Install Instructions

Operating status

Depending on the times and the programs that have been set, the controller may be in one of

the following operating modes.:

• Adjustment;

• Disinfection;

• Flushing;

• Thermal shock (this function has #1 priority over other modes)

In the event of trouble due to the LEGIOMIX

or the system, the device manages and reports the

alarm and, depending on the situation, may maintain operation or not. Accordingly, a distinction

is made between the following:

• Active with alarm

• Inactive with alarm

The LEGIOMIX

is equipped with a rechargeable battery that keeps the clock working and

maintains selected programmed settings during loss of power. In the event of blackout, to

ensure the longest battery life, the controller assumes the status:

• Inactive on Low Power

Adjustment (modulation)- default mode

LEGIOMIX measures the temperature of the mixed water at the valve outlet with temperature

sensor and adjusts (modulates) the mixing valve position to maintain the desired set temperature.

Disinfection

LEGIOMIX runs the disinfection phase, which consists of raising the water temperature to a pre-

set value for a specific time duration, by operating the mixing valve as required.

Using the menu, set the days of the week for the disinfection phase to run.

At the end of disinfection, statistical data relating to the just concluded disinfection are logged.

This mode begins and ends automatically at a start time (Time ON) and end time (Time OFF)

that can be selected by the user in SETTINGS.

Safety measures must be in place before engaging disinfection mode. Anti-scald

protection devices, certied to ASSE 1016 or ASSE 1070, at all downstream xtures,
