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.

Tap 

 to confirm your choice.

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.
Tap 

 to confirm your choice.

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.
