ZONE SYSTEM WITH INSTALLATION OF THE REMOTE CONTROL
The electrical connection and the adjustments required to manage a system divided into zones with use of the Remote Control
Module supplied as an accessory.
ADJUSTING THE TEMPERATURE OF THE HIGH TEMPERATURE HEATING SYSTEM
To avoid frequent starting and stopping, raise the minimum temperature setpoint of the boiler in the heating mode by setting
parameters 740
TEMPERATURE ADJUSTMENT ON LOW TEMPERATURE HEATING SYSTEM
parameter 741
11.2.2 EXTERNAL SENSOR
and the instructions supplied with the sensor.
With the External Sensor connected,
control panel move the set climate curve Kt in parallel (see
annex "SECTION" E and parameter P03 in the table in section
14). To increase room temperature press +, to decrease press -.
SETTING THE "Kt" CLIMATE CURVE
To set the required kt climate curve, proceed as follows:
Access the menu as described in section 14.
Select parameter P03.
Select the climate curve from among those available, see the curve chart in annex "SECTION" E at the end of this manual
(the preset curve is 1.5).

11.2.3 HEATING SYSTEM PUMP
Install the system pump downline from the hydraulic separator. Choose the pump according to the required system capacity/head
characteristics (see annex "SECTION" F).
11.2.4 EXTERNAL STORAGE BOILER
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 storage boiler pump to terminals 4-5 of the M3 terminal block (see annex
"SECTION" B). 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 annex "SECTION" B). Make sure that the exchange capacity of the storage
boiler coil is appropriate for the power of the boiler.

EXTERNAL 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 (AGU 2.550 and AVS 75). 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.
11.2.5 MIXED ZONES ("SECTION" F)
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.
11.2.6 BOILERS IN A CASCADE CONNECTION ("SECTION" F)
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 boiler 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. To adjust boiler parameters see section "PARAMETER
SETTINGS". To connect the components and adjust the system read the manual provided with the accessory.
