External Temperature Probe (Optional) - Immergas MINI EOLO X 24 3 E Instructions And Warnings

• Comando Amico Remoto
with climate timer thermostat function.
In addition to the functions described in the previous point,
the CAR panel enables the user to control all the important
V2
information regarding operation of the appliance and the heating
system with the opportunity to easily intervene on the previously
set parameters, without having to go to where the appliance is
installed. The panel is provided with self-diagnosis to display
any boiler functioning anomalies. The climate chrono-thermo-
stat 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.
CAR or chrono-thermostat On/Off electric connection
V2
(Optional). The operations described below must be performed
after having removed the voltage from the appliance. Any On/Off
room chrono-thermostat must be connected to clamps 40 and
41 eliminating jumper X40 (Fig. 37). 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
must be connected to clamps 40 and 41 eliminating jumper X40
on the circuit board, paying attention not to invert the polarity
in the connections (Fig. 37). Connection with the wrong polarity
prevents functioning, but without damaging the CAR
can only be connected to one remote control.
If the CAR remote control or any other On/Off
V2
chronothermostat 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.

1.10 EXTERNAL TEMPERATURE PROBE (OPTIONAL).

V2
The boiler is designed for the application of the external temper-
ature probe (Fig. 7), 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 au-
tomatically decreased 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 connected, regardless of the presence or type of
room chrono-thermostat used and can work in combination with
Immergas chrono-thermostats. The correlation between system
flow temperature and external temperature is determined by the
position of the central heating selector switch on the boiler control
panel (or on the CAR
according to the curves shown in the diagram (Fig. 8). The electric
connection of the external probe must be made on clamps 38 and
39 on the terminal board in the boiler control panel (Fig. 37).
