You can also switch to the Vacation setting for a prolonged absence by pressing the
button. In that case, the derogation is permanent. To return to the normal oper-
ating mode, press the Manual/Auto button. If you wish to immediately return to the

4. SELECT THE HEATING, AIR CONDITIONING, OR MIXED MODE
Use the Heat/Cool button to select one of the following modes:
Heating:
Controls the heating unit according to the displayed setting.
Air-conditioning:
Controls the air-conditioning unit according to the displayed
setting.
Mixed:
The TH141 analyzes the temperature pattern and automati-
cally alternates from the comfort mode to the air-conditioning
mode.
To avoid needless switching, the automatic mode change will take at least 2 minutes
if it is required by a manual setting change and at least 15 minutes if it is due to a
quick temperature change.
Furthermore, to protect your heating and air-conditioning system, it is impossible to
shut down and restart the system within a period equal to 10% of the cycle.

5. FAN CONTROL
Use the Fan ON/OFF button to force continuous air circulation (icon
ON) or to
synchronize the fan with the heating or air-conditioning demand (icon ON).
Please note that if you set the TH141 in Vacation mode using the telephone controller
or a house automation system, the continuous air circulation will be automatically deac-
tivated during your absence.
6. TELEPHONE CONTROLLER ( )
The TH141 incorporates a telephone controller interface which allows you to switch
from the normal operating mode to the Vacation setting (
), and vice versa, using
the telephone keypad (stationary or portable). You can, for example, heat your
country house from your office on Friday, or your house from the airport or from your
car on your way back from vacation.
