THANK YOU FOR CHOOSING REGIN!
Ever since Regin was established in 1947, we have developed and mar eted products and systems that create good
levels of indoor comfort. Today, we are an important player with one of the mar et's broadest ranges for building
automation.
Our goal is to ma e real estates in the world more energy efficient. Regin is an international group and our products
sells in over 90 countries. Than s to our global presence with strong local representation, we are well aware of the
requirements of the mar et, as well as of how our products and systems function under the most variable conditions.
Every year, Regin ma es substantial investments in the development of our systems and HVAC-products.

Introduction
1 Introduction
1.1 General
The Add:io series is intended for use in combination with EXOclever and EXOcompact to expand the
number of I/Os in a system. Each unit expands the system with 16 I/Os. An EXOclever controller can be
expanded with unlimited I/Os and an EXOcompact with up to 50 I/Os.
The units are programmable in EXOdesigner, the same environment used for all other EXO controllers.
1.2 Layout
All available Add:io models have a similar design and layout. It is shown in Figure 1-1.

1.4 Mounting
The controllers are designed to be mounted on a DIN-rail. They can be mounted in two ways, either on their
bac side or stac ed on the short side with a high pac ing density as a result. When stac ed they fit smoothly
together thus requiring minimal space (see Figure 1-2)

Introduction
1.5 Communication
The EFX-port is the communication channel used between the Add:io and a master controller (e.g.
EXOclever). EFX is RS485-based communication.
1.6 Naming
All Add:io models are named the following way:
IO-ECzzyyy-X IO-EC = Add:io family naming
zz = Number of IOs
yyy = IO-type, e.g. UId
-X = EFX communication

2.1 In tallation recommendation
Follow these guidelines regarding shielded cables:
✓Only use shielded cables when the installation environment requires it.
✓No need for shielded cables between modules, if installed in close proximity
✓Connect shield to chassis ground at only one end of the cable.
For RS485 communication, the terminal Nis only required between systems not sharing the same ground
potential. When used, do not connect it to the cable screen. Note that it may be a single wire, but must be
drawn together.
When the cable length is less than 30 m in RS485, a terminator is not required in normal cases. The use of
terminators will decrease signal integrity thus try without first. When used, match the terminator value to
the characteristic impedance of the cable.
NNoottee!! Do not mix and u e one GND for everal input .
The technical earth terminal in the IO module power connector i not intended a a connection for
cable creen .
When connecting and measuring an external transmitter in an UI port this is done between terminals UIx
and GNDx (where x is the channel number between 1…16). Note that the intention is to use the
corresponding GND for the connected UI, especially when measuring sensitive signals or using DI pulse
(fast) mode.
Wiring examples can be found under each specific Add:io model in the following chapters.
2.2 General tatu indicator
The Add:io has a general status indicator mounted at the middle right front side, see Figure 1-1, which can be
inspected both when the unit is mounted on its bac and side. This indicator changes colour depending on its
actual status as shown in Table 2-1.
Table 2-1 Status indication at the front
LED status Controller status
Green, solid Power on and communication is established
Red, solid Battery problem
Yellow, blink 2.5 Hz Identification (wink)
Orange, blink 1 Hz IO-board is not in contact with CPU-board (via EFX)
The status indications that are present on the side, see Figure 1-1, are only active when the universal inputs or
outputs are configured as DI and DO. The indicator colours are shown in Table 2-2.

2.3 Sy tem addre ing
The module has to be given an address between 0-255 in order to be able to communicate with it in a
system. The address is set with the 8-bit DIP-switch mar ed with Module Address on the Add:io unit. The
least significant bit (LSB) is mar ed Bit 1 and the most significant bit (MSB) is mar ed Bit 8.
A switch is activated by setting it to 1. In Figure 2-1 the address is set to 3.
