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
making 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
(CAR
V2
) with climate chrono-thermostat function.
In addition to the functions described in the previous point, the
CAR
V2
panel enables the user to control all the important infor-
mation regarding operation of the appliance and the heating sys-
tem with the opportunity to easily intervene on the previously set
parameters, without having to go to where the appliance is in-
stalled.
The panel is provided with self-diagnosis to display any boiler
functioning anomalies.
The climate chrono-thermostat incorporated into the remote
panel enables the system flow temperature to be adjusted to the
actual needs of the room being heated, in order to obtain the de-
sired room temperature with extreme precision and therefore
with evident saving in running costs.
The CAR
V2
is fed directly by the boiler by means of the same 2
wires used for the transmission of data between the boiler and de-
vice.

V2
or On/
Off chrono-thermostat electrical connection (Optional).
The operations described below must be
performed after having removed the
voltage from the appliance.
Any On/Off room thermostat or chrono-thermostat must be con-
nected to terminals 44/40 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 44/40 and 41, eliminating jumper X40 on the
P.C.B. (Fig. 40).
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 regulations
regarding electrical systems.
Ensure elimination of this risk before making the boiler
electrical connections.
