Flow temperature
Disinfection is considered successful when:
Disinfection code: d1
Flow temperature = Maximum available temperature
Minimum disinfection time = minimum disinfection time diS °C = 30’
Disinfection is considered successful when the temperature of the probe enabled remains above the minimum disinfection temperature (diS
°C) for a minimum set time (tmin diS) within a maximum time limit (tHi diS).
Example with ECO function disabled.

Disinfection programs:
Different programs can be set, chosen according to the type of system and its management:
Disinfection type with flow probe T1 enabled
Disinfection Code
Description
d1
Disinfection performed at maximum available flow temperature, limited to the system maximum temperature set (T1
Hi). Disinfection check performed on probe T1.
d2
Disinfection performed at the minimum disinfection temperature (diS °C). Disinfection check performed on probe T1.
Disinfection type with recirculation probe T2 enabled
Disinfection Code
Description
d1
Disinfection performed at maximum available flow temperature, limited to the system maximum temperature set (T1
Hi). Disinfection check performed on probe T2.
d2 (default)
Disinfection at the flow temperature calculated according to the return temperature T2. Disinfection check performed
on probe T2.
ECO FUNCTION
The ECO function does not take into account the minimum disinfection time, but calculates it based on the actual temperatures according to the
following table. If the temperature drops below 60°C, counting starts from the beginning.

The ECO function is applicable to all disinfection modes, before using this mode, it is necessary to check that the proposed disinfection times are
in accordance with the regulations in force in the country of installation.
