9. ACCESSORIES NOT INCLUDED IN THE PACKAGING
9.1 WIRING OF BOILER PUMP
Connect the boiler pump to terminals
1-2
of the
M3
terminal block as described in section 8. If the pump is a modulating pump
connect the
PWM
signal to the termials
5-6
of the
M3
terminal block.
9.2 HEATING SYSTEM PUMP
Install the system pump downline from the hydraulic separator. Choose the pump according to the required system capacity/head
characteristics (see chap.
"BOILER PUMP"
).
A 250Vac/250Vac relay with a minimum current rating of 16A and able to withstand a starting current of above 100A is
required to connect the external pumps.
9.3 DOMESTIC HOT WATER CYLINDER
The boiler can be electrically connected to an external storage tank. A diagram of the hydraulic connection of the external storage
tank is shown in chap.
"DIAGRAMS"
. Connect the storage tank pump to terminals
9-10
of the
M3
terminal block (see chap.
"ELECTRICAL CONNECTIONS"
). Install the storage boiler downline from the hydraulic separator. Use the sensor supplied as
an accessory and connect it to terminals
9-10
of terminal block
M2
(see chap.
"ELECTRICAL CONNECTIONS"
). Make sure that
the exchange capacity of the domestic hot water coil is appropriate for the power of the boiler.
A 250Vac/250Vac relay with a minimum current rating of 16A and able to withstand a starting current of above 100A is
required to connect the external pumps.
The anti-legionellosis function is
NOT
ENABLED. To enable it, set parameter
1640
as described below.
To activate the ANTILEGIONELLOSIS function, proceed as follows:
•
Access MENU 2 as described in section 8.1.1.
•

Periodically
or
Fixed weekday
then choose one of the two items and
B
to confirm.
Choose
Periodically
to enable the function once a week on the set day and at the set time. To set the day and time, use the same
procedure described above: set parameter
1641
to establish which days (from 1 to 7) the function must activate and parameter
1644
to set the starting time of the function.
Choose
Fixed weekday
to enable the function once a week on the set day and at the set time. Set parameter
1642
to establish
the day of the week (from Monday to Sunday) on which the function must activate and parameter
1644
to set the start time of the
function.
9.4 MIXED ZONES (see chap. "DIAGRAMS")
A mixed zone can be managed using the
AVS75
external module, supplied as an accessory. This accessory can manage: a zone
pump, a mixing valve, a temperature sensor, a limit thermostat and a room thermostat. To connect the components and adjust the
system read the manual provided with the accessory.
9.5 OUTDOOR SYSTEM MANAGEMENT MODULES
The boiler can independently manage up to three heating circuits by using external accessories such as room units, remote
controls and external modules (AVS 75.391 and AVS 75.370). The boiler electronics also comprises a wide range of functions for
personalising and managing various system types. To assure correct system operation, a number (from 1 to 3) must be assigned
to each accessory in order to allow the boiler board to recognise it. Consequently, carefully read the instructions provided with the
accessories. The external module AVS 75.370 can be used to control modulation of 2 pumps: a zone pump and/or the storage
boiler pump.
9.6 BOILERS IN A CASCADE CONNECTION (see chap. "DIAGRAMS")
The
AVS75
external unit, supplied as an accessory, is used to manage a heating system with up to 16 boilers connected in a
cascade arrangement and a possible separate storage tank providing domestic hot water. This accessory, connected to one of
the cascade boilers, can directly control the circuit components up to a maximum of 3 independent relay outlets, 2 temperature
sensors, 1 high voltage limit thermostat connector and one 1 control input (e.g.: room thermostat). The system also requires an
OCI 345
interface on each boiler comprising in the cascade arrangement.
THE HYDRAULIC DIAGRAMS OF THE CASES DESCRIBED CAN BE FOUND IN CHAP. "DIAGRAMS".
9.7 AGU 2.550
Use the
AGU 2.550
, already installed in the boiler, to send information from the
boiler as described below to a BMS panel.
