Chapter 2 Introduction to Regio Maxi
Regio zone controllers
Regio is a wide series of room controllers which handle everything from heating, cooling and
ventilation to lighting, humidity, CO2monitoring and blinds. Regio can be used for creating
everything from stand-alone systems for managing the functions in one room, to large,
integrated systems with a comprehensive SCADA-system.
Regio also offers web and Internet solutions. Temperature and other functions in a room can
be individually controlled from a PC connected to the office network.
Mini, Midi, Maxi The Regio controllers are divided into three different series, Mini, Midi and Maxi.
Mini (RC) are 24 V AC stand-alone controllers for controlling heating and cooling in a
room. The series consists of different room control units and a relay box for fan control. The
control units are pre-programmed to handle different functions and can easily be configured.
They have a built-in temperature sensor, but an external temperature sensor can also be
connected.
The Midi controllers (RC-C) have the same characteristics as Mini. They can be used stand-
alone or in a system with communication. The controllers are connected to bus lines such as
Modbus or Regin’s own bus system EXOline, to communicate with a central SCADA-
system via RS485. They can also be configured for a specific application with Regin’s
software tool Regio tool©.
Maxi (RCP) are 230 V AC freely programmable room controllers for handling all functions
in a zone system. The controllers are pre-programmed but can be configured using Regio
tool©. Different room units (RU-units) with built-in temperature sensor are connected to the
controllers. Maxi can be connected to standardised bus systems like Modbus or EXOline,
with communication via TCP/IP, RS485 or LON, and integrated with a central SCADA-
system. Using EXO4 Web Server, all functions can be handled from a PC with Internet
Explorer and no room units are needed. This will keep the investment down.
Awarded design Regio has a modern design which enhances the indoor environment. The design has been
awarded the 2007 “iF product design award”, which more than 1100 participants from over
30 countries compete for every year. The contributions are judged by an international panel,
according to a large number of criteria. The competition has been running for 53 years and is
one of the most acknowledged design competitions in the world.
Applications The Regio controllers have appealing design and functionality. They are suitable in buildings
where you want optimal comfort and low energy consumption, for example offices, schools,
shopping centres, airports, hotels and hospitals.
Mounting The modular design with a separate bottom plate for wiring makes the whole Regio series
easy to install and commission.

8 Part I Introduction
Regio Maxi
Communication The Maxi controllers (RCP-controllers) can be connected to a central SCADA-system via
RS485 (EXOline or Modbus), TCP/IP or LON and configured for a particular application
using the configuration tool Regio tool©, which can be downloaded free of charge from
Regin’s homepage www.regin.se. See the manual for Regio tool©for more information.
LON communication Models with LON communication use LonWorks, adjusted according to the LonMark
guidelines. See the LonWorks network variable list in chapter 20.
LON communicates via the LON port on the RCP-unit. The configuration takes place on the
display of the RU-unit or via Regio tool©on a PC connected via the RS485 port on the RCP-
unit. The RCP-unit should be installed in the LON network with the help of LonMaker or a
corresponding computer program.
Control states The controllers can be configured for different control states/control sequences:
Heating
Heating or cooling via the change-over function
Heating/Heating
Heating/Cooling
Heating/Cooling with VAV-control and forced supply air function
Heating/Cooling with VAV-control
Cooling
Cooling/Cooling
All RCP-models can be used for controlling thermal actuators and three-point actuators. The
RCP200...-models can also control 0...10 V actuators, and the RCP...F…-models can be used
for fan coil control.

RU-units
There are 7 different room units in the Maxi series. They can be divided according to type of
control into basic models, models for fan control and a flexible model with special functions
(RU-DOS). For information on how the RU-units can be combined with the RCP-controllers,
see table 1 on page 9.
Basic models Basic models can be used in installations with 0...10 V actuators, thermal actuators or
three-point actuators.
RU-F-models RU-models for fan control (RU-F-models) can be used for the same applications as the basic
models. They also have a fan button/switch for controlling a three-speed fan (fan coil, etc.).
RU-DOS RU-DOS can be used for the same applications as the basic models and the RU-F-models. It
also has special functions like lighting control, CO2-control, control of blinds, display of
humidity and outdoor temperature. Read more in the chapter Functions with RU-DOS.

Chapter 5 Installation preparations
Using labels
On the back of the units’ electronics cassette, there is a set of labels which makes it easier to
install large numbers of Maxi controllers. By using the labels as carriers of information for
the installation engineer, much time will be saved and you can keep wiring errors at a
minimum.
Figure 1. Label on the back of the RCP-controller
Figure 2. Label on the back of the RU-unit
The three-piece label can be split and the parts can be fastened to the installation drawing
and the bottom plate of the controller. The label carries information on the communication
address etc., and has a note area where you can enter a reference number to the connection
diagram.
If you want to configure the RCP, it may be better to do this before sending the cassette to
the installation site. For more information about configuration, see the chapter
Configuration.
The bottom plates with location and wiring information can be sent separately to the
installation site for electric installation.
Configuration
The RCP-controllers are configured using Regio tool©. For more information, see the manual
for Regio tool©. Some settings may also have to be made in the RU-unit. RU-models without
display have dipswitches that should be set, see the section Dipswitches below.
The computer with Regio tool©is connected to the bottom plate using E-cable. E-cable is
connected to terminal 41(A) & 40(B). 230 V AC is connected to L1 and N3.

Setting the dipswitches in RU (only models without display)
RU-models without display have four dipswitches (SW1-4) for setting basic functions. They
are found on the back of the electronics cassette.

SW3 Occupied is the preset operating mode, SW3: OFF (FS). If you want the preset operating
mode to be Stand-by, set SW3 in mode ON. For more information, see the chapter Operating
modes.
SW4 Not used.
RU-models with display
There are no dipswitches in RU-models with display. For these models, the corresponding
settings are made in the parameter menu in the display or using Regio tool©, see the chapter
Display handling.

20 Part II Installation
Chapter 6 Installation
Installation should be done by a professional installer. Since the RCP-unit is powered by 230
V AC, it must be handled with great care. Always switch the power off before removing the
cover and electronics cassette from the bottom plate.
Mounting
Mounting of RU
Place the controller in a location that has a temperature representative for the room. A
suitable location is approx. 1.6 m above floor level in a place with unobstructed air
circulation. Remove the frame by depressing the locking tab in the lower edge of the cover
with a screwdriver. See figure 4.
Then prize out the electronics cassette using the four rectangular screwdriver slots and
levering against the edge of the bottom plate. See figure 5. Note: Take care not to damage
the electronics when inserting the screwdriver into the slots.
Figure 4. Figure 5.
The bottom plate with terminals has a number of fixing hole combinations. Select suitable
holes and screw the bottom plate onto the wall or connection box, so that the arrows on the
bottom plate point upwards. Do not tighten the screws too hard!
With surface-mounted cabling, break out suitable holes from the marks in the plastic.
