BT08L005GB-01PACKAGED362 - 904FC - THERMAL FREE COOLING (construction configuration C)As soon as external conditions allow it, the unit is capable of automatically activating free-cooling mode, which, bykeeping the compressors off and drawing in suitably filtered fresh air, cools the served room. The fresh air flowcan be varied based on actual needs. This operating mode is especially useful in spring and autumn or with highambient loads. It allows substantial reduction of the unit's energy consumption and wear of the compressors.CONFIGURATION CODE(1)(2) (3)(4)(5)(6)(7)CRH - XHE C 452 M 200R100SMSRBSMSRCRMRRHMHR(1) CONSTRUCTIONAL CONFIGURATIONrecirculated/outside air mixing box (B)free cooling version with extract/recirculated/fresh air intake box (C)(2) SUPPLYStandard (S)(3) OUTLET STATIC PRESSURE VALUEOUTLET STATIC PRESSURE VALUE(4) RETURNStandard (S)(5) INTAKE STATIC PRESSURE VALUE(6) AIR FLOWStandard air flow (SM)Reduced air flow (RM)Air flow high (HM)(7) INTAKE AIR FLOWStandard air flow (SR)Reduced air flow (RR)Air flow high (HR)FILTRATIONStandard units are standard equipped with a suitable filtering sectioncomposed of pleated filters, class G4, with an ample surface. They are easilyaccessible for periodic maintenance.UPDATED ELECTRONIC CONTROLThe operation of the unit is fully automatic thanks to the Clivet Talk electronicadjustment system. This is a modular device, of automatic origins, with highspeed and reliability and control logic specifically designed for this type ofproduct. The user interface is easy to use. This allows better use of availableresources, extending the life cycle of the components and thus reducingmaintenance costs. With the micro-processor keypad, it is possible to performdaily/weekly programming of the set-point, as well as start-up or shutdown ofthe machine. The unit can also be connected to supervision systems usingclean contacts or by serial with the standards of communication mostcommonly available on the market.CONTROL LOGICS IN THE EVENT OF ALARM SIGNALMachine logics(1)Complete shutdown(2)Room kept depressurizedDescription Standard Version Vers.
