Periods with Lowering of Temperature

With DEVIreg™ 550 you have the possibility of either setting
the thermostat to keep a constant temperature, or let the
thermostat automatically switch between periods with a
lower temperature (also called economy temperature) and
periods with comfort temperature.
By default, the thermostat is set to the following comfort
periods:
▪ Monday - Friday: 6:00 - 8:00 and 16:00 - 22:30.
▪ Saturday - Sunday: 6:00 - 22:30.
In order to automatically switch between comfort tempera-
ture and economy temperature (e.g. when going to bed or
to work), the timer function is used.
The temperature will be lowered by a certain number of
degrees compared to the comfort temperature. By default
this number is preset to -5°C.
If the adaptive function is active (this is normally the case),
you only need to select the time at which you require com-
fort and economy temperatures. The thermostat will then
calculate when the heating should start in order to reach
the desired temperature at the specified time.
