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 ‘ ’ icon will flash to indicate that
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
boxes by means of the two holes for screws (distance between
centres: 60 mm or 85mm), taking care to pass the wires through
the opening as shown in Fig. 3.
4.
Make the electrical connections following the connection diagram
in Fig. 4.
5.
Fit the chronostat onto the wall mount plate, first matching up
the teeth on the base with the holes provided on the plate and
then pressing downward on the device until the plastic teeth of
the plate click into place; then fix the chronostat body to the
wall mount plate through the two screws supplied which must be
mounted in the battery holder (Fig. 3).
6.
Insert the batteries in the battery compartment (
O
in Fig. 1); see
paragraph ‘ HOW TO INSERT/REPLACE THE BATTERIES ’.
