The chronothermostat (configuration page) colourful time-lines shows: the blue time-line indicating normal operation, the green
time-line indicating the economical operation, the red time-line indicating the time in which the legionella cycle is programmed
(thus the machine in that condition may be active even if the scheduler is set to Off).
4.7.4.2 WEEKLY PROGRAM SANITARY WATER PRODUCTION
In a similar way to what is reported for the settings on the chronothermostat of chillers and fan coils, you can define when to enable
the production of sanitary hot water (by setting the individual days of the week, with a minimum step of 15 minutes). The settings
that you can do are:
• Normal: Enable function;
•
Off: Disabled function.
To set the programming, go to " Programs " -> " Sanitary ” (the word " Sanitary " appears only if you have enabled the sanitary mode:
System Main -> Configuration -> Service menu -> Parameters -> Chiller -> Chiller name -> H10: Sanitary presence = 1 ).
The procedure for configuring the programmable chronothermostat is therefore similar to those described above, with the only
difference that the choice of the operation is only between " Normal " and " Off " (see figure below).
Figure 26. Chronothermostat, “Sanitary” page.
In the period when the function is active, the machines enabled to produce sanitary water are placed in the seasonal operation of
the plant scheduled by the plant scheduler with the addition of the sanitary mode, that is, respectively:
• sanitary
• sanitary
•
Only sanitary
4.7.4.3 ZONES AND FANCOILS WEEKLY PROGRAM
In a similar way to the scheduling of the chillers, it is possible to set the “weekly program” of each individual zone independently of
the summer and winter seasons, with a resolution of 15 minutes.
The possible settings are:
• Zone in off mode;
• Zone in normal operation (normal room set-point temperature);
• Zone in economic operation (economic room set-point temperature
Therefore entering the "Summer Zone" or "Winter Zone" the list of all the configured zones is displayed. At this point it is necessary
to select the zone that you wish to set; the chronothermostat configuration procedure is then the same as that already reported for
the chillers. In fact, the graphical appearance and functionalities of the page are identical to those already described.
4.7.4.4 LEGIONELLA DISINFECTION WEEKLY PROGRAM FUNCTION
If the sanitary function is enabled (from system main page -> Configuration -> Service menu -> Parameters -> Chiller -> Chiller name -
> H10: Sanitary presence = 1 ), you can program the hours of the individual days of the week for activating the cycle of anti-
legionella disinfection.
You select only the starting time (with 15 minutes steps), since the duration of the cycle is defined by a parameter with maintainer
access rights (System main page --> Configuration -> Service menu -> Parameters -> Keyboard -> Par 31/65: Legionella disinfection
enable time ) .
To carry out the programming you must enter into “ Programs ” -> “Legionella disinfection”; the procedure is simple because you
have to select only the starting day and hour for the cycle (see the below figure).
