It is recommended to install the appliance strictly in compliance with all safety and law provisions in force.

Before connecting the thermostat, make sure that the supply voltage of the UNIT TO BE CONTROLLED (boiler, pump, air-conditioning system, etc.) is NOT CONNECTED and that it matches the indication given inside the appliance (250V~ max).

In case of repeated malfunctioning, please call our Technical Service. Do not tamper for any reason with any part of the thermostat.

Installation

Place this device far from any heat source or air flow, at about a 1,5mt height from the floor. Open the device pushing the clip on the base right side (Fig.1-1) then rotate the front cover leftward (Fig.1-2) and lift slightly to unfasten it (Fig.1-3).

Remove the two screws (Fig.2-D) fixing the inner protection cover for the electrical connections. Rotate leftward and release it. Fix the base on to the wall, using the horizontal (Fig.2,A-A or A-B) or the vertical (Fig.2, C-C) holes. Take care to dispose the cables in a proper manner through the window on the bottom of the base. Connect the wires to the terminal block according to the schematics (Fig.3) and place the protective inner cover again over the electric parts. Fix the screws (Fig.2-D). Dispose the optional external probe cable separately from the relay thermostat connection wires. Insert the batteries in their compartment on the display board as described (Fig.4). To close the device proceed as in the (Fig.1), reversing the sequence of operations: pairing the two left parts (Fig.1-3) then turn the front to the right side (Fig.1-2) until the hook (Fig.1-1) clicks on the base.

REPLACING THE BATTERIES

When the symbol (batteries discharged) flashes on the display, the batteries must be replaced as soon as possible. In this situation, the clock thermostat will keep on working properly for a short period of time, after which the system will be turned off permanently using the energy left over in the batteries. From this moment on, the display will show both the writing and the fixed symbol  .

FIRST START

Setting the clock
•Set the hours by + and – then OK
•Set the minutes by + and – then OK.

The device switches to OFF mode.

OFF MODE

The display shows OFF and the anti-frost function is active. Press Mode to browse active modes (Manual mode, Automatic mode, OFF mode).

AUTOMATIC MODE

In AUTOMATIC mode the thermostat sets the ambient temperature at the Comfort or Reduced T2 values, according to the programming of the micro switches. The display show AUTO to identify this modality.

SETTING THE TIME PROGRAMME

The device is equipped with a row of micro switches with 24 levers that correspond to the time slots in a day. The time programme is easy to set; simply push the levers upward (position T1) for the hours in which you want to have a COMFORT temperature, and push them downward for the hours in which you want a REDUCED T2 temperature.

SETTING THE COMFORT TEMPERATURE

You can always set COMFORT temperature by turning the central knob to the value required. You can change the temperature between 5°C and 30°C in both winter and summer operation.

SETTING THE REDUCED T2 TEMPERATURE

The REDUCED T2 temperature is set by pressing button + and –

You can change the temperature between 5°C and 30°C in 0.1°C increments in both winter and summer operation. During the setting, the icon  flashes until the new value is stored.

MANUAL MODE

In MANUAL mode the thermostat sets the ambient temperature at the COMFORT temperature, regardless of how the micro switches are programmed.
