7. Operating mode
The timer-thermostat 02910 is able to regulate 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
•
AUTO
: lets you set a control program that compares the room temperature with the value set for each
quarter of an hour of the current day; the user defines three levels of temperature distributed over 24 hours
which can then be varied for each day of the week.
•
Timed manual
: starting from AUTO mode, this lets you activate MANUAL operation of the timer-thermostat
for any period of time at the end of which the device will return to AUTO mode.
•
Away
: lets you set the set-point in order to achieve significant energy savings during periods when the user
is away
•
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 timer-thermostat has been suitably configured, you can remotely
activate the following modes:
•
Remote reduction
: lets you vary the set points of MANUAL adjustment to obtain energy savings.
•
Remote activation
: lets you activate the system remotely, setting AUTO operation.
•
Summer/Winter switching
: the multi-function input automatically switches the timer-thermostat onto
air-conditioning mode (when on) or heating mode (when off).
The operating mode is selected via the SETTINGS menu or with the shortcut keys.
7.1 Switched off (OFF)
With this mode on, the timer-thermostat is turned off and you cannot make any adjustments; in this case,
the
icon is displayed above the temperature indicator.
In this mode you cannot perform any operations other than activating the menus or changing the view
mode.
