DESCRIPTION
OJ GreenZone™ Module MP-Bus controls VAV damper, temperature, CO2 and air hu-
midity in the room depending on which sensors are connected to the OJ GreenZone™
Module MP-Bus.
OJ GreenZone™ Module MP-Bus is self-configuring. This means that the controller
performs a test of the connected units and then controls the zone optimally on the
basis of the connected components, sensors, actuators, etc. once installation has been
completed and the OJ GreenZone™ Module MP-Bus is powered up.
The module is set and operated via the built-in web server, which is accessed via the
connected OJ GreenZone™ Master. Up to twenty-five OJ GreenZone™ Module units
can be connected to each OJ GreenZone™ Master. OJ GreenZone™ Module MP-Bus
is equipped with four MP-Bus connectors for valve and damper motors. The motors can
be freely distributed among the connectors.

INSTALLATION
OJ GreenZone™ Module MP-Bus should be fitted to a standard 35 mm DIN rail mount-
ed in an enclosure corresponding to the installation site classification (see fig. 2 for unit
dimensions). The unit itself is classed as IP20 and ETT-KH from OJ Electronics can be
used for such covering purposes. The most practical location will often be in the vicinity
of other components, valves, sensors, etc. associated with the VAV zone. An overview
of the physical configuration of the system is given in fig. 19.
An ideal location would be above a suspended ceiling panel. OJ GreenZone™ Module
MP-Bus must be provided with a 24 VAC, +/-15% power supply and is therefore
equipped with looping terminals (max. 1.5 mm
2
) for the purpose (see figs 8 and 9).
Other connections are made by means of a combination of RJ12 connectors and screw
terminals for connecting wires of max. 1.5 mm
2
cross-sectional area (see fig. 3).
Connections and indications (see overview in fig. 1)
In fig. 3, all connectors are marked with a letter (A – P).
See below for descriptions of electrical connection of the various components, inputs
and outputs, and other signals and indications of the OJ GreenZone™ Module MP-Bus.

Connectors "A-D" – MP-Bus actuators (see figs 3, 14, 14A, 16 & 16A)
MP-Bus actuators are connected by means of screw terminals. MP-Bus actuators and
VAV damper motors can be connected and freely distributed among the four MP-Bus
connectors. The maximum distance between OJ GreenZone™ Module MP-Bus and the
actuators is 30 m. All actuators must be put into to one of the MP-bus addresses in the
above table. All actuators must have dierent addresses. Address 4 and 5 cannot be
used together with address 6 or 7.
MP-Bus address and communication parameters are set in Belimo actuators using the
Service-Tool ZTH-EU programming unit from Belimo. Instructions for setting MP-Bus
addresses in Belimo actuators can be found at www.belimo.eu
MP-Bus VAV Dampers
OJ GreenZone™ Module MP-Bus can control three VAV dampers: one VAV damper in
the extract duct and two VAV damper in the supply duct. Supply VAV damper must have
MP-Bus address 2 and 3. Extract VAV damper must have MP-Bus address 1.
MP-Bus valve motors for heating and cooling systems
OJ GreenZone™ Module MP-Bus can control two MP-Bus valve motors: one valve mo-
tor for a heating element and one valve motor for a cooling element, both located in the
inlet duct. Alternatively it can control either a combination valve motor (heating/cooling)
or a 6 way valve motor. The heating valve must have MP-Bus address 4 and the cooling
valve must have address 5. The combination valve must have MP-bus address 6 and
the 6 way valve address 7.
Connection of temperature sensor in inlet duct (see figs 3 & 15)
It is possible to connect a sensor located in the inlet duct. The actual value recorded by
the sensor is shown on the zone's webpage. The temperature is used to control inlet
temperature.

Software update in progress
Connector “H” – Modbus sensor (°C, %rh or VOC) (see figs 3 and 18)
OJ GreenZone™ Module MP-Bus is equipped with a Modbus input for connecting
Modbus sensors (figs 3 and 18).
It is possible to connect a sensor of the following type from OJ Electronics:
• OJ-RPT-20T Room control panel with built-in temperature sensor
• TTH-6202 Duct temperature sensor
• TTH-6040-W Room temperature sensor
• VTH-6202 (VOC sensor)
• HTH-6202 (combined temperature and humidity sensor)
In larger rooms where you want to measure the temperature in several places, the
maximum number that can be mounted is 1 x OJ-RPT-20T, 1 x TTH-6040-W with the
dial in position 1, and 1 x TTH-6040-W with the dial in position 2. The Zone Module
calculates and uses the average temperature automatically from these sensors. The
terminal layout of the RJ12 connector is shown in fig. 6.
Connector “J” – “Modbus in” entry port (see figs 3 and 5)
OJ GreenZone™ Module MP-Bus is equipped with a “Modbus in” (see figs 3 and 5)
and a “Modbus out” (see figs 3 and 13) RJ12 connector for integration in the zone-
control system with a standard Modbus RJ12 cable (see fig. 4). The terminal layout of
the RJ12 Modbus connector is shown in fig. 6. The max. permissible distance between
two successive OJ GreenZone™ Module units is 100 m. The max. permissible total
cascade length of Modbus cable between all OJ GreenZone™ Module units is 2500 m.
The Modbus cable must be as shown in fig. 7. Modbus communication is OK when the
yellow LED flashes regularly.
Connector “K” – Voltage supply (see figs 8 and 9)
OJ GreenZone™ Module MP-Bus must be equipped with a 24 VAC power supply (see
figs 8 and 9). The 24 VAC connector is equipped with looping terminals to allow looping
to max. two other OJ GreenZone™ Module MP-Bus units.
The exit terminals (terminals 3 and 4) are short-circuit protected. This means that the OJ
GreenZone™ Module MP-Bus will continue to function even if the exit terminals (3 and
4) are short-circuited. It will therefore only be the subsequent OJ GreenZone™ Module
units that fail and become disconnected if terminals 3 and 4 are short-circuited.
English OJ GreenZone™ Module MP-Bus

© 2019 OJ Electronics A/S
The recommended cross-sectional wire area is 2x1.5 mm
2
. Modbus communication is
OK when the green LED flashes regularly.
NOTE!
The short-circuit protection means there is a limit to the load that can be placed on the exit
terminals (3 and 4). As a result, no more than two OJ GreenZone™ Module units may be
connected to exit terminals 3 and 4 (see fig. 9).
Connector “L” – PT1000 temperature sensor, humidity sensor and CO2 sensor (see
figs 3, 10 and 10A)
OJ GreenZone™ Module MP-Bus is equipped with inputs for analogue sensors (see figs
3, 10 and 10A). The inputs allow connection of a standard PT1000 sensor and a CO2
sensor with a standard 0-10 VDC output signal = 0-2000 ppm.
The sensors should be connected to the RJ12 connector marked “L” in fig. 3.
Note: This connector is NOT a Modbus connector.
Room temperature
sensor: The PT1000 room temperature sensor can be installed in the
exhaust duct or the room. It connects to screw terminal 9 and
10. (See fig. 10).
0-10 VDC input
for CO2 sensor: The CO2 sensor can be installed in the exhaust duct or in the
room. It should be connected to pins 5, 6 and 8 (see fig. 10).
0-10 VDC input
for humidity sensor: The humidity sensor can be installed in the exhaust duct or in
the room itself. It should be connected to screw terminals 6, 7
and 8 (see fig. 10A).
If no Modbus temperature sensor is connected to the connector marked “H”, the
PT1000 sensor connected to this input (“L”) will automatically be configured as an
exhaust/room sensor.
If a Modbus sensor is connected to the connector marked “H”, the Modbus sensor
values have higher priority than that of the humidity sensor on terminal 7 and the
temperature sensor on terminal 10.
Connector “M” – Temperature oset (°C) (see figs 3 and 11)
OJ GreenZone™ Module MP-Bus is equipped with an inlet for the connection of a
control unit for user-determined oset in room temperature (see figs 3 and 11). Via the
web user-interface, the temperature oset can be set to either +/-3 °C or +/-5 °C.
OJ GreenZone™ Module MP-Bus English
10
© 2019 OJ Electronics A/S
The temperature oset potentiometer ETFWP-998 from OJ Electronics has both
PT-1000 room sensor and potentiometer.
NOTE!
If an alternative potentiometer is used, the potentiometer resistance must be
min. 4.7 kΩ and max. 22 kΩ.
Connector “N” – Window contact, frostalarm and PIR sensor (see fig. 3)
OJ GreenZone™ Module MP-Bus is equipped with digital inputs for the connection of
window contact, frost thermostat and PIR sensor. On the overview diagram (fig. 3), the
input terminals are marked “N”.
Frost thermostat
The frost thermostat should be attached physically to the heating element. Suitable
thermostats are Danfoss type KP61, Thermokon type TFR or TFR-R, or similar ther-
mostat with bulb or capillary tube. The bulb or capillary tube should be attached to the
heating element in the air flow on the hot side of the element. If the frost thermostat is
activated (digital input opens), the installed heating valve will be forced to open 100 %.
The frost thermostat should be connected electrically as shown in fig. 12. The NC
contact of the frost thermostat should be used so that the input is active when there is
no danger of frost. The input is factory-equipped with a jumper.
Window contact
The window contact should be physically attached to the window or windows to be
monitored. If several windows are to be monitored, the window contacts should be con-
nected in series. If the windows are opened (the window contact is opened), the heating
and cooling valves will be forcibly closed. The VAV damper can be set to close.
The window contact(s) should be electrically connected as shown in fig. 20. The NO
contact of the window contact(s) should be used so that the input is active when the
window(s) is(are) closed. The input is factory-equipped with a jumper.
PIR sensor/motion detector
The PIR sensor should be positioned in the area of the room where motion is to be
detected. If several PIR sensors are to be used, they should be connected in parallel. If
the PIR sensor(s) detect motion in the room, the zone will be activated and controlled in
accordance with the set operating parameters.
The PIR sensor(s) should be electrically connected as shown in fig. 21.
The NO contact of the PIR sensor(s) should be used so that the input is active when
motion is detected in the room.

ALLGEMEINES
Das OJ GreenZone™ Module MP-Bus ist eine elektronische Steuerung (Regler) für VVS-
Zonen in Lüftungsanlagen. Das OJ GreenZone™ Module MP-Bus umfasst alle die Funkti-
onen, die zur energie- und komfortoptimalen Steuerung einer VVS-Zone erforderlich sind.
BESCHREIBUNG
Das OJ GreenZone™ Module MP-Bus steuert VVS-Klappen, Temperatur, CO2 und Luft-
feuchtigkeit im Raum, abhängig davon, welche Fühler an die Einheit angeschlossen sind.
Das OJ GreenZone™ Module MP-Bus ist selbst konfigurierend. Dazu führt die Steue-
rung einen Test der angeschlossenen Einheiten durch und regelt nach Abschluss der
Installation und Aktivierung des OJ GreenZone™ Module MP-Bus auf Basis der ange-
schlossenen Komponenten, Fühler, Stellantriebe u. a. m. die Zone optimal.
Einstellungen und Bedienung erfolgt über den integrierten Webserver; der Zugri auf
den Webserver erfolgt über den angeschlossenen OJ GreenZone™ Master.
An jeden OJ GreenZone™ Master können max. 25 Stk. OJ GreenZone™ Modules an-
geschlossen werden. OJ GreenZone™. Modul MP-Bus ist mit vier MP-Bus anschlüsse
für Ventil- und Klappenmotoren ausgestattet. Die Motoren können frei zwischen den
Anschlüssen verteilt werden.

INSTALLATION
Das OJ GreenZone™ Module MP-Bus ist in einem der Klassifikation des Installations-
orts entsprechendem Gehäuse auf einer standardmäßigen 35 mm DIN-Schiene zu
installieren (siehe Abmessungen in Abb. 2). Schutzart ist IP20; ETT-KH von OJ Elect-
ronics ist als Abdeckung dafür geeignet. Geeignetster Standort ist in der Regel in der
Nähe der in der VVS-Zone angeschlossen Komponenten, Ventile, Fühler u. a. m. Für die
physische Konfiguration siehe Abb. 19.
Eine optimale Platzierung wäre z. B. im Zwischenraum über einer abgehängten Decke.
Das OJ GreenZone™ Module MP-Bus ist mit 24 V~ ±15% zu versorgen, und deshalb
zu diesem Zweck mit Schleifenklemmen (max. 1,5 mm²) ausgestattet (siehe Abb. 8 und
9). Die übrigen Anschlüsse sind eine Kombination von RJ12-Steckverbindungen und
Schraubklemmen für Leiter mit max. 1,5mm² (siehe Abb. 3).
Anschlüsse und Kennzeichnungen (siehe Abb. 1 und 3)
In Abb. 3 sind alle Anschlüsse mit einem Buchstaben (A-P) gekennzeichnet.
Siehe folgenden Beschreibung der elektrischen Anschlüsse für jede einzelne Kompo-
nente, Ein-und Ausgänge und andere Signale und Kennzeichnungen am OJ GreenZo-
ne™ Module MP-Bus.

Anschlüsse „A-D“ – MP-Bus-Stellantriebe (siehe Abb. 3, 14, 14A, 16 und 16A)
MP-Bus-Stellantriebe sind über Schraubklemmen angeschlossen. MP-Bus-Stellantriebe
und VVS-Klappenmotoren können beliebig auf die vier MP-Bus-Anschlüsse verteilt
angeschlossen werden. Der Abstand zwischen OJ GreenZone™ Module MP-Bus und
den Stellantrieben darf maximal 30 m betragen. Alle Stellantriebe müssen auf eine der
in der obigen Tabelle aufgeführten MP-Bus-Adresse eingestellt sein. Jeder Stellantrieb
muss eine andere Adresse haben. Die Adressen 4 und 5 können nicht zusammen mit
den Adressen 6 und 7 verwendet werden.
Die Einstellung von MP-Bus-Adresse und Kommunikationsparameter in Belimo-
Stellantrieben erfolgt mit dem Servicetool ZTH-EU-Programmiergerät von Belimo. Eine
Anleitung zur Einstellung der MP-Bus-Adresse in Belimo-Stellgliedern findet sich auf
www.belimo.eu.
MP-Bus VVS-Klappen
OJ GreenZone™ Module MP-Bus kann drei VVS-Klappen steuern: eine VVS-Klappe
im Abluftkanal und zwei VVS-Klappen im Zuluftkanal. Die Zuluft-VVS-Klappe muss die
MP-Bus-Adresse 2 und 3 haben. Die Abluft-VVS-Klappe muss die MP-Bus-Adresse
1haben.
MP-Bus-Ventilmotoren für Heiz- und Kühlanlagen
OJ GreenZone™ Module MP-Bus kann zwei MP-Bus-Ventilmotoren steuern: einen
Ventilmotor für ein Heizelement und einen Ventilmotor für ein Kühlelement, beide im
Zuluftkanal platziert. Alternativ kann er auch entweder einen Kombiventilmotor
(Heizen/Kühlen) oder einen 6-Wege-Ventilmotor steuern. Das Heizventil muss die
MP-Bus-Adresse 4, das Kühlventil die Adresse 5 haben. Das Kombiventil muss
die MP-Bus-Adresse 6, das 6-Wege-Ventil die Adresse 7 haben.
