INSTALLATION

• Unscrew front and back case with a screwdriver, than take off the front case (fig. 1)

• Open relay case with screwdriver and take off the relay case (fig. 2)

• Connect all wires properly (NC=normal close, NO=normal open, COM=common, S1-S2=terminals of the remote switch for the temperature reduction) (fig. 3, 8 e 9)

Cover the relay case and screw it properly with screwdriver (fig. 4)

• Mount and fix back case in the wall with screwdriver (fig. 5)

Install 2× 1,5 Vdc LR03 AAA (fig.6)

Cover front case and back case properly (fig. 7)

SWING

It's possible to choose two positions for the jumper pin which fix the swing: 0,4 or 0,6^ . The function is available only after RESET.

OPERATING MODES

The thermostat always work in the continuous operating mode to the comfort temperature in the heating mode (the thermostat switch on/off the boiler).

When the boiler is on, will appear on the display the symbol

TEMPERATURE SETTING

Set the comfort temperature through directly push on the display:

• Push the display, the display willa come blue back light for 15 seconds

C83

continue TEMPERATURE SETTING

• If during this 15 seconds you push once again the display then the number on the display will be blinking and you can set the temperature.
• Push on the left side if you want to increase the set temperature (fig. 10), and push the right side instead if you want to decrease the set temperature (fig. 11)
• Then wait 10 seconds and on the display will go back the room temperature
  When the boiler is on, will appear on the display the symbol

TEMPERATURE REDUCTION BY REMOTE SWITCH

It's possible to connect to the input terminals S1-S2 of the thermostat a remote switch for having the function temperature reduction (fig. 12):

• Switch open (OFF): the working temperature is the setting temperature (ex.: 21^ )
• Switch close (ON): the working temperature is the setting temperature less 3^ (ex.: 21-3 = 18 °C).

It is not possible to connect multiple S1-S2 contacts in parallel.

Max length allowed 20m

LOW BATTERY INDICATOR

When low battery occur then appear on the display the symbol

RESET FUNCTION

When press the RESET KEY, on the electronic board (pcb), the thermostat will go on the basic conditions: the values of the temperature comfort will be as the user has programmed. Besides it will be switch on the right Swing mode as from the jumper pin (see pag. 10).
