If the value of this parameter remains at 00 the function is not activated. 2. 4. 5 Circulation pump MAX from 75 to 100 100 speed GENUS PREMIUM EVO HP 85/100/115/150 with optional pump kit - modulating 2. 4. 6 Circulation pump MIN from 40 to 100 speed GENUS PREMIUM EVO HP 85/100/115/150 with optional pump kit - modulating 2. 4. 7 Central Heating Pressure detection device 0 = Temperature Probes only 1 = Pressure switch 2 = Pressure sensor ONLY FOR SERVICE - To be used only in substitution P.C.B. 2. 4. 9 External temperatura from -3 to +3 0 correction Only active with external sensor connected 2. 5 DOMESTIC HOT WATER Activated with the boiler connected to a tank by an NTC sensor 2. 5. 0 COMFORT Function 0 = Disabled 0 1 = Time Based (30 minute) 2 = Always active This function keeps the external tank warm during the periods in which the boiler is inactive. When the function is enabled the text COMFORT appears on the display. Note: this function can be activated or deactivated by the user as well - consult the User’s Manual. 2. 5. 1 Comfort Anti-cycling Time from 0 to 120 0 minutes 2. 5. 2 Hot water flow delay from 5 to 200 5 (0.5 to 20 seconds) Anti "water hammering" 2. 5. 3 D.H.W. switch logic 0 = Anti-scale (stop at > 67°C) 1 = At 4°C over setpoint 0 2. 5. 4 Post-circulation and postventilation after domestic hot water is drawn 0 = OFF 1 = ON OFF = 3 minutes post-circulation and post-ventilation after domestic hot water draw-off if the boiler temperature measured requires it. ON = always on for 3 minutes post-circulation and postventilation after domestic hot water draw-off. 2. 5. 5 Delay start in Central Heating after D.H.W. request from 0 to 30 (minutes) 2 1 0 2. 5. 7 Anti-legionella Function 0 = OFF 0 1 = ON Activated with the boiler connected to a tank by an NTC sensor This function prevents the formation of Legionnaire’s disease bacteria which may develop in the piping and indirect cylinders at temperatures between 20°C and 40°C. If activated, whenever the indirect cylinder temperature stays below 59°C for over 100 hours, the boiler heats the water in the indirect cylinder until it reaches 65°C for 30 minutes. 2. 5. 8 Antilegionella frequency from 24 to 720 100 (hours) 2. 5. 9 Temperatura obbiettivo from 60 to 70 (°C) 66 antilegionella 2. 6 BOILER MANUAL SETTINGS 2. 6. 0 Manual mode activation 0 = OFF 0 1 = ON 2. 6. 1 Boiler pump control 0 = OFF 0 1 = ON 2. 6. 2 Fan control 0 = OFF 0 1 = ON 2. 6. 3 Diverter valve control 0 = OFF 0 1 = ON 2. 7 TEST & UTILITIES 2. 7. 0 Test mode 0 = OFF 0 1 = ON Turn the encoder to select ON and press OK. The boiler is forced to the maximum heating power. Turning the encoder allows for selecting the D.H.W. maximum or minimum power operating mode It is possible to activate the Cleaning Function (Chimney active) by pressing the Reset button for 10 seconds. 2. 7. 1 Air purge Function 0 = OFF 1 = ON Turn the encoder to select ON and press OK. The Deaeration Cycle can be activated by pressing the ESC button for 5 seconds. 2. 8 RESET MENU’ 2 2. 8. 0 Reset factory settings Reset OK = yes ESC = no To reset all default parameter settings, press the OK button 4 ZONE 1 PARAMETER 4. 0 ZONE 1 TEMPERATURE SETTING 4. 0. 2 Fix temperature central from 35 to 85 (°C) 70 heating (high temperature) from 20 to 45 (°C) 25 (low temperature) To set only with Fixed Flow Temperaure of Thermoregulation (see 421) 4. 2 ZONE 1 SETTING 4. 2. 0 Zone 1 Temperature range 0 = from 20 to 45°C (low temperature) 1 = from 35 to 85°C (high temperature) 34

The type of curve should be selected in correspondence with the projected temperature of the system and the nature of the dispersions present in the structure. For high-temperature systems, one of the curves depicted below may be chosen. 4. 2. 3 Parallel curve shift Zone 1 Offset Auto Function active from - 14 to + 14 (°C) 0 (high temperature) from - 7 to + 7 (°C) 0 (low temperature) To adapt the heating curve to the system requirements, shift the curve in parallel so that the calculated flow temperature is modified, in addition to the room temperature. By accessing the parameter and turning the encoder, it is possible to shift the curve in a parallel direction. The shifting value can be read on the display: from -14 to +14 for high-temperature devices, or from -7 to 7 for low-temperature devices. Each step corresponds to a 1°C increase/decrease In the flow temperature with respect to the set-point value. 4. 2. 4 Room sensor Influence from 0 to 20 20 to calculate the setpoint temperature - Thermoregulation enabled- If setted = 0 the room temperature doesn’t influence the calculation of the set-point. If setted = 20, the room temperature has the maximun influence to calculate the set-point - only active when the BUS device is connected 4. 2. 5 Maximum Central Heating from 35 to 85 °C 82 Temperature Zone 1 (Param. 420 = 1) from 20 to 45 °C 45 (Param. 420 = 0) 4. 2. 6 Minimum Central Heating from 35 to 85 °C 40 Temperature Zone 1 (Param. 420 = 1) from 20 to 45 °C 25 (Param. 420 = 0) 4. 3 DIAGNOSTICS 4. 3. 4 Zone 1 heat request 0 = OFF 1 = ON 5 ZONE 2 PARAMETER 5. 0 ZONE 2 TEMPERATURE SETTING 5. 0. 2 Fix temperature central from 35 to 85 (°C) 70 heating (high temperature) from 20 to 45 (°C) 25 (low temperature) To set only with Fixed Flow Temperaure of Thermoregulation (see 521) 5. 2 ZONE 2 SETTING 5. 2. 0 Zone 1 Temperature range 0 = from 20 to 45°C (low temperature) 1 = from 35 to 85°C (high temperature) 1 5. 2. 1 Select Type of Thermoregulation To enabled thermoregulation press Auto button.
