8. REMOTE SWITCH-OFF
The device has two inputs (AUX) for connecting a potential-free contact to which a telephone dialler can be
connected, for example, to remotely switch the thermostat on and off using a telephone.
The contact can be in one of the following positions:
- open: normal operation (according to the programming set via keypad).
- closed: thermostat in off operation.
The remote off condition is indicated on the display by the flashing of the symbol
to differentiate it from the
keypad off
condition.
Note:
This function must be operated via the Advanced Configuration (ADV) menu. The auxiliary input parameter
must be set to “diG”.
IMPORTANT:
Remote off condition (contact closed) takes priority over any other programming and therefore
the thermostat will remain in the off condition until the contact returns to the open position.
9. THERMOSTAT RESET
This can be used to delete any settings made and reload the default settings.
Proceed as follows:
Disconnect the thermostat from the wall base and reconnect it.
While the buttons are flashing, keep the button
pressed until “dEF” appears on the display.
Resetting to default settings will clears all settings in the configuration parameters:
Time and date
Edit programs
Change temperature (T1), T2, T3
Timer setting
Advanced menu configurations
IMPORTANT:
Resetting to default parameters will not delete the wireless configurations made on the thermostat.
To delete the wireless configurations, see chapter “
7.6.6. Def 25 : Thermostat wireless configuration reset
”.
