Electrical Connections
Secure the wires in the specific cable
clamp to guarantee the correct positioning
within the equipment.
6.2.1 Power connection
When installing a single Corolla 1000 Series the
connection must be made in accordance with
current regulations regarding electrical safety,
using a multi sheathed cable H05 VV-F-3GI
with minimum section of the conductors of 1,5
mm
2
, suitably protected against moisture,
abrasions and incidental contact.
The power cord is to be connected to the
switch, located behind the boiler control panel.
To access the switch, remove the protective
sheet metal by removing the screws connect-
ing. The protective conductor (earth) terminal
is to be connected to the general earth strip
next to the switch. Secure the cable using the
provided cable clamp to ensure proper place-
ment within the equipment and to prevent
from contacts with components at high tem-
perature (burner etc..)
The length of the grounding cord should
be higher than other conductors (phase, neu-
tral). In case of disconnection of the power
cord the cables of the conductors are strained
before the grounding one.
The rubber cableguides placed on the
structure of the equipment have not to be re-
moved because their purpose is to protect the
cables from wear that occurs in direct contact
between cable and frame equipment. To pass a
cable is sufficient to drill the cableguides.
6.2.2 Master board connection
Il The master panel must be connected to the
mains autonomously, following the same in-
structions in the previous paragraph.
Furthermore, the master panel must be con-
nected to Corolla 1000 Series through the ap-
propriate bus connection to be made with a
twin cable. Need to connect one end of the bi-
polar cable to the terminal on the master panel
(see Figure 10 ) and the other end to one of the
terminals at the ends of the door panel-control
units via one of the holes. Figure 11 shows the
terminal of the switch left of the machine, but
the connection can be made either on the ter-
minal is also situated in the far right..

6.2.3 Connections to thermoregulation devi-
ces
The heating units Corolla 1000 Series are
equipped with a system of supervision and
management very versatile, can handle up to
three separate circuits operating at different
temperatures. In the following pages will ex-
plain how to connect the output signal to the
specific points on the terminal board (see i
Figure 13).
For the temperature control circuits and low
voltage cables may be used H05-VV-F cables
with outer diameter 5mm minimum, taking
care to fix them in the cable holders.
6.2.4 Pump Connections
COROLLA Serie 1000 regulation system in-
cludes the simultaneous management of up to
three circulators.
Therefore, if a low temperature circuit
supplied by its own circulator is present and a
general pump is to be installed on the system, it
will be necessary to choose which one of the
two devices should be managed by the sys-
tem's electronics.
During the first operation of the system, this
operation is performed by authorized Tech-
nical Assistance Centre.
This operation is carried out by setting the rel-
evant parameter (n.34 in parameters list).
