Operating status
Depending on the times and the programs that have been set, the appliance may be in one of the following operating modes:
•
Adjustment;
• Disinfection;
• Flushing;
• Thermal shock (this function has priority over the previous ones).
In the event of a trouble due to the appliance or the system, the device manages and reports the alarm and, depending on the situation, may maintain
operation or not. In this context, a distinction is made between the following statuses:
• Active with alarm
• Inactive with alarm
The appliance is equipped with a rechargeable battery that keeps the clock working in the event of electric supply failure.
In the event of a blackout, in order to ensure the longest possible operating time for the battery, the appliance assumes the status:
• Inactive on Low Power.
Adjustment
In this mode the appliance continually checks the temperature detected by the flow probe and adjusts the mixing valve accordingly so that the flow
temperature is maintained at the programmed set point.
Disinfection
In this mode the appliance carries out a 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.
It is possible, using the menu, to set the days of the week on which disinfection must be carried out.
At the end of disinfection, the statistical data relating to the disinfection that has just been concluded 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.
If, within the time span (Time OFF - Time ON), the actual disinfection time reached tDIS is greater than the set tMIN, the disinfection is concluded with a
positive outcome. It automatically exits this status and returns to adjustment.
If it is not possible to reach a sufficient time tDIS, the disinfection phase anyhow ends at Time OFF.
Example:
Time ON: 2:00
Time OFF: 3:00
tMIN: 30 min
Program: 1A
Tdisinfection: 60°C
If, in the time span of 1 hour, the temperature remains over 60°C for at least 30 minutes, disinfection is successful
and the regulator returns to adjustment mode. Otherwise, disinfection anyhow ends at 3:00.
