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, certified to ASSE 1016 or ASSE 1070, at all downstream fixtures,
