11.1 CONNECTING THE ROOM THERMOSTAT
The connections in terminal block M1 are high voltage (230 V). Before making connections, make sure the appliance is
disconnected from the power supply. Respect polarity L (LIVE) - N (NEUTRAL).
To connect the Room Thermostat to the boiler, proceed as described below:
•
switch off the boiler;
•
access the terminal block
M1
;
•
remove the jumper from the ends of contacts
1-2
and connect the wires of the Room Thermostat;
•
switch on the boiler and make sure the Room Thermostat works correctly.
11.2 ACCESSORIES NOT INCLUDED IN THE SUPPLY
11.2.1 EXTERNAL SENSOR
To connect this accessory, see figure to side (terminals 3-4
only for models 1.12 - 1.24, terminals 4-5 only for models 24 -
28 - 33) and the instructions supplied with the sensor.
SETTING THE "Kt" CLIMATE CURVE
When the external sensor is connected to the boiler, the
electronic board adjusts the flow temperature calculated
according to the set
Kt
coefficient. Select the required curve by
pressing
as indicated in the chart in annex
SECTION
E
for selecting the most appropriate one (00 to 90).

11.2.2 EXTERNAL STORAGE BOILER
(only for models 1.12 - 1.24)
CONNECTING THE STORAGE BOILER SENSOR
The boiler can be electrically connected to an external storage boiler. A diagram of the hydraulic connection of the external storage
boiler is shown in annex
"SECTION" F
. Connect the DHW priority sensor NTC to terminals
5-6
on terminal block
M2
. The sensitive
element of the NTC sensor must be inserted in the special well located on the storage boiler. Make sure that the exchange capacity
of the storage boiler coil is appropriate for the power of the boiler. Adjust DHW temperature (+35°C...+60°C) by pressing
.
IMPORTANT: set parameter P03 = 05 as described in section 14.
ELECTRICAL CONNECTION TO 3-WAY VALVE MOTOR
The 3-way valve motor and relative wiring harness are supplied separately in the form of a kit. Connect the plugs on the 3-way
valve wiring harness to terminals
8-9-10
of the
M2
terminal block on the boiler.
11.2.3 CONNECTING TO A ZONE SYSTEM
To use this function, install the programmable relay electronic board supplied as an accessory.

Room thermostat
The boiler can manage a zone heating system. The Room Unit (wall-mounted) can be used to control one zone while normal
ambient thermostats can be used to control the other zones.
SYSTEM CONNECTIONS
•
Connect the zone 1 valve/pump to terminals 1 - 3 of the relay board terminal block inside the boiler control box.
•
Connect the Ambient Thermostat contact of the other zones to terminals 1-2 of terminal block M1 (CONNECTING THE
AMBIENT THERMOSTAT section).
Check that parameter
