Modena HE 18s, 25s & 32s - Ferroli

MODENA S HE1. Instructions1.1 IntroductionThank you for choosing the MODENA S HE, a FERROLI wall-mounted boiler the latest generation appliance, featuringadvanced design and cutting-edge technology.MODENA S HE is a high-efficiency condensing pre-mix appliance for central heating and hot water production, runningon natural gas or LPG, generating extremely low emissions.The boiler is constructed with a stainless steel heat exchanger providing effective condensation of the water vapour containedin the flue gases, permitting extremely high efficiency.Inside the boiler there is a premix burner with an integral fan, with a large stainless steel surface.The boiler is totally room sealed from the installation room: the air needed for combustion is drawn from outside. Theboiler also includes a modulating speed fan, modulating gas valve, pump, expansion vessel, safety valve, flow sensor,safety and control double temperature sensors, a safety thermostat and a low water pressure switch.Thanks to the microprocessor control and adjustment system with advanced self-diagnosis, unit operation is for themost part automatic. The power for heating is automatically governed by the control system.The display continuously provides information on the unit’s operating status and it is easily possible to obtain additionalinformation on the sensor temperatures, set-points, etc. or configure them. Any operating problems associated with theboiler or system is immediately signalled by the display and, if possible, corrected automatically.1.2 Control panel12157178511143 4 13 16 6fig. 1 - Control panelKey1 = Domestic Hot Water temperature setpoint decreasingpush button2 = Domestic Hot Water temperature setpoint increasingpush button3 = Central Heating water temperature setpoint decreasingpush button4 = Central Heating water temperature setpoint increasingpush button5 = Display LCD6 = Reset7 = On-Off push button8 = Domestic Hot Water symbol11 = Multi-function indication (Flashing during heatexchanger protection)13 = Central Heating mode operation14 = Central Heating symbol15 = Burner on and actual load indication (Flashingduring flame current supervision)16 = Service tool connector17 = Water gauge4 ENcod. 3541C364 - Rev. 00 - 12/2012
