2. Remove the batteries, prying them out with the aid of a tool if
necessary.
3. Insert the new batteries, which must be alkaline 1.5V type AA.
4. If necessary, reset the device by means of button N shown in
Fig. 4; DO NOT USE NEEDLES OR TOOLS THAT COULD
IRREPARABLY DAMAGE THE Chronostat.
5. Check that the time is set correctly; adjust the setting if necessary.
CONNECTION TO A TELEPHONE INTERFACE
The chronostat offers the option of connecting a telephone interface with
continuous operation (latching relay) to terminals 8 and 9.
Use of a suitable telephone interface does not require any setting
to be made on the chronostat; for directions on using the telephone
interface see the instruction manual provided.
Via a telephone interface it is possible to turn the chronostat Off or
turn it On in the Permanent Manual mode.
Depending on the commands received from the telephone interface the
chronostat will act according to the following operating logic:
1. Telephone interface contact closed:
The chronostat will switch into the 'Permanent Manual' mode: the
'
' and '
' symbols will be shown on the display.
2. Telephone interface contact open, after (and only after) a previous
closure, if no buttons have been pressed (Manual/Off):
The chronostat will be switched off and the word 'OFF' will be
displayed along with the '
' symbol. If the 'Antifreeze' function
is active the '
' symbol will be displayed.
IMPORTANT: the commands input by pressing the control
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.
