5
AIR RETURN SENSOR
: connecting a temperature probe in the air return point (usually under the fan coil), the
thermostat manages temperature control with the temperature read by this probe.
Note
: by selecting option 4 SUMMER/WINTER mode cannot be changed manually.
P12 Temperature sensor on external temperature sensor input
1
NOT CONNECTED:
the input is not used.
2
ON/OFF:
by connecting a normally open or normally closed contact, according to what is selected in item
P14
, the
thermostat goes into off mode or on mode.

P14
, the thermostat goes into comfort mode or economy mode.
5
REDUCTION:
connecting a normally open or normally closed contact, according to what is selected in item
P14
,
there is a reduction of 3.0°C in the setpoint temperature value in winter mode, or an increase of 3.0°C in the setpoint
temperature value in summer mode.
6
AIR RETURN SENSOR
: connecting a temperature probe in the air return point (usually under the fan coil), the
thermostat manages temperature control with the temperature read by this probe.
7
MINIMUM SENSOR WINTER ONLY
: connecting a temperature probe to the supply pipe, the thermostat will not start
the fan until the temperature of the water has reached the value set in item
P33
.
8
SUMMER/WINTER MINIMUM SENSOR
: connecting a temperature probe to the supply pipe, the thermostat will not
start the fan until the temperature of the water has reached the value set in item
P33
(winter mode) or
P34
(summer
mode).
9
CHANGE-OVER SENSOR
: connecting a temperature probe to the supply pipe, the thermostat automatically manages
the Winter/Summer change-over with the temperatures programmed in items

temperature value in summer mode.
P15 Room temperature correction
P16 Temperature correction on external sensor
P17 Temperature correction on remote sensor
These parameters are used to correct the room temperature value read, since in certain installations, the room
temperature read may be unsatisfactory due to the position of the probe (internal or return).
P18 Display mode

Troom:
the display usually shows the room temperature.
2
Set-point
: the display always shows the current temperature set point value.
P19 OFF display mode
1 The display shows 'OFF'.
2 The display shows the room temperature or set-point according to what is selected under
P19
.
