Normal operation
- If pressed once shows the set-point temperature.
- If pressed repeatedly decreases the set-point temperature.
In configuration mode
- If pressed once shows the set parameter.
- If pressed repeatedly changes the selected parameter
(decreases the value).
B Multifunction key '
'
Normal operation
- If pressed once shows the set-point temperature.
- If pressed repeatedly increases the set-point temperature.
In configuration mode
- If pressed once shows the set parameter.
- If pressed repeatedly changes the selected parameter
(increases the value).
C Multifunction key '
'
Normal operation
- Sets the regulation mode: Comfort => Economy.
- If pressed for 10 seconds, accesses to the user parameters.
In configuration mode
- Enter in modification mode of the selected parameter.
- Exits from modification mode of the selected parameter.
D Multifunction key '

DISPLAY INDICATIONS
The meaning of the symbols appearing on the display is given
below:
Temperature regulation in Comfort mode.
Temperature regulation in Economy mode.
Thermostat switched off, OFF mode.
Antifrost mode active, the thermostat regulates to
antifrost
Heating mode, output on.
Cooling mode, output on.
The thermostat is in configuration mode /
The thermostat shows the set-point temperature.
The thermostat shows the room temperature detected by
the internal sensor.
The thermostat shows the room temperature detected by
the remote sensor.
The blinking arrow '
', indicates that the display of the
temperature is shifted on the internal sensor, while the
parameters remains set on the remote sensor.
OVERVIEW
This device is a digital thermostat for room temperature control
with the possibility to choose between different regulation modes
and related set-point temperatures: Comfort, Reduction, Off/
Antifreeze.
The device can be used both in heating and cooling systems, and it
is featured with a wide backlit display for the visualization of all
the functional indications and the detected room temperature.
The detection of the room temperature can be performed by the
internal sensor or by a remote sensor (optional).
Furthermore, the device offers the possibility to set the value of
the antifreeze temperature and the Offset regulation on the
internal and remote sensor.
STARTING UP
When starting up for the first time:
- Power on the device (see section 'INSTALLATION' at point
' 4 ').
- Set the operating mode of the thermostat (user parameter
' H_C '): Heating (factory default) or Cooling.
Regulation mode set-up
There are two modes to regulate the room temperature that can
be chosen by pressing '
'.
Comfort: the thermostat sets the room temperature in comfort
mode; this is normally the chosen temperature during
day-time.
Economy: the thermostat sets the room temperature in economy
mode; this is normally the chosen temperature during
night-time.
Comfort and Economy temperatures regulation
When in normal functioning mode, the display shows the detected
room temperature and the icon related to the set regulation mode.
To visualize the related set set-point temperature push once one of
the key '
' or '
': the display visualizes the set-point
temperature and the icon '
' (showing that the set-point
SET
temperature is being displayed).
The icon '
' lit together with the blinking icon '
SET
that the display is showing the 'Comfort' set-point temperature or
it can lit together with the blinking icon '
display is showing the 'Reduction' set-point temperature.
Pressing the keys '
' and '
' it is possible to modify the
displayed set-point temperature. Pressing the key '
display is showing the 'Comfort' set-point temperature, the
display switches to the 'Reduction' set-point visualization. Vice
versa, if the display was showing the 'Reduction' set-point,
pushing the key '
' the display switches to the 'Comfort' set-
point visualization.
Pushing the key '
' or after a few seconds of inactivity, goes
back to the visualization of the detected room temperature.
Note: Usually, in order to get a temperature reduction at
night, the economy temperature should have a lower value
than the comfort one.
Temperature display
During normal operation the display shows the room temperature
detected by the internal sensor, distinguished by the icon '
the room temperature detected by the remote sensor (if
connected) distinguished by the icon '
'.
The detected temperatures are displayed corrected by the set
Offset value.
In case the parameter ' rEG ' is set on ' EHt ', but the remote
sensor is not connected or is damaged, the display shows the icon
'
' with the blinking '
' arrow showing that the regulation of
the temperature has been automatically shifted on the internal
sensor, while remaining the parameter set on ' EHt ' (external
sensor).
Switching off - Antifrost function
To switch off the thermostat press the '
The display will show the writing ' OFF ' and the symbol '
If the thermostat has been set in the heating mode, the Antifrost
function will be active and the '
' symbol will appear on the
display; in this case the room temperature will be controlled
relying on the value set for the Antifrost temperature (see chapter
'SETTING THE USER PARAMETERS').
Backlighting
The display backlight turns on whenever and button is pressed. It
turns off automatically 20 seconds after the last pression of a
button.
