Air conditioning modes
By pressing the
MODE
key consecutively, the following air
conditioning modes can be selected.
Off
In this mode the air conditioning system is off. The screen
displays the word OFF, the room temperature, the day of the
week and the time. If the fan is active, this will also be shown.

°C
Entering this mode gives access to the configuration values
that could have been changed temporarily, the set points and
fan status.
Cool
This mode activates cooling operation only. The screen dis-
plays the word COOL (air conditioning mode), room tempera-
ture, the
icon (flashing if there really is a demand, and
static if not), room occupation status (Day, Night or Unoccu-
pied), fan status, day of the week and time.
A demand is generated when the room temperature is above
the programmed set point. Set point is understood as the tem-
perature we want in the room. How to program and change set
points will be described further below.
Heat
This mode activates heating operation only. The screen dis-
plays the word HEAT (air conditioning mode), room tempera-
ture, the
icon (sides flashing if there really is a demand,
and no sides if not), room occupation status (Day, Night or
Unoccupied), fan status, day of the week and time.

A demand is generated when the room temperature is below
the programmed set point. Set point is understood as the tem-
perature we want in the room.
Auto
This mode activates heating as well as cooling operations.
The screen displays room temperature, the word AUTO (air
conditioning mode), the
and
icons (flashing if there is
a demand), room occupation status (Day, Night or Unoccu-
pied), fan status, day of the week and time.
A demand is generated when the room temperature is above
the cooling set point or below the heating set point. In auto-
matic mode, room temperature is kept at a value between
these two programmed set points.
Programmed
The programmed mode involves the previously described AUTO
mode and includes the time schedule profile. The

conditioning mode appears on the display.

The time schedule profile defines, for each hour of the day (in
15-minute intervals), whether the set points that control the
thermostat are Day (comfort) or Night (economy).
Exiting this mode recovers the temporarily changed values,
set points and fan status.
If pin 2 of the micro-switch is set to OFF, this option does not
appear (see Configuration of micro-switches).
