up the system to activate at 06:30. To do this, programme the desired temperature for

06:00 and set a 30-minute delay; the device will activate the system at 6:30. The set

delay is shown on the display during the hour in which the delay has been scheduled.

Note. The delay time can be programmed for multiple hours in the same day and for

multiple days of the week.

reappears on the screen to conﬁ rm that the temperature ranges have been programmed.

The device exits the procedure 10 seconds after the last action and the data entered up

to that moment are accepted as valid.

Note. The value that can be assigned to each temperature range is limited by the values

of the range immediately above and below it.

If, for example, range T3 is set at 20°C and range T1 is set at 16°C, the value of range

T2 can vary between 16.1°C and 19.9°C; if T2 is set at 21°C, T3 is automatically

increased to 21.1°C.

Press button .

The icon appears to conﬁ rm

that the programme has been

activated.

Use of the all-purpose program

The device includes an all-purpose programme (to be used, for example, during holidays

or on midweek public holidays) that can be activated at any time of the current day and

remain active until 24:00. It can also be pre-requested for use on any day of the week.

The all-purpose programme is factory set to the same proﬁ le as the one set for Sundays

, but it can be customised.

To activate this programme for the current day:

Set the AUTOMATIC operating mode.

Press button P to confirm the

temperature value shown on the

display and move on to the next

temperature level .

Continue as described to set all

the temperature ranges as you

want them.

Use buttons to set the

desired correction value.

Note. The setting is saved in the

device’s permanent memory.

Enabling/disabling automatic advance

This function (only active in heating mode) enables the device to automatically adapt

the system start-up time, in order to have the desired temperature at the time set. The

advance is calculated according to the di erence between the temperature detected

and the one set. It is possible to set an advance of up to three hours with respect to the

time set for the temperature to be reached.

Operating example

If the device is programmed to 20°C at 7.00 a.m. and the automatic advance is not

active, at 7.00 a.m. the system will come on, without guaranteeing 20°C at 7.00 a.m.

If automatic advance is on, the programmable thermostat will switch on the system

earlier so as to try to reach 20°C at 7.00 a.m. Through the auto-recognition mechanism,

the programmable thermostat stores the thermal parameters of the room in order to be

more accurate on subsequent days in reaching the temperature set.

Activate the MANUAL operating

mode.

Press button P until shows on
