12.10.2 Example of remote switching on/off of the
chronothermostat, connected to a telephone
programmer with a NO (normally open) contact.
•
Close contact of the programmer (change of status):
causes the forcing to comfort permanent manual status with the display
of the associated symbols/setpoint and the icon "e" flashing, which
indicates the arrival of a forcing on the part of the telephone. Next, it will
be possible to change the working mode on site, by manually actuating the
buttons of the chronothermostat, even though the contact of the telephone
programmer remains closed. In the first change, the "e" icon will
become fixed indicating the end of the telephone forcing status and showing
the status of the contact still closed.
•
Opening of the contact of the programmer (change of status):
causes forcing to the operating status OFF
(chronothermostat override)") with antifreeze function unless disabled. The
screen displays the word OFF (fixed) and the flashing "e" icon, which
indicates the arrival of a forcing on the part of the telephone. Next, it will be
possible to return to the chronothermostat's normal operation by pressing
the button 7 and the "e" icon will switch off, indicating the end of the
telephone forcing.
NOTE: the contact open and close commands are operational in a period
of 10 sec.
