-
5
) and the instructions supplied with the sensor.
With the outdoor sensor connected, press
buttons on the control panel to move the set climate curve
Kt
in parallel (see
annex
“SECTION” F
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” F
at the end of this manual
(the preset curve is 1.5).

11.2.3 BOILER PUMP
Connect the boiler pump to terminals
1-2
of the
M3
terminal block as described in section 3. If the pump is a modulating pump
connect the
PWM
signal to the termials
5-6
of the
M3
terminal block.
11.2.4 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” E
).
11.2.5 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 annex
“SECTION” G
. Connect the storage tank pump to terminals
4-5
of the
M3
terminal block (see annex
“SEC-
TION” 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 domestic hot
water coil is appropriate for the power of the boiler.
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). 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.
11.2.6 MIXED ZONES (“SECTION” G)
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.
11.2.7 BOILERS IN A CASCADE CONNECTION (“SECTION” G)
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.
