4DEVICE DESCRIPTION
information to users pursuant to art. 14 of the directive
2012/19 / EU of the european parliament and of the council
of 4 july 2012 on waste electrical and electronic equipment (WEEE)
If the crossed-out bin symbol appears on the equipment or packaging,
this means the product must not be included with other general waste
at the end of its working life.
The user must take the worn product to a sorted waste center,
or return it to the retailer when purchasing a new one.
Products for disposal can be consigned free of charge (without any new purchase obligation)
to retailers with a sales area of at least 400 m2, if they measure less than 25 cm.
An efficient sorted waste collection for the environmentally friendly disposal of the used device, or its
subsequent recycling, helps avoid the potential negative effects on the environment and people’s health,
and encourages the re-use and/or recycling of the construction materials.

of the delay, the temperature value assigned to the previous hour.
For example, if the program includes:
T2 from 12 to 13 and T3 from 13 to 14 pm with 30 minutes delay
the chronothermostat adjusts the temperature based on the value of
T2 from 12 to 13.30 and T3 from 13.30 to 14.00
It is possible to set delays of 15, 30, 45 minutes, independent for every hour of the day.
