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.

CONTROL OF THE 3-WAY VALVE FOR SANITARY HOT WATER Sanitary hot water can be produced in summer and winter, based on an external request, by controlling a dedicated 3-way valve. When the contact is closed, the valve switches to the sanitary hot water storage and the unit changes its working set point to the sanitary hot water set point (par 117).

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 .
DUAL CONTROLS FOR TEMPERATURE – RADIANT PANELS With the optional kit, a mixed plant can be controlled: Fan coil (with the set-points seen above) Radiant panels (with specific radiant set-points) The radiant set point can be determined in different ways, for further details see the ELECTRICAL CONNECTIONS section. FUNCTIONING WITH ETHYLENE GLYCOL The units foreseen to function with glycoled water come out from the premise with standard parameters.
SELECTING OPERATING TEMPERATURE COMFORT : to select the COMFORT temperature for the current operating mode, press the COMFORT key. The set point is only displayed on the machine. When this mode is activated, the led to the left of the key lights up and remains alight. ECO : to select the ECONOMIC temperature for the current operating mode, press the ECO key.

ALARMS BEFORE RESETTING THE ALARM, IDENTIFY AND ELIMINATE THE CAUSE OF ITS ACTIVATION. REPEATED RESETS CAN CAUSE IRREVERSIBLE DAMAGES. The ALARMS show a potentially dangerous situation for machine safety. Before resetting the alarm, discover and remove the cause: repeated resetting could cause irreversible damage. To avoid this, the unit can only be reset MANUALLY from the keyboard (only when the cause for the alarm has been removed).
ROUTINE MAINTENANCE BEFORE UNDERTAKING ANY SORT OF MAINTENANCE OR CLEANING, DISCONNECT THE ELECTRICAL POWER SUPPLY TO THE UNIT, AND ENSURE THAT OTHER PEOPLE CANNOT RE-CONNECT IT . All equipment is subjected to wear out. cleaning activities; otherwise, controls have performed by specialized technicians (INSPECTIONS).

REFRIGERANT TABLES THIS SECTION IS DEVOTED ONLY TO QUALIFIED TECHNICIANS THAT KNOW THE FOLLOWING: • THE OPERATIONAL PRINCIPLES OF THE REFRIGERATING CIRCUIT OPERATION • THE MODES OF DETECTING TEMPERATURE AND PRESSURE • THE RISKS RELEVANT TO THESE OPERATIONS The data of the tables allow the testing of the refrigerating circuit operation by the detection of a few objective parameters. The data are significant if they are detected simultaneously and while the refrigerating circuit is running.
TROUBLESHOOTING THE OPERATIONS MUST BE CARRIED OUT BY TECHNICAL QUALIFIED PERSONNEL HAVING THE REQUISITES UNDER LAW REQUISITES AND IN CONFORMITY WITH THE SAFETY REGULATIONS IN FORCE. THE INTERVENTIONS WITHIN THE WARRANTY PERIOD WILL BE CARRIED OUT BY AUTHORIZED SERVICE CENTERS. BEFORE RESETTING AN ALARM, IDENTIFY AND ELIMINATE ITS CAUSE.
