70seconds,thenitpushesairinforthesametime.
Whenheatedairispulled(extracted)frominsidetheroom,itwarmsuptheheatexchanger;whenthecoldairispushed(supplied)intheroom,itgets
preheated,recoveringmostofthermalenergywhichwouldbeotherwiselostintheventilationprocess.
Theunitrunsatthespeedselectedbyactivatingthetwo-positionswitches“S1”,“S2”and“S3”oftheCTRL-S(accessoryg.57).Thesamefunctionality
canbeachievedwithCTRL-Sorwith3two-positionswitches.
S3switchactivatesthe“Freecooling“(Bypass)mode,whichstopsalternateowandkeepsthefanin“extract-only”or“intake-only”mode,toavoid
theheatexchangewhennecessary.Tosettheextract-only”modeor“intake-only”,placetheintegraljumpersasperg.20A-20B).ThefrontcoverLED
indicateswhentheFreecoolingmodeison.
Anautomatic“Boost”modecanbeachievedthroughadedicatedswitchorroomsensorslikeSEN-HY,SEN-PIRorSEN-CO2,connectingsuchswitch
inparalleltotheS2switch.

WARNING:
Ensure that the electric wiring to L and N is done correctly.
An incorrect connection will lead to malfunction or permanent damage of the fan.
Whentheunitsareinstalledinpair,theymustbesynchronisedsothatwhenoneunitisextracting,theotherissupplying,andviceversa(g.18E-18F-
18G).
Thisisachievedbysettingthededicatedjumper(g.20A-20B).
RESET OF THE SYNCHRONISATION
OPTION1:Iftwoormoreunitsareconnectedunderthesamemainswitch,toresetthesynchronisation,themainswitchmustbeswitchedrstOFF
andthenONtoreactivate(g.31).
OPTION2:Iftwoormoreunitsarenotconnectedunderthesamemainswitch,toresetthesynchronisation,pressatthesametimetheblackpinof
eachunit(g.33)foratleast3seconds.
SYNCHRONISATION
Iftwoormoreunitsarecontrolledbymeansofthesamecontroller(CTRL-Sorsimilar),theyalwaysoperateinasynchronisedway.Wiringdiagram
asperg.18D.
SYNCHRONISATION IN CASE OF INSTALLATION WITH CONTROLLER
IntergaljumpersetinpositionA(g.20A)means“extract-only”mode.
IntergaljumpersetinpositionB(g.20B)means“intake-only”mode.
Thejumperpositiondenesboththeair-owdirectionwhentheunitisactivatedforthersttime(forthesynchronisation)andtheair-owdirectionof
the free-cooling mode.
