It is recommended to install the device in strict accordance with the safety regulations and laws in force. Before making any connection, make sure that the main switch is off.

INSTALLATION

Install the device away from heat sources and drafts, about 1.5m from the floor.
Open the device by pressing the small tab on the underside of the base (Fig.1 A). Turn the front panel upwards (Fig.1 B) and lift it slightly to release it (Fig.1 C).

Attach the base to the wall, using the horizontal (Fig.2 A-A) or diagonal distance (Fig.2 B-B).

Remove the internal protection covering the terminals by unscrewing the screw (Fig.2 C) and turning the cover upwards. Attach the base to the wall, using the horizontal (Fig.2 A-A) or diagonal distance (Fig.2 B-B). Insert the cables through the opening at the bottom and connect them to the terminal board (Fig.4) then replace the internal cover and tighten the screw (Fig.2 C).

Insert the batteries in the front panel (Fig.3).

To close the device, proceed as before but reversing the sequence of operations: match the upper sides of the two parts (Fig.1 C) then turn the front panel downwards (Fig.1 B) until the lower hook clicks (Fig.1 A) on the base.

REPLACING THE BATTERIES

When the symbol flashes (batteries low) it is necessary to replace them. Proceed as indicated in the installation instructions (Fig. 1 and Fig.3). Put the cover back on the base before performing any operation.

DESCRIPTION OF CONTROLS AND OPERATION

The controls consist of a ring with four positions identified by the arrows ◄ ►▲▼ with a central button OK. Press the ring in correspondence with the arrow to activate one button at a time. Press the OK button in the centre. Use the arrow buttons to change the time and temperature values or to select the options, the central OK button usually confirms the settings.

FIRST START-UP

Set the clock

• Set the format 24H or 12H using ▲▼, then OK.
• Set the hour using ▲▼, then OK.
• Set the minutes using ▲▼, then OK. OFF and the clock appear on the display.

Pair with the radio receiver RCV by means of the "rAd" parameter in the installer menu. The procedure is performed at the factory but it is possible to repeat it (for example when a device is replaced).
First prepare the receiver RCV by following the instructions.

OFF MODE

The antifreeze function is active. Press for 3 seconds:
▼ to set the clock (as above).
▲ to set the season mode Summer/Winter (standard: WINTER).
◄ to go from OFF to ON and vice versa. Press OK for 10 seconds to enter the Installer Menu.

ACTIVE MODES

Ambient temperature is always in the foreground.
Press OK to show the clock or the set-point temperature in the upper right corner.
Press ► to select AUTO, MAN, MAN ECO modes (standard: AUTO).

MANUAL AND MANUAL ECO

(Fig.7)
Press ▲ or ▼ to change and save the temperature set-points.
MAN = comfort temperature (standard: WINTER = 20,0°C / SUMMER = 25,0°C).
MAN ECO = economy temperature (standard: WINTER = 16,0°C / SUMMER = 28,0°C).

AUTOMATIC MODE

(Fig.8 and Fig.9)
The display shows in its lower part:

• █ hours set at Comfort temperature (t1).
• hours set at Economy temperature (t2).

The set-point temperature (t1 or t2) depends on the saved time program and changes automatically.

TIME PROGRAM

Hold ▼ 3 seconds, the current time of day appears in the upper righ corner

SET and the symbol █ related to the current time flash.
Select the desired temperature per every hour along the day.
Press ▲ to set t1 temperature.
Press ▼ to set t2 temperature.
Press ◄ ► to move along the hours without changing the settings.
Press OK to confirm the program settings.

The display shows t1 (Comfort) temperature first and t2 (Economy) soon after

Change t1 (Comfort) by ▲▼ then OK
(standard: WINTER = 20,0°C / SUMMER = 25,0°C).
Change t2 (Economy) by ▲▼ then OK
(standard: WINTER = 16,0°C / SUMMER = 28,0°C).

WINTER MODE

The Comfort temperature is higher than the Economy temperature (t1>t2). When Tamb < Tset (Room temperature < Set temperature), the heating is activated .

SUMMER MODE

The Comfort temperature is lower than the Economy temperature (t1<t2). When Tamb > Tset (Room temperature > Set temperature), the cooling is activated .

RADIO COMMUNICATION

Normally, the display shows the symbol fixed (Fig.7 e Fig.9). If flashes, check the devices, try to repeat the pairing procedure or change its position.

INSTALLER MENU

On OFF mode, press OK for 10 seconds to enter the Installer Menu.
Press ◄ ► to select the options;
Press ▲ ▼ to change the values;

• AF = Antifreeze threshold (standard 6.0°C);
• HYS = Temperature differential (standard 0.2°C);
• OFS = Temperature offset correction (standard 0.0°C);
• °C = Select degrees Celsius/Fahrenheit (standard Celsius);
• rAd = (only DPT R, DPT VR). Press ▲ to select YES and confirm by pressing ▲ again. At the end of the pairing procedure, "rdY" will appear on the display if it was successful, "Err" if it was unsuccessful;
• CLR = Press ▲ to select YES and confirm by pressing ▲ again. Wait 4 seconds for the automatic reset. Reset factory values.

Press OK to exit the installer menu.
