1. Summary
This manual provides you with detailed technical information on the 10A Series FCU Actuator, including installation and
programming details, and explains how to use the 10A Series FCU Actuator based on practical examples. For easy
installation into distribution boxes, the 10A Series FCU Actuator Modules are designed as modular mounting devices
that can be mounted on 35mm DIN rails.
10A series FCU is used to control fan coil units, such as air conditioners, etc., with magnetic hold function.
Installed as a system with other loads via EIB/KNX bus.
The entire system is set up and operated using the engineering design tool software ETS.
2. Product and Feature Overview
The 10A Series FCU actuator are modular installation devices. Connect to the EIB / KNX system through the EIB bus
terminal block, and use the engineering design tool software ETS software (version ETS4.0 or later) to assign physical
addresses and set parameters.
The maximum load current output by each 10A series FCU actuator is 10A, especially when multiple fans are connected
in parallel, the load that can be carried will be reduced. Although the power remains unchanged, the instantaneous
inrush current will increase, which is easy to cause the relay contacts are melted, so it is advisable to use 1/5 or 1/6 of the
maximum current.
The fan coil execution module has manual control buttons, and the LED lights on the buttons indicate the on/off status
of each circuit; the fan coil execution module has 4 dry contact input interfaces, which can input switches, curtains,
dimming, scenes, etc. Control instruction.
Function description:

(7) Selection function of relay switch state after bus power failure and voltage recovery;
(8) The local wind speed and valve status can be reported;
(9) The 10A FCU actuator has an I/O contact input interface, which can input control commands such as switches,
curtains, dimming, and scenes; it can directly link fire emergency lighting;

6. Parameter setting and communication object description
6.1 Switch setting function parameters
The following takes ETS5 as an example to set parameters in ETS5 Note: In the following introduction, Channel X or
X represents the output of the corresponding channel.
1) Open the parameter setting interface of the 10A series FCU actuator in ETS5, as shown in Figure 6.1.1. The
parameter "Channel X" represents the output of the corresponding channel. The parameter "Field control"

represents the field control function. When the "off" command is sent, the relay state of each channel is saved and
turned off. When the "on" command is sent, the last saved relay state is called. (Note: The "off" command cannot be
sent twice in a row, because the current state is saved when the "off" command is sent for the first time, but the first
send is saved when the "off" command is sent for the second time" off” command, overwriting the state of the
scene saved for the first time).
Optional: Disable & Enable
When selecting the first fan, select "Enabled" in Channel 1—Channel 5, and select "Disabled" for other items; when
selecting the second fan, select "Enabled" in Channel 6—Channel 10, and select "Disabled" for other items.
"Disabled"; if you select 2 channels of fans at the same time, select "Enabled" in Channel 1—Channel 10, and select
"Disabled" in other items. In addition, the 10A fan coil execution module has 4 dry contact input interfaces. (Here,
take the selection of the fan coil execution module with 1 fan as an example)
