buttons will always have priority over the commands received
from the telephone interface.
If you press the ' ' or ' ' button on the chronostat, the device
will change its status and the '
the interface command has been overridden by a command input with
a control button.
The ' ' icon will stop flashing if the telephone interface sends the
chronostat the same command as the one made with the button or
if the telephone interface is reset. In such a case the status set by
means of the control button will not be changed and the chronostat
will be ready to receive a new command.
IMPORTANT
If an Off command is sent to the chronostat via the telephone
interface (contact open), it is a good idea to check that the
command has been executed by the chronostat by carrying out
the following realignment procedure:
1. Using the functions of the telephone interface, check that the
contact is open, sending an Off command if necessary.
2. Send a command to the telephone interface to close the
contact (the chronostat will turn on).
3. Using the functions of the telephone interface, check that the
contact is closed.
4. Send a command to the telephone interface to open the
contact (the chronostat will turn off).
During this sequence no commands should be input with
the control buttons as they have priority over the interface
commands.
