When this temperature value is set, the boiler automatically switches from summer to winter mode when the outdoor sensor detects an average temperature value, calculated over 24 hours, higher than the set point. 20 8...30 P532 HC1 circuit heating curve gradient (parameter for the installation engineer). 15 1 ... 40 P533 HC2 circuit heating curve gradient (parameter for the installation engineer). 15 1 ... 40 P534 HC1 circuit parallel shift (parameter for the installation engineer). 0 -31 ... 31 K P535 HC2 circuit parallel shift (parameter for the installation engineer). 0 -31 ... 31 K 3-8 - Fault warnings and resetting the boiler If a fault occurs, a flashing warning code appears on the display. The fault warnings appear on the main display (figure 1 a) together with the symbol (Figure 4). To reset, press the reset button for at least two seconds. 020503_0500 Figure 4 8
Fault warnings appear on the secondary display (figure 1 b) alternating with the time, both of them flashing (figure 4.1). It is not possible to reset malfunction warnings which appear on the secondary display as the cause of the alarm has first to be removed. 020503_0600 Figure 4.1 3.9 Fault warnings table Fault code 10 20 50 110 Fault description outdoor temperature probe sensor failure ntc output sensor failure domestic hot water ntc sensor failure safety or flue gas thermostat tripped action required call the authorised service centre. call the authorised service centre call the authorised service centre press the reset key (for about 2 seconds: if this device is triggered repeatedly, call the authorised service centre) 132 133 135 floor thermostat tripped no gas fan electricity supply failure call the authorised service centre press the reset key (for about 2 seconds); if the fault persists, call the authorised service centre) call the authorised service centre 151 boiler circuit board error switch off the electricity supply to the boiler for 10 seconds; if the fault persists, call the authorised service centre) 153 the reset key has been pressed inappropriately press the key again (about 2 seconds) 154 internal error on boiler circuit module Press and hold reset button (2 seconds approx.) then press again when warning E153 appears 160 fan speed threshold not reached call the authorised service centre. 164 no hydraulic differential pressure switch enabling signal check that the system is at the rated pressure. (refer to the section on filling the system). if the fault persists, call the authorised service centre. 183 saving parameters If the warning is displayed for more than 3 seconds, press and hold the reset button (2 seconds approx.) then press again when the warning E153 appears All the faults are displayed in order of importance; if several faults occur simultaneously, the first to be displayed is the one with highest priority. After the cause of the first fault has been removed, the second one will be displayed, and so on. If any given fault occurs frequently, contact the authorised Service Centre. 9
