Thecircuit is protected by a safety gas valve,high and low pressure switches and differentialpressure switch on the plate heatexchanger. The plate heat exchanger andall the hydraulic pipes are thermally insulatedin order to avoid condensate generationand to reduce thermal losses.All the units can be equipped with variablespeed fans control that allows the units tooperate with low outdoor temperatures incooling and high outdoor temperature inheating and permits to reduce noise emissionsin such operating conditions.The low noise acoustic setting up (AS) isobtained, starting from the base setting up(AB), reducing the rotational speed of thefans and mounting sound jackets on thecompressors and the technical compartmentis clad with soundproofing materialof suitable thickness.The eXtra low noise acoustic setting up(AX) is obtained, starting from the low noisesetting up (AS), further reducing the rotationalspeed of the fans and using finnedcoil with bigger surface.All the units are supplied with a managementand control electrical panel containinggeneral switch, phase presence andcorrect sequence controller, microprocessorcontroller with display and all the otherelectrical components with IP54 minimumprotection degree.All the units are accurately built and individuallytested in the factory. Only electricand hydraulic connections are required forinstallation.OptionsCAStoring and pumping module available inthe configurations :• Storage tank arranged as buffer on theflow or as primary-secondary buffer• 1 or 2 pumps• standard or high head pump• modulating pumpExpansion valve• thermostatic• electronic (standard for IP)Compressor starting• standard (contactors)• soft starterFans control• on-off control• modulating control (condensation / evaporationcontrol)Compressor power factor correctionElectrical load protection• fuses• thermal magnetic circuit breakersCoil condensate trayAccessoriesRubber vibration dampersSpring vibration dampersCoil protection grillesTank antifreeze electrical heaterRemote controlModbus serial interface on RS485Programmer clockPhase sequence and voltage controllerLow temperature kit (standard for IP)High and low pressure gaugesHigh temperature thermostatCoil shut off valvesOutdoor air sensorWater flow switchVictaulic hydraulic fittingsCod.
