7.4.7 External probe alarm temperature
The menu, via
and
, lets you set the temperature limit (read by the external probe)
at which the thermostat switches off the heating system and triggers an alarm (useful to protect
underfloor systems against overheating).
To view this menu, the external temperature probe must be set as a "limitation" (see par.
7.6).
7.5 Calibration setting
This menu lets you "calibrate" the temperature read by the thermostat.
Via
and
, you can add or subtract (at intervals of 0.1°) a fixed amount from the tempera-
ture detected by the thermostat to make it equal, for example, to that of a sample thermometer.
CAUTION: For correct calibration it is recommended to wait until the thermostat has been on for
at least 1 hour in a room at constant temperature.

7.6 External probe setting
This menu lets you configure how to use the external temperature probe (installed according to the
instructions in par. 4 .2)
Via
and
you can select the following options:
•
OFF
: the external probe (although physically present) is ignored by the device.
•
Adjustment (the measured temperature flashes)
: by enabling this function, the thermostat will regu-
late the temperature of the environment based ONLY on the temperature detected by the external probe
(the temperature measured by the thermostat is ignored).
The temperature shown on the display will be that of the external probe identified by the
icon.
•
Display (the temperature measured by the thermostat and that of the external probe are shown
alternately on the display)
: the external probe is only used to display the temperature in another
environment.
On standby the display will alternate views of the internal temperature (measured by the thermostat) and
external temperature (measured by the probe) and identifiable by the
icon.
•
Limitation (the icon flashes)
: mode used for systems with underfloor heating.
In the associated submenu you set the limitation temperature, that is the one, read by the external probe
immersed in the screed, that is considered an excessive temperature. If this threshold temperature is
reached the thermostat turns off the heating system and displays the alarm as long as the condition that
generated it remains.
At the end of this condition, the thermostat resumes its normal operation.

7.7 Multi-function input setting
This menu is used to set the operating mode of the multi-function input.
Via
and
you can select the following options:
•
: the state of the multi-function input is ignored by the device.
