To functionally connect the unit, take the power cable on the electrical control panel inside the unit, fig. 1, and connect it with the disconnecting terminals, taking into account the phase, neutral and ground, both in the case of single-phase (230V~ 50Hz) and three-phase power supply (400V-3N~50Hz). To prepare the summer/winter switching device, connect the contact of the device to terminals 3 and 5 of the connection board X0. If, due to malfunctions, it is necessary to view the machine block at a remote point, this is possible via terminals 6 and 7 of the connection board X0.
To prepare a summer/winter switch device, connect the device contact to terminals 8 and 9 of the X0 terminal board. Whenever the KPSRP accessory is provided, the pump kit is already connected to the plant, but if another pump is required, connect it to Modu_control's XP. The intervention of this alarm determines the compressor block and not the pump block, which remains active together with the ignition of the resistor if installed.
Check the tightening of the screws of the compressors and the electrical box, as well as the outer casing of the unit. We recommend that you provide a hardware book (not included, but the responsibility of the user) that allows monitoring of interventions on the device. Use the date to record the date, type of intervention performed (routine maintenance, inspections or repairs), description of the intervention, actions taken.
It provides that the disposal of the unit is carried out in accordance with the standards in force in various countries. Some parameters in the moducontrol table should be set appropriately based on the type of system in which. The display shows the index of the USER parameter and a three-character string that identifies it.
The screen shows the index of the INSTALLER parameter and a string of three characters that identifies it. This parameter indicates the standby time for reversal of the 3-way bypass valve on the DHW production system. Remove the bracket attached to the base of the compressor before closing the front panel.

Maintenance
Extraordinary maintenance
Under normal conditions, they do not require technical assistance related to refrigerant gas control. Over time, gas leakage can be generated from the joints, causing refrigerant to escape and discharge the circuit, causing the appliance to malfunction. In these cases, the leakage points must be detected, repaired and the gas circuit must be refilled in accordance with the law of 28. December 1993 No. 549.
Empty and dry the entire cooling circuit using a vacuum pump connected to the low and high pressure outlet until 10 Pa is read on the vacuum gauge. Connect the refrigerant gas cylinder or a charge cylinder to the plug on the low pressure line. Operating conditions that are different from the nominal conditions can create values that are very different.
The sealing test or the search for leaks must only be carried out with R407C refrigerant gas, check with a suitable leak detector. In the cooling circuit, it is forbidden to use oxygen or acetylene or other flammable or toxic gases, because they cause explosions or poisoning. In this way, it will be easy to organize the interventions appropriately, making research and prevention of possible machine breakdowns easier.
It is forbidden to REFILL the circuit with a refrigerant gas different from the one specified.
List of controls for the guided
Radiant panels (floor, etc..) Set the parameter StC (index 3 USER menu) to the value 35 °C Fan coils or. Other applications Set the parameter StC (index 3 USER menu) to the value of 55 °C. 2) Is the external panel accessory installed (PR3). Seasonal control enabled from PR3. ON/OFF control enabled from PR3. 3) Is DHW production provided.
Presumed Set the ASA parameter (index A INSTALLER MENU) with the value (1). 4) Is a 3-way diverter valve provided in the DHW production circuit. This parameter provides the ID of the digital terminal (marked on the PCB with TRA code) to which the room thermostat used to disable compressors and integrative resistors must be connected. For further information on the operations that can be performed with user and installer parameters, refer to the unit's user manual.

NOTE The lower side panel has two identical water IN/OUT (closed by polyethylene caps) and 5 holes for electrical connections. The cable gland can be eyed according to customer's choice which are used for electrical connection and the cables can also be threaded. For a more secure and hermetic connection, preferably remove the cable glands and replace them with suitable cable glands (user responsibility).
NOTE The COVE is delivered separate from the machine body and installation is the responsibility of the installer, or whoever is in charge.
