GENERAL FEATURESUnit descriptionThis series of air-water heat pumps satisfies the heating,cooling and domestic hot water production requirements ofresidential plants of small and medium size.All the units are suitable for outdoor or indoor installation andcan be applied to fan coil plants, radiant floor plants and highefficiency radiators plants.The control system allows to manage not only the refrigerantcircuit but the whole plant with the possibility to choose differentsolutions both for the heating and cooling plant and for thedomestic hot water management. The possibility of solarpanels or other heating sources integration is also available.The heating function optimizes the flow water temperatureaccording both to the ambient temperature and to the outdoortemperature through climatic curves adaptable to the buildingfeatures. It’s possible to manage a storage tank and two independentcircuits (a direct one and a mixed one).The domestic hot water management allows to control thethree way valve, the storage tank and the anti-legionellacycles (if necessary).The cooling function can be realized through “active cooling”(refrigerant circuit inversion). When the unit is used in radiantfloor plants, to avoid condensate generation, a room humiditysensor can be installed.The internal programmer clock allows to define differentdaily switching programs for heating, cooling and domestic hotwater production.The refrigerant circuit, contained in a box repaired from the airflow to simplify the maintenance operations, is equipped withscroll compressor mounted on damper supports, brazed plateheat exchanger, electronic expansion valve, reverse cyclevalve centrifugal fan (plug fan), finned coil realized with copperpipes and alluminium fins. The circuit is protected by highand low pressure switches and flow switch on the plate heatexchanger.The plate heat exchanger and all the hydraulic pipes are thermallyinsulated in order to avoid condensate generation andreduce thermal losses.The plug fan with electronic control of the rotational speedguarantees high efficiencies and low noise in all the operatingconditions and allows to install the unit both outdoor (with protectioncaps) or indoor (with ducted air inlet and outlet).All three-phase power supply units are provided with a phasesequence and correct sequence controller device.All the units are accurately built and individually tested in thefactory. Only electric and hydraulic connections are requiredfor installation.Unit identification codeThe codes that identify the units and the meaning of the letters used are described below.HXP IP 16.1 VB AB 0 M 1Unit typeIP - Units suitable forhydronic plant installationoperating as reversible heatpumpsUnit versionVB - Base VersionUnit modelN° compressorsAcoustic setting upAB - Base setting upPower supply1 - 230V - 1 - 50 Hz5 - 400V - 3N - 50 HzOperating rangeM - Medium temperature.The unit is suitable to producewater at medium temperatureRefrigerant type0 - R410A5
