SECURITY MODE
It is possible to impose a maximum temperature set point by activating this mode.
Then, it becomes impossible to exceed this set point, regardless of the current
mode (Day/Night). However, it is still possible to lower the set point at your dis-
cretion.
PROCEDURES TO ACTIVATE THE SECURITY MODE
1. To activate the Security option, adjust the set point to the desired maximum tem-
perature.
2. Simultaneously press down the two buttons for more than 13 seconds, until the
icon appears (note that the °C or °F symbol will blink after 3 seconds, but
continue to keep both buttons pressed down).
3. Release the buttons. The thermostat is now locked.
PROCEDURES TO DEACTIVATE THE SECURITY MODE
1. To deactivate the Security mode, start by cutting off the thermostat power at circuit
breaker and wait at least 20 seconds.
2. Turn the thermostat power back on and the icon will blink for a maximum of
5 minutes.
3. Simultaneously press down both buttons for 13 seconds. After 13 seconds, the
icon will disappear and the degrees symbol (°C or °F) will stop blinking, indicating
that the Security mode is deactivated. Release the buttons.
PARAMETERS SAVING AND POWER FAILURES
The thermostat saves some parameters in a non-volatile memory to be able to
recover them after being shut off (a power failure, for example). These parameters
are the set point, the state of the Security mode, the maximum symbol of the
Security mode and the Celsius/Fahrenheit symbol. These parameters are saved
every minute if any changes are made.
The Security mode is reactivated if it was previously activated. However, the icon
will blink for 5 minutes, during which it is possible to deactivate the Security mode
by pressing down both buttons simultaneously for 13 seconds. If this is not done,
the Security mode will remain activated and the icon will stop blinking.
