5. Operating Instructions
The Ferroli Pegaso Eco water heater is designed for user-friendly operation with intuitive controls.
Controls:
- Ergonomic Knobs: Use the rotary knobs on the front panel to adjust the power output and the desired hot water temperature.
- Display: The interface display provides necessary information regarding the appliance's operation and battery charge status.
Functions:
- ECO Function: Activate the ECO function to set the hot water temperature to an ideal 42°C, while simultaneously reducing the maximum power output to 80%. This optimizes comfort and energy savings. Both temperature and power reduction parameters can be adjusted according to user preferences.
- SUN EASY Integration: When integrated with a solar thermal system, the water heater continuously monitors the temperature of the water from the solar circuit. The burner will only activate if the solar-heated water is not hot enough to reach the desired setpoint temperature. This ensures maximum utilization of solar energy, leading to significant savings even in colder seasons.
To operate, ensure the gas supply is open and the appliance has sufficient battery power. Adjust the desired water temperature using the control knobs. The water heater will automatically ignite when hot water is demanded.

- Professional Inspection: An authorized service technician should check all components, including the heat exchanger, gas connections, and safety devices, at least once a year.
7. Troubleshooting
This section provides solutions to common issues. For problems not listed here or if issues persist, contact a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water / Appliance does not ignite | No gas supply, low water pressure, dead batteries, flue obstruction. | Check gas valve, ensure sufficient water flow (above 11 liters/minute for ignition), replace batteries, check flue for blockages. |
| Water not hot enough | Temperature setting too low, ECO function active, insufficient gas pressure, scale buildup. | Increase temperature setting, adjust ECO function parameters, check gas supply, consider professional descaling. |
| Unusual noises | Air in the system, scale buildup, loose components. | Bleed air from water lines, professional descaling, contact technician for inspection. |
