CONNECTION TO A TELEPHONE INTERFACE

The programmable thermostat allows to connect a telephone interface with continuous operation (latching relay) to the connector ‘ B’ in Fig. 6. 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:

• Telephone interface contact closed:
  • The chronostat will switch into the ‘Permanent Manual’ mode: the “‘ and ‘‘ symbols will be shown on the display.
• 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 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:

• Using the functions of the telephone interface, check that the contact is open, sending an Off command if necessary.
• Send a command to the telephone interface to close the contact (the chronostat will turn on).
• Using the functions of the telephone interface, check that the contact is closed.
• 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.

BACKLIGHTING
The display backlight turns on whenever and button is pressed. It turns off automatically 20 seconds after the last pressing of a button.

HOW TO INSERT | REPLACE BATTERIES
