1.7 REMOTE CONTROLS AND ROOM
CHRONO-THERMOSTATS
(OPTIONAL).
The boiler is prepared for the application of room
chrono-thermostats or remote controls, which
are available as optional kits.
All Immergas chrono-thermostats are connected
with 2 wires only. Carefully read the user and
assembly instructions contained in the acces-
sory kit.
• On/Off digital Immergas chrono-thermostat
(Fig. 1-4). The chrono-thermostat allows:
- set two room temperature value: one for
daytime (comfort temperature) and one for
night-time (reduced temperature);
- set a weekly program with four daily switch on
and switch off times;
- select the required operating mode from the
various possible alternatives:
- manual mode (with adjustable temperature).
- automatic mode (with set program).
- forced automatic mode (momentarily
changing the temperature of the automatic
program).
The chrono-thermostat is powered by two 1.5V
LR 6 type alkaline batteries.
• There are two types of remote controls availa-
ble: Comando Amico Remoto remote control
V2
(CAR
V2
) (Fig. 1-5) and Super Comando Amico
Remoto remote control (Super CAR) (Fig. 1-5)
both with a climate chrono-thermostat opera-
tion. In addition to the functions described in
the previous point, the chrono-thermostat
panels enable the user to control all the im-
portant information regarding operation of
the appliance and the central heating system
with the opportunity of easily intervening on
the previously set parameters without having to
go to the place where the appliance is installed.
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 desired 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 device.
Important:
if the system is subdivided into areas
using the relevant kit, the CAR
V2
and the Super
CAR must be used with its climate thermostat
function disabled, i.e. it must be set to On/Off
mode.

.
The
operations described below must be performed
after having removed the voltage from the appli-
ance. Any On/Off room chrono-thermostat must
be connected to clamps 40 and 41 eliminating
jumper X40 (Fig. 3-2). 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 CAR
V2
or Super
CAR must be connected by means of terminals
IN+ and IN- to terminals 42 and 43 on the
P.C.B. (in the boiler), eliminating jumper X40
and respecting polarity (Fig. 3-2). Connection
with the wrong polarity prevents functioning, but
without damaging the CAR
V2
The boiler can only
be connected to one remote control.
Important: if the Comando Amico Remoto
remote control
V2
is used, arrange two separate
lines in compliance with current regulations
regarding electrical systems. No boiler pipes
must ever be used to earth the electric system or
telephone lines. Ensure elimination of this risk
before making the boiler electrical connections.
1.8 EXTERNAL TEMPERATURE PROBE
(OPTIONAL).
The boiler is designed for the application of the
external temperature probe (Fig. 1-6), which is
available as an optional kit. Refer to the relative
instruction sheet for positioning of the external
probe. The probe can be connected directly to
the boiler electrical system and allows the max.
system flow temperature to be automatically de-
creased when the external temperature increases,
in order to adjust the heat supplied to the system
according to the change in external temperature.
The external probe always operates when con-
nected, regardless of the presence or type of
room chrono-thermostat used and can work in
combination with Immergas timer thermostats.
The correlation between system flow temperature
and external temperature is determined by the
parameters set in menu “M5” under item “P66”
according to the curves represented in the dia-
gram (Fig. 1-7). The electric connection of the
external probe must be made on clamps 38 and
39 on the boiler P.C.B. (Fig. 3-2).
