4.13 HOLIDAY MODE

At the function setting page, select “Holiday mode” and set it to “On” or “Off”.
You can use the weekly timer to assign the “Holiday” program to at least one day
of the week. On those days, the unit will work in heating mode, maintaining a 30°C
set-point on delivery water (or 10°C if the check is based on the ambient air). To
enable the implementation of the Holiday Program (if set on the weekly timer), you
must activate this function.
After accessing the “Holiday mode” function, you can choose one of the modes
available by clicking directly on the text that identifies it and then confirming with
the ”OK” key.

Note:

— Before changing the operating mode, the unit must be OFF, otherwise a mes-

sage will warn you to turn the unit off before changing the mode;

— During the use of Holiday mode (as set in the weekly timer), the operating

mode will be automatically set on “Heating” and the On/Off command from the
panel cannot be used;

— None of the functions linked to the timers will be available during Holiday

mode;

— You can use the weekly timer to assign the “Holiday” program to at least one day

of the week. On those days, the unit will work in heating mode, maintaining a
30°C set-point on delivery water (or 10°C if the check is based on the ambient
air). To enable the implementation of the Holiday Program (if set on the weekly
timer), you must activate this function.

— Certain functions are not available in Emergency mode so, if you attempt to

activate them, the system will tell you to disable Emergency mode first;

— If the relative function is activated (paragraph "8.1 Activating/deactivating the

memory (On/off memory) p. 32"), the value of this parameter will be stored in
the memory and automatically reset after any possible voltage failure.

4.14 PRESET MODE

At the function setting page, select “Preset mode” and go to the corresponding set-
ting page.
This function is used to set one to four daily periods, whose commands will then
be executed every day. After accessing the “Preset mode” function, you can press
the key for each period to activate or deactivate an individual period, choose the
operating mode to be used, the temperature set-point for processed water, and the
start and end times of the period itself.

Preset mode

Period 1: Valid

Period 2: Invalid

Period 3: Invalid

Period 4: Invalid

At the time period setting page, each time period can be set to “Valid” or “Invalid”.

Preset mode

Period 1: Valid

Mode: Heat

WOT Heat: 45°C

Start timer: 00:00

End timer: 00:00

Clicking on the "Period" label will open the page with the labels relating to period
activation, the mode to be used during the period, the water delivery temperature
and the start and end times. Click on each of these to set the appropriate value
(each data item may draw up additional windows for selecting or entering the re-
quired values). Lastly, press the top right button to save the data entered.

Note:

— If the compatible Aermec accessory tank for this model (refer to the installation

manual for more information) is not installed and correctly set, the “DHW” func-
tion will not be available;

— If timer programming with the Weekly timer and other settings with Preset

mode have been entered simultaneously, the latter will take priority;

— When the water tank is available, the preset mode can be "Heat", "Cool", or "Hot

Water"; however, when the water tank is unavailable, the preset mode can only
be "Heat" or "Cool".

— Up to four time bands can be set for each day, but their start and end times

must coherent (the beginning of one period must be later than the end of the
previous period);

— If the unit is switched on manually, the period timer programs will not be im-

plemented;

— When "Start timer" is reached, the unit will perform the preset mode. When
