This phenomenon is completelynormal and has been designed specifically to stop the screens from overheating.IMPORTANT: the ambient temperature is displayed on the remote screen followed by the letter “A”, while the temperature of the water inthe boiler is followed by the letter “R”. The thermoproduct boiler water temperature probe (l1) must be connected directly to the remotedigital regulator. The probe cable can have a maximum length of 5 metres.IMPORTANT: the digital regulator installed in the All Inclusive UNIVERSAL module must be connected to the remote digital regulator, asshown in Picture 2 at page 24, through a bipolar electric cable (NOT included), with a length that does exceed 100 metres8. WATER CIRCUIT MAINTENANCEWith the system switched off, once a year carry out the following checks:• Check the operation and efficiency of the blowdown and safety valves. If they are defective, contact your authorised installer. IT ISSTRICTLY FORBIDDEN TO REMOVE OR TAMPER WITH THE SAFETY DEVICES.• Make sure that the system has been filled and is pressurised (see the manual for the heating appliance combined with the AllInclusive Module).9. SUMMER SET ASIDEATTENTION: the installation must be kept constantly full of water even in periods in which the use of thermofireplaces is not required.During winter time, inactivity must be faced by adding antifreeze substances.OPEN expansion VESSEL system: check the water level in the expansion tank and remove any air from the system by bleeding theradiators; also check to make sure that the plumbing and electrical accessories (control unit, circulator) are working properly..
