The terminal board on the fan 

coilis designed for connection 

to thevarious controls following 

the instructions provided in the 

section “Controls and Electrical 

Wiring Diagrams”.

All controls for installation on 

the unit are provided with a 

terminal board with plugs for 

rapid connection. Connect this 

terminal board to the corre-

sponding board on the side 

panel, then tighten the screws 

on the individual terminals to 

guarantee correct electrical 

contact. Failure to follow this 

instruction could cause serious 

risks.

The fan coils have a screw ter-

minal board in which the male 

terminal board of the control 

unit to be mounted on the unit 

is inserted or to which the wires 

from the remote control unit are 

connected.

Only one fan coil can be con-

nected to the control unit. To 

control more than one fan coil 

with a single control unit, each 

appliance must be fitted with 

an SEL speed selector which 

controls that particular unit 

according to the signal received 

from the centralised remote 

control unit.

The fan coil comes equipped 

with a fan that has a 6 speed 

motor, of which only 3 are con-

nected to the terminal board. 

Motor speeds are obtained 

through an auto-transformer. 

If wanting to make changes to 

the speed on the spot, it is suf-

ficient to move the speed cable 

connections (red, orange and 

black), that are connected to 

the auto-transformer, following 

the numbering in the diagram. 

The no. 6 connection on the 

auto-transformer corresponds 

to speed 1 from the table 

included in the sales catalogue. 

All other speeds follow the 

same connection logic.

Клеммная колодка на фанкойле 

предназначена для подключения 

к различным элементам 

управления в соответствии с 

инструкциям, приведенных в 

разделе “Органы управления и 

электропроводка, диаграммы”.

Все элементы управления 

для установки находятся 

на блоке платы с разъемами 

для быстрого соединения. 

Подключите этот разъем к 

соответствующим контактам 

на стороне панели платы, 

затем затяните винты на 

отдельных терминалах, чтобы 

гарантировать исправность 

электрического контакта, не 

соблюдение этого требования 

может привести к серьезным 

рискам..

У фанкойла есть винтовые 

клеммы, в которых клеммные 

колодки блока управления 

и провода от пульта 

дистанционного управления 

установлен на устройстве и 

они связаны между собой.

Только один фанкойл может 

быть подключен к блоку 

управления. Для управления 

более одного фанкойла с 

одного блока управления, 

каждый прибор должен 

быть оснащен селектором 

SEL , который управляет 

этой конкретной единицы в 

соответствии с сигналами 

от централизованного пульта 

дистанционного управления.

Фанкойл оснащен вентилято -

ром, который имеет 6 

скоростей двигателя, из 

которых только 3 подключены 

к клеммной колодке. Скоростя 

производятся с помощью 

автотрансформатора. Если 

нужно внести изменения в 

скорости на месте, достаточно 

переместить подключения 

кабелей (красный, оранжевый и 

черный), которые подключены 

к автотрансформатору, следуя 

нумерации на схеме. 

Подключение на 

автотрансформатор 

соответствует скорости 1 из 

таблицы включены в каталоге 

продаж. Все остальные 

скоростя следовать той же 

логике соединения.
