5.4 Locking the interface via PIN
The thermostat lets you set a password (see par. 7.12) which inhibits any change to the operating mode
(eg switching from Manual to OFF), limits setting the temperature values and, more generally, blocks
access to the configuration menu.
This feature is useful to prevent the thermostat being used by unauthorized persons: the device prompts
you to enter the PIN, indicating a shutdown with the icon.

6. Operating mode
The thermostat 02950 is able to adjust the temperature according to the following operating modes:
• Switched off (OFF): switches the system off
• Manual (ON): lets you set the environment temperature set-point manually
• Away: is an intermediate mode between manual and antifreeze that lets you set the set-point in order to
achieve significant energy savings during periods when the user is away
• Nighttime reduction: this mode, which can be activated locally, is useful for changing the manual adjustment
set point in the hours of nighttime operation.
• Antifreeze: used to set a minimum temperature level to avoid damage to pipework or prevent the temper-
ature from falling below a safety level.
In addition, if the multi-function input of the thermostat has been suitably configured, you can remotely activate
the following modes:
• Remote reduction: conceptually similar to nighttime reduction, it acts on the comfort set point instead of
the manual set point
• Remote activation: lets you activate the system remotely by setting the comfort set point
The operating mode is selected via the SETTINGS menu (see chap. 7).
