VICTRIX 75 - Saint-Roch

IEThe connections of the M and O Bus terminals are used formanaging boilers in cascade.The X40 jumper must be eliminated when connecting the room thermostat orthe cascade adjuster. For safety reasons the circuit board has a non-replaceablefuse in series with the gas valve electric power supply.3.3 MACHINE FUNCTIONING PARAMETERSThe following table gives the boiler adjustment parameters with factorysettings. To modify the parameters reserved for the technician, it is necessaryto enter an access code, which can be supplied on request.To enter the code:- press the MODE and STEP keys at the same time for 2 seconds; the displaywill show the wording CODE and subsequently a random number on thelast two digits;- change the value by operating the + or - keys until reaching the correctcode (54);- press the STORE key to confirm..Possible settings for Technician and UserParameter Description Lower limit value Upper limit value Factory value1 Domestic hot water set value 20 °C 70 °C 20 °C0 = excluded2 Domestic water functioning mode1 = active2 = excluded + continuous pump03 = active + continuous pump3 Heating functioning mode0 = excluded1 = active2 = excluded + continuous pump13 = active + continuous pump4 Heating delivery maximum temperature 20 °C 85 °C 85 °CValue set by technicianPossible settings only by Technician (entering access code)10 Heating delivery minimum temperature 15 °C 60 °C 20 °C11 External lower temperature limit -30 °C 10 °C -5 °C12 External upper temperature limit 15 °C 25 °C 20 °C13 Anti-freeze temperature -30 °C 10 °C 5°C14 External probe reading connection -5 °C 5 °C 015 Second heating circuit maximum temperature NOT ACTIVE16 Second heating circuit minimum temperature NOT ACTIVE17 Second heating circuit hysterisis NOT ACTIVE18 Minimum set point temperature for the temperature19 Booster time20Compensation of external Temperature with roomTemperature0 = Off1 °C 60 °C0 = no booster1 minute 30 minutes0 °C 80 °C 021 Temperature increase with respect to domestic water 0 30 °C 15 °C22 Max. fan rpm in heating (in hundreds) 15 6023 Max. fan rpm in heating (in units) 0 99 024 Max number of fan rpm. in domestic (in hundreds) 15 382526Max number of fan rpm. in domestic water mode (inunits)Min number of fan rpm. in heating mode (in hundreds)0 99 012 6027 Min number of fan rpm. in heating mode (in units) 0 99 028 Fan speed in switch-on phase (in hundreds) 21 25 2329 Fan speed during stabilisation time (in hundreds) 12 38 1730 Stabilisation time 0 900 5431 Heating ascent ramp 0 15 032 Pump post-circulation time at end of heating cycle0 = 10 seconds1 minute 99 minutes33 Pump post-circulation time at end of domestic cycle 0 seconds 300 seconds 6034 Modulation hysteresis in heating ON 0 °C 20 °C 035 Modulation hysteresis in heating ON 0 °C 10 °C 536 Modulation hysteresis in domestic ON -5 °C 30 °C 037 Modulation hysteresis in domestic OFF 0 °C 30 °C 538 Hysteresis detection in domestic ON 0 °C 30 °C 539 Hysteresis detection in domestic OFF -5 °C 30 °C 000Methane = 55GPL = 55Methane = 38GPL = 38Methane = 15GPL = 16398
