Fagor CB-30 ECO Instruction Manual page 23

The water heater should be permanently switched on as the control system will ensure that it only operates as required to
maintain the selected temperature and any insignificant heat losses are guaranteed by the polyurethane foam heat
insulation.
In the event of a power failure the water heater stores the settings prior to the power cut and therefore it is not necessary
to press the Start-Stop button (1) again for the water heater to operate.
How to empty the unit. The heater should be fully drained if left unused for extended periods or if subject to freezing
hazards where installed. This can be done by means of the safety valve.
Always remember to:
– Cut-off the power supply.
– Shut-off the input cock.
– Open the hot water tap..
FEATURES
ANTI LEGIONELLA (AL) SYSTEM
This is a preventive system activated by default at the factory to prevent the spread of bacteria such as legionella.
When the water temperature falls below 70 °C for 30 days, the water heater runs a heating cycle until a temperature of 70
°C is reached regardless of the selected temperature setting.
This preventive system can be switched on or off by the user in accordance with that shown in the following table:

POWER MODE (Square water heaters)
The water heater can be configured to operate with one or two resistors or a combination of both options. The user can
select one of the following modes:
• Mono power mode (P1): When heating is required, the water heater activates one of the two resistors alternately,
thereby increasing the service life of the components.
• Dual power mode (P2): When heating is required, the water heater activates both resistors at the same time, thereby
providing a rapid response to reach maximum power.
• Automatic mode (Au): This mode combines the advantages of the above modes: a longer service life at maximum
power. When the water heater detects a significant consumption of hot water, it immediately activates the maximum
power by using all the resistors for the heating. When the consumption is low or if the water temperature is slightly lower
than the setting temperature, the water heater activates each of the two resistors alternately.
The user can select the required mode by following the steps given in the table below:
