Operating modes

By successively pressing the mode key the emitter is changed from one mode to another.
To identify the mode a screen is initially displayed for 2 seconds.
COMFORT:
The first mode of operation that appears when the emitter is connected for the
first time, and changed from Standby to Operational, is "comfort".
In this mode, the desired room temperature is selected by - and + keys, between
12 °C and 30 °C in steps of 0.5 °C (if the keys are held, the temperature changes
faster). When the temperature reaches either the maximum or minimum value it
will stop.
Typical comfort temperature is 20-21 °C. The comfort mode is normally used dur-
ing the hours the room is occupied.
ECONOMY:
The next mode that appears is "economy", which automatically sets a tempera-
ture between 0.5 °C and 4.5 °C less than the previously selected comfort temper-
ature (the difference can be directly set by the user with the - and + keys). When
the comfort temperature is raised or lowered, the ECO temperature automatical-
ly rises or falls by the set amount.
While the comfort temperature can be set from 12 °C to 30 °C, the ECO tempera-
ture is from 7.5 °C to 29.5 °C, but always between 0.5 °C and 4.5 °C below the
comfort temperature.
Economy mode is used for short absence periods to prevent the temperature
from falling excessively.
ANTI-FROST:
PROGRAM:
42
In this mode, the temperature setting is 7 °C and is factory set.
Anti-frost is usually used as an off set point and for long periods
of absence when you want to avoid freezing.
In Program mode, the emitter automatically switches between the 3 mode
temperatures according to the daily and weekly program set by the user.
The bar chart is displayed permanently and displays the 24-hour program di-
vided into one-hour intervals. Each one-hour interval can be programmed as
comfort, eco or heating off. The bar showing the current time flashes to indi-
cate to the user what the current set point is.
