UNIT IDENTIFICATION SERIAL NUMBER LABEL The units are identified by the serial number label shown here. The label lists the type of unit (series and size), serial number, year of manufacture, number of electrical diagram, main technical data, logo and address of the manufacturer. The label is placed on the unit, generally near the electrical panel and also on the external panelling.
INSTRUCTIONS FOR THE USER • This is a partial sintex of the information provided in the manual; carefully read this manual • Carefully read this manual. Keep it with the electrical diagram. Make it available to technicians for servicing. • Ask the installer for training on start-up, shutdown, changing set points, placing in at-rest status, maintenance, what to do or not to do in the event of a breakdown.
CE MARK Perform the operations in conformity with the local regulations in force. Clivet products bear the CE mark, in compliance with the PERIODICAL INSPECTIONS requirements of the following EC directives, including the Perform periodical inspections to locate possible loosened latest amendments, and with the corresponding national or broken parts.
RESIDUAL RISKS and precaution is taken when positioning and securing the GENERAL unit. This section lists some of the more common situations If the unit is easily accessible to children, unauthorized which, being beyond the control of the manufacturer, could persons or animals, this is a situation that can give rise be a source of risk to persons or property.

FUNCTIONAL CONNECTIONS FOR ALL THE CONNECTIONS MAKE REFERENCE TO THE ELECTRICAL PANEL SUPPLIED WITH UNIT Use voltage-free remote control devices that are suitable to commutate very low loads (12V, 10mA) Few inputs must be activated by configuration parameters whose access is reserved to authorized assistance centres (in order to avoid unauthorized modifications) ON / OFF FROM REMOTE CONTROL Generally the unit is delivered with bridged terminals;...
SET POINT COMPENSATION ON THE TEMPERATURE OR EXTERNAL ENTHALPY Optimises unit energy efficiency by automatically adjusting the set-point according to enthalpy or the external temperature. Requires the external humidity probe or the external temperature probe, which are optional for certain types of units and must be installed by the customer and enabled by parameters 152=1 and 156=1.

SET-POINT COMPENSATIONS The compensations are evolved functions to protect the compressors and to adapt, as far as possible, the unit operating to the installation and use characteristics. The compensations prolong the compressor operating time and limit the start number; to do this they delay the compressor insertion point adding an offset.
DEFROSTING The defrosting aim is to maintain the external coil free from ice during the winter mode : to do that the unit is periodically commuted in “summer” mode for few minutes and the fans are stopped. The defrosting phase is started when the evaporating pressure falls below a fixed value . A count starts and at its end, if the temperature on the coil is lower than the threshold, the defrosting starts .
MAINTENANCE This way, the plant can be kept within the operating limits even when the unit is OFF or on STANDBY, for example during the weekend or the nighttime. Periodically the system activates the circulation pump, measures the water temperature and activates the compressor, if required, to take the water temperature to the set-point level.
