Remote Controls And Room Chrono-Thermostats (Optional); External Temperature Probe - Immergas MAGIS PRO ERP Instruction And Recommendation Booklet

fications shown on the hydronic unit data plate.
The hydronic units are supplied complete with
a special "X"-type power cable without a plug.
The power supply cable must be connected to a
230V ±10% / 50Hz mains supply respecting L-N
polarity and earth connection;
must also have a multi-pole circuit breaker with
class III over-voltage category.
To protect from possible dispersions of DC volt-
age, it is necessary to provide a type A differential
safety device.
When replacing the power supply cable, contact a
qualified company (e.g. the Immergas Authorised
After-Sales Technical Assistance Service). The
power cable must be laid as shown (Fig. 1-3).
If the fuses on the electronic boards must be
replaced, use:
- P.C.B.: a T 3.5 A fuse
- heat pump communication board: a T 5.0 A
fuse
For the main power supply to the appliance,
never use adapters, multiple sockets or exten-
sion leads.
1.8 REMOTE CONTROLS AND
ROOM CHRONO-THERMOSTATS
(OPTIONAL).
The hydronic module is set up for room
chrono-thermostats or remote controls, avail-
able as optional kits (Fig. 1-6). 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 Immergas digital chrono-thermostat.
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 operation (with adjustable tempera-
ture).
• automatic operation (with set programme).
• forced automatic operation (momentarily
changing the temperature of the automatic
programme).
The chrono-thermostat is powered by two 1.5V
LR 6 type alkaline batteries.
• Comando Amico Remoto Remote Control
Device (CAR ) with climate chrono-ther-
V2 V2
mostat function. In addition to the functions
described in the previous point, the CAR
1-6
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
this network to where the appliance is installed. The panel
is equipped with self-diagnosis to show any
appliance operating anomalies on the display.
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 or cooled, in order
to obtain the desired room temperature with
extreme precision and therefore with evident
savings in running costs. The CAR

2 wires used to transmit data between the
hydronic module and the device.
Important: the hydronic module is set up to be
able to work with two CAR
separate hydraulic zones.
Comando Amico Remoto Remote Control
or On/Off chrono-thermostat electrical con-
nections (Optional). The operations described
below must be performed after having removed
the voltage from the appliance.
-On/Off 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 40-1 / 41-1 for zone 2. Make sure
that the On/Off thermostat contact is of the
"clean" type, i.e. independent of the mains volt-
age, otherwise the P.C.B. would be damaged.
- Comando Amico Remoto remote control
V2
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
ing another one for zone 2 on terminals 40-2
and 41-2, being careful not to invert polarity
in the connections.
The connections must be made on the terminal
board inside the appliance control panel as de-
scribed in figure 1-5.
Important: if the Comando Amico Remo-
to Remote Control
chrono-thermostat is used, arrange two separate
lines in compliance with current regulations re-
garding electrical systems. The hydronic module
pipes must never be used to earth the electrical
or telephone system. Make sure this does not
happen before making the hydronic module
electrical connections.

1.9 EXTERNAL TEMPERATURE PROBE.

In general, Magis Pro ErP uses the probe stand-
ard supplied on the condensing unit to read the
outdoor temperature.
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. 1-7), which is available as an optional kit.
Refer to the relative instruction sheet to position
the optional external probe.
The probe can be connected directly to the hy-
dronic module electrical system and allows the
system flow temperature to be set automatically
based on the outdoor temperature in order to

The external probe always operates when con-

bination with Immergas chrono-thermostats.

N.B.: if the system is divided into two zones,
the flow temperature is calculated based on the
