Rooftop & Large Rooftop aessories & options Triple input eonomizer This system utilizes 3 probes: Return ir, utdoor ir and Supply ir. The utdoor ir damper and the Return ir dampers are mehanially interonneted in order to provide the same airflow at the oil inlet, with a single damper motor. The PB ompares sensor values and modulates the dampers providing maximum effieny of the eonomiser system (free ooling) and omfort (Supply ir > 12 ). ombined with the air quality sensor, your paybak will be ensured within few months. The rain hood is painted to math the basi unit and aluminium mesh preflter prevents water penetration. -^2 Indoor air quality This sensor measures onentrations of pollutant gases, suh as tobao smoke, human body odours, kithen odours, arbon monoxide, et It automatially overrides the eonomizer when pollutant levels rise above preset limits. shorting plug will set the algorithm to aeptable, good or very good air quality. This V sensor (Volatile rgani ompounds) sends an N/FF signal to the ontrol PB. The YKN2pen will then adjust the fresh air damper, optimising indoor air quality and minimising the energy onsumption. Motorised outdoor air damper Premium Kit - Low ambient ontrol Equipped with the same dampers as the eonomizer, the Return ir probe is not used. utdoor air damper opens to pre-set position whenever the indoor fan is operating (seleted from the thermostat, the indoor fan an be ativated with the ompressor or to operate ontinuously) and will drive fully losed when the indoor fan shuts down. The rain hood is painted to math the basi unit and aluminium mesh pre-flter prevents water penetration. ll our rooftops are designed to work in ooling mode down to 7 ambient temperatures. lthough this working range suits most appliations, the units an operate orretly down to -18 with optional Premium Kit. The Premium Kit option onsists on an E ondensing fan that will allow us to inrease the airfow at redued onsumption. lso we have ondensing and evaporating pressure ontrol that will extend our operating limits. It s estimated an inreased effieny by +.15% in EER and P. Enthalpy sensors High pressure drive & To ontrol the eonomizer in humid areas, or when indoor air humidity needs to remains dry, you should selet enthalpy regulation. Enthalpy sensors will be used with the triple input eonomizer. l HPDJ The high pressure drive will inrease the supply fan performane for appliations requiring greater air fow and/ or stati pressure. Please onsult tehnial guide for more information. Barometri relief damper Power Exhaust This aessory an be used to relieve internal air pressure on units equipped with triple input eonomiser or motorised air damper but no power exhaust. When the rooftop is working in free ooling or introduing fresh air, the damper opens to relieve over pressure from the return air setion. This aessory is omprised of a rain hood, a protetive grille and a fully assembled damper. Used to mehanially relieve internal air pressure from the Return ir setion and ensure effient fresh air introdution on units equipped with triple input eonomiser or motorised air damper. The power exhaust fan motor works when enough utdoor ir is blowing into the room and if utdoor ir temperature is aeptable (12 < t < 3 ). Fresh air damper and rain hood Smoke detetor The most ost effetive method with a omplete rain hood and a fxed damper that an be adjusted to provide approximately 1, 15 or 25% of fresh air. The smoke detetor is proteting the HU but must not be used to ensure a full building protetion against smoke danger. If smoke is deteted the HU is shutdown (lokout). manual reset is neessary. Fire detetion thermostat Dirty flter swith This fre detetion thermostat is proteting the HU but must not be used to ensure a full building protetion against fre danger. The standard HU is proteted as standard with a Supply ir probe that shuts the unit down (lokout) when temperature exeeds 8. The eletro-mehanial fre detetion thermostat is used to fulfl speif loal requirement. manual reset is neessary. Ensures that lean air is being supplied, advises when maintenane is required to prevent exessive depression and ensures water integrity of the HU. These are the main advantages of flter dirty swith. onneted with the DP-1 thermostat, the flter ion will appear on the thermostat sreen when a flter hange is required. SlYRK* 166 Johnson W 1 ontrols
