tors) need a high value (example: setting a room temperature to 20 °C and the ther-
mal differential to 0,3 °C, in winter the system will switch on when room tempera-
ture falls to 20 °C and will switch off when it reaches 20,4 °C).
The set value will be viewed with the wording " 0.3". Use the keys
regulate from 0,2 to 2,5 °C.
Factory settings: 0,3 °C

5.7 Timer

If the remote control input is closed for a time going from 1 second to 5 seconds
the thermostat is activated with the timer (see paragraph 4.2). Use the keys
and to regulate from 0,5 hours to 5 hours with steps of 0,5 hours.
Factory settings: 2 ore

5.8 Reset

The " " sign while blinking indicates the possibility to use the function "reset"
which will bring the device to the factory settings
The reset will be executed keeping the
and buttons pressed together, for at least 5 seconds: as confirmation all dis-
play symbols will be on

6 Operation

6.1 Switching on

When the feed is from the mains, it will take about 8 seconds to switch on (the time
needed to acquire a temperature value). During the switching on phase there is the
test of the entire display and the firmware version is then viewed (example F0.0).

6.2 Ordinary operation

In normal operation the device will view the measured temperature and the state of
the relay (using the appropriate symbol
ding on the set operating function).

If the measured temperature exceeds the room temperature measuring range, the
display will flash the wording "+40.0" if the temperature exceeds the maximum
limit, or "–00.0" if the temperature falls below the minimum limit.

Any manual work that varies the state of the output relay is transmit-
ted to the same after the back lighting of the display and the key-
board has switched off (symbols
