7.3 Away

This mode is useful to achieve energy savings quickly and effectively whenever the user leaves the reg-
ulated room. 
In "Away" mode the system makes the adjustment according to the "away temperature" setpoint 

 (see 

para. 9.4.2).

The Away mode can only be activated in manual mode by touching 

The display will show the "away temperature" setpoint for approximately 2 seconds:

Activation of this mode is identified by the 

 icon above the temperature indicator:
