1.8 REMOTE CONTROLS AND
ROOM CHRONOTHERMOSTATS
OPTIONAL.
e indoor unit is prepared for the application
of room chrono-thermostats or remote controls,
which are available as optional kits (Fig. 6). A
maximum of 2 thermo-regulators can be applied
directly to the appliance.
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 chrono-thermostat. The
chrono-thermostat allows:
- set two room temperature value: one for day
(comfort temperature) and one for night
(reduced temperature);
- set a weekly programme with four daily
switch on and switch o times;
- selecting the required function mode from
the various possible alternatives:
• manual operation (with adjustable tempera-
ture).
• automatic operation (with set programme).
• forced automatic operation (momentarily
changing the temperature of the automatic
programme).
e 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-ther-
mostat function. In addition to the functions
described in the previous point, the CAR
V2
panel enables the user to control all the im-
portant information regarding operation of
the appliance and the heating system with the
opportunity to easily intervene on the pre-
viously set parameters, without having to go
to where the appliance is installed. e panel
is equipped with self-diagnosis to show any
appliance operating anomalies on the display.
e climate chrono-thermostat incorporated
into the remote panel enables the system ow
temperature to be adjusted to the actual needs
of the room being heated or cooled, in order
to obtain the desired room temperature with
extreme precision and therefore with evident
savings in running costs. e CAR
V2
is powered
directly by the hydronic module by the same
2 wires used to transmit data between the
hydronic module and the device.
Important: the indoor unit is set up to be able to
work with two CAR
V2
used to control two sepa-
rate hydraulic zones. In this case the appliance
is controlled by the CAR
V2
of zone 2.
Comando Amico Remoto Remote Control
V2
or On/O chrono-thermostat electrical con-
nections (Optional). e operations described
below must be performed aer having removed
the voltage from the appliance.
-On/O ambient thermostat or chrono-ther-
mostat: must be connected to the 40-1 / 41-1
terminals, eliminating the X40-1 jumper for
zone 1 and 40-2 / 41-2 for zone 2. Make sure
that the On/O thermostat contact is of the
“clean” type, i.e. independent of the mains volt-
age, otherwise the P.C.B. would be damaged.
-
V2
Comando Amico Remoto remote control
must be connected to terminals 42-1 / 43 for
zone 1 and 42-2 / 43 for zone 2, keeping the
X40-1 jumper for the CAR
V2
in zone 1 and add-
ing another one for zone 2 on terminals 40-2
and 41-2, being careful not to invert polarity
in the connections.
e connections must be made on the termi-
nal board inside the indoor unit control panel
(Fig. 5).
1.9 EXTERNAL TEMPERATURE PROBE.
In the condensing unit there is an external probe
as standard. is can be used as an external probe
of the indoor unit.
If the condensing unit is positioned in an area
that is not suitable for temperature reading, it is
advisable to use an additional external probe (Fig.
7), which is available as an optional kit.
Refer to the relative instruction sheet to position
the optional external probe.
For the proper operation of the optional probe it
must be connected where envisaged (Fig. 5) and
then it must be enabled (see Par. 3.10).
e probe allows the system ow temperature
to be set automatically based on the outdoor
temperature in order to adapt the heat or cooling
provided to the system. e probe can work in
combination with both chrono-thermostats
and CAR
V2
.
e correlation between system ow temperature
and outdoor temperature is managed dierently
based on whether the system is managed directly
by the indoor unit or by the CAR
V2
; the param-
eters set on the chrono-thermostat take priority
over those set on the indoor unit.
- Indoor unit: the system ow temperature is
determined by the setting on the "Heat regu-
lation" menu and by the "User" menu for the
oset values based on the curves shown in the
diagram (Fig. 8).
- CAR
V2
: the system ow temperature is deter-
mined by the setting on the central heating
selector (which can be adjusted from 0 to 9)
and by the "Oset" value on the "Regulat." menu
based on the curves shown in the correspond-
ing instructions booklet.
N.B.: if the system is divided into two zones,
the ow temperature is calculated based on the
zone with the higher temperature in central
heating mode and with the lower temperature
in cooling mode.
e electric connection of the external probe
must be made on terminals 38 and 39 on the
terminal board on the indoor unit control panel
(Fig. 5).
