In order to avoid all risks of accident during the installation, commissioning and adjustment operations, it is imperative to take into consideration the specificities of material, such as : ­ refrigerant circuit under pressure ­ presence of refrigerant fluid ­ presence of voltage ­ siting Only qualified and experienced personnel should work on such equipment. IMPORTANT : before working on the unit, make sure that the electrical supply is cut. [. . . ] " commissioning "), the position of the ambient box thumbwheel and the outside temperature. In cooling mode, the unit starts as soon as the ambient temperature goes above P09. The unit regulates with the fixed setting on the P36 water return. The ambient box tumbwheel and the outside temperature have no influence on this mode. Note : the cooling mode permits creating a temperature difference of 3 to 5°C between the indoor and outdoor temperature. To install the manual reset thermostat on the unit, you must : 1 - dismount the unit roofing and withdraw the electrical panel door. 2 - fix the 63°C manual reset thermostat on the electrical panel (position 1, next to the 78°C thermostat of the electrical auxiliary devices) For this type of installation, we recommend using the Climbox 2 programme and the cooling/heating floor kit, both of which are available in the catalogue. The cooling/heating floor kit includes : ­ 1 ambient box with ambient temperature adjustment (+/- 3°C) thumbwheel. 4 - fix the thermostat capillary on the water departure copper tube with 2 plastic clips, then cover with the insulation also held in place with 2 plastic clips. Connection recommendations : All the entries must be voltage free and of good quality. ATTENTION : do not connect a phase or a neutral on terminals 7 to 12 of terminal box J2. Control of unit with the all or nothing entries of the MRS 5. Plan a shrouded cable connection whose passage will be at least 30 cm distant from all lines succeptible of generating parasites, the shrouding will be connected to the mass at both ends. Be used with a push button type contact. ­ Common If the heating and cooling entries are supplied simultaneously, the unit goes into stop mode. If the frost-free entry is supplied simultaneously with the heating and/or cooling, the unit goes into frost-free mode If there are several shrouded cables, each shrouding will be connected separately (if a risk of parasite still exists, plan the relay of several entries). Distance superior to 30 meters : Plan relaying the various entries, 1 relay per entry mounted in the vicinity of the electronic card (cables section : 0. Entries : heating/cooling operation ­ building frost free : return water temperature maintained at 30°C ­ electrical auxiliary devices shedding/repowering : closed = shedding ­ remote assistance resetting : in case of level 1 fault, the contact closing permits relaunching the electrical auxiliary devices for 48h heating (while waiting for fault repair). This entry must It offers a fault exit NO/NF (terminal box J2 of the MCAD5) and an automaticity control (terminal box J2 of the MCAD5). Automaticity control : you can connect a potential free contact (ex : clock. ;) between 1 and 2 on the terminal box J2 : closed contact : operation of the unit authorised open contact : unit is stopped. ATTENTION : do not connect a phase or a neutral on terminals 1 and 2 of terminal box J2. [. . . ] It can help to ensure the heating while waiting for repair on the refrigerant circuit (refrigerant leak, etc. ­ that the discharge is heating (reading of parameter P55), ­ that the absorbed amperage is normal (see table " electrical characteristics "), ­ the operation of all the safety devices (see the table " regulation and safety device "). Thermodynamic phenomena related to the installation, which can arise when starting Regulation as a function of the outside temperature : P03 = 1 Adjustment of the water law : P36 = 20°C and P27 = 20°C P28 = Min. Basic outside temperature of the area P29 = water return temperature used in the calculation of the house thermal losses at the min. [. . . ]
