1.10 REMOTE CONTROLS AND ROOM
CHRONO-THERMOSTATS (OPTIONAL)
The boiler is prepared for the application of room chrono-thermo-
stats or remote controls, which are available as optional kits
(Fig. 9).
All Immergas chrono-thermostats are connected with 2 wires
only.
Carefully read the user and assembly instructions contained in
the accessory kit.
Disconnect power to the unit before ma-
king any electrical connections.

On/Off Immergas digital chrono-thermostat.
The chrono-thermostat allows:
- set two room temperature value: one for day (comfort tempera-
ture) and one for night (reduced temperature);
- set a weekly programme with four daily switch on and switch off
times;
- selecting the required function mode from the various possible
alternatives:
• manual mode (with adjustable temperature);
• automatic mode (with set programme);
• forced automatic operation (momentarily changing the tem-
perature of the automatic program).
The chrono-thermostat is powered by two 1.5V LR 6 type alkaline
batteries.
“Comando Amico Remoto” (Remote Control Device) V2
(CARV2) with climate chrono-thermostat function.
In addition to the functions described in the previous point, the
CARV2 panel enables the user to control all the important infor-
mation regarding operation of the appliance and the heating sy-
stem with the opportunity to easily intervene on the previously set
parameters, without having to go to where the appliance is instal-
led.
The panel is provided with self-diagnosis to display any boiler
functioning anomalies.
The climate chrono-thermostat incorporated into the remote pa-
nel enables the system flow temperature to be adjusted to the
actual needs of the room being heated, in order to obtain the desi-
red room temperature with extreme precision and therefore with
evident saving in running costs.
The CARV2 is fed directly by the boiler by means of the same 2 wi-
res used for the transmission of data between the boiler and devi-
ce.
“Comando Amico Remoto” (Remote Control Device) V2 or
On/Off chrono-thermostat electrical connection (Optional).
The operations described below must be
performed after having removed the vol-
tage from the appliance.
Any thermostat or On/Off environment chrono-thermostat must
be connected to clamps 40 and 41 eliminating jumper X40.
Make sure that the On/Off thermostat contact is of the “clean”
type, i.e. independent of the mains voltage, otherwise the P.C.B.
would be damaged.
Any Comando Amico Remoto remote control V2 must be con-
nected to terminals 40 and 41, eliminating jumper X40 on the
The boiler can only be connected to one remote control.
If the Comando Amico Remoto remote control V2 or
any other On/Off chrono-thermostat is used arrange
two separate lines in compliance with current regula-
tions regarding electrical systems.
Ensure elimination of this risk before making the boiler
electrical connections.
