Page 9: Typical Use
Typical use Preliminary operations f Firstly, the knob 12 should be on the position 8 . f Make sure, by the gauge 17 that the cold-system temperature is al- service ways within 0.5 and 1.5 Bar (opti- mal: 1÷1.5 Bar). When the pressure drops below 0.5 Bar, the boiler stops working. -

Page 11: Boiler Inactivity
Boiler inactivity The effects of the periods of inactivity can be relevant in particular situations such as in flats used only for some months per year, most of all in cold places. The user will have to decide to put the boiler in the SAFETY SHUT OFF state disconnecting all the sup- plies, or to leave it in stand-by and use the Anti Frost Function. -
Page 12: Ambient Anti-Frost" Function
ATTENTION: the anti-frost protections cannot intervene in the absence of electricity. If you an- ticipate this possibility, we recommend you add a good brand of anti-freeze to the heating sys- tem, following the producer’s instructions. We recommend to ask directly the installer/technician about the type of antifreeze product put in the heating system during installation. -

Adjustment and Maintenance ATTENTION: the operations described below must be carried out only by qualified personnel [authorized by ITALTHERM] . When regulation/measuring is over, remember to tighten pressure tapping point screws and ALWAYS check for gas leaks! Before boiler ignition, verify that pump is not blocked due to its inactivity: unscrew the plug located in the middle of the cap to gain access to the rotor shaft, and turn it manually using a screwdriver or another suitable tool. -

Remote Control Kit This remote control is more than a simple room thermostat . Thanks to this, it is possible to manage the boiler in all its set- tings like DHW and CH temperature adjustment, boiler reset in case of boiler block, and of course it works as a room thermo- stat both in manual and weekly program mode. - Page 40 ITALTHERM Srl Via S.
