Thermostats have the possibility of 4-zone 7-day programming which allows you to set the temperature in 4 different time zones for each day of the week separately. In addition, thermostats have the option of automatic activation and deactivation at a specified hour. The ability to choose one of the 3 work modes allows you to use heating, cooling or ventilation systems.
