DESCRIPTION
OJ GreenZone™ Module A controls VAV damper, temperature, CO2 and air humidity in
the room depending on which sensors are connected to the OJ GreenZone™ Module A.
OJ GreenZone™ Module A 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 A 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 A units can be connected to each OJ Green-
Zone™ Master.
OJ GreenZone™ Module A Modbus is equipped with 4 x 0-10 VDC for valve and

INSTALLATION
OJ GreenZone™ Module A should be fitted to a standard 35 mm DIN rail mounted in an
enclosure corresponding to the installation site classification (see fig. 2 for unit dimen-
sions). 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
A must be provided with a 24 VAC, +/-15% power supply and is therefore equipped
with looping terminals (max. 1.5 mm2) for the purpose (see figs 8 and 9). Other connec-
tions are made by means of a combination of RJ12 connectors and screw terminals for
connecting wires of max. 1.5 mm2 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 A.

OJ GreenZone™ Module A can control two VAV dampers: one VAV damper in the
exhaust duct and one VAV damper in the inlet duct. The VAV damper motors are con-
trolled by means of a 0-10 V signal.
• The VAV damper motor in the zone's exhaust duct should be connected to terminals
18, 19 & 20 (see fig. 14)
• The VAV damper motor in the zone's inlet duct should be connected to terminals 21,
22 & 23 (see fig. 14A)
Connection of valve motors for heating and cooling systems (see figs 3, 16 & 16A)
OJ GreenZone™ Module A can control two 0-10 V valve motors: one valve motor for
any heating element located in the inlet duct and one valve motor for any cooling ele-
ment located in the inlet duct. The valve motors are controlled by a 0-10 V signal.

Connector “H” – Modbus sensor (°C, %rh or VOC) (see figs 3 and 18)
OJ GreenZone™ Module A 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.
OJ GreenZone™ Module A English / Instruction

Connector “J” – “Modbus in” entry port (see figs 3 and 5)
OJ GreenZone™ Module A 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 suc-
cessive OJ GreenZone™ Module A units is 100 m. The max. permissible total cascade
length of Modbus cable between all OJ GreenZone™ Module A units is 2500 m. The
Modbus cable must be as shown in fig. 7. Modbus communication is OK when the yel-
low LED flashes regularly.
Connector “K” – Voltage supply (see figs 8 and 9)
OJ GreenZone™ Module A 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 A units. The exit terminals (terminals 3 and 4) are short-
circuit protected.
This means that the OJ GreenZone™ Module A 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 A units that fail and become disconnected if terminals 3 and 4
are short-circuited. The recommended cross-sectional wire area is 2x1.5 mm2. 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 A 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 A 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 temp.
sensor: The PT1000 room temperature sensor can be placed in the exhaust
duct or in the room. It connects to screw terminal 9 and 10.
(Seefig. 10).
English / Instruction OJ GreenZone™ Module A

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 of the RJ12 connector
(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 temperature 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 oset (°C) (see figs 3 and 11)
OJ GreenZone™ Module A is equipped with an inlet for the connection of a control unit
for user-determined oset in room temperature (see figs 3 and 11). Via the web user-
interface, the temperature oset can be set to either +/-3 °C or +/-5 °C.
The temperature oset 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 A 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 %.
OJ GreenZone™ Module A English / Instruction
10
© 2017 OJ Electronics A/S
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.
Connector “P” – “Modbus out” exit port (see figs 3 and 13)
OJ GreenZone™ Module A 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 figs 4, 5 and 13). The terminal layout
of the RJ12 Modbus connector is shown in fig. 6. The Modbus cable must be as shown
in fig. 7. Modbus communication is OK when the green LED flashes regularly.
Addressing OJ GreenZone™ Module A
The OJ GreenZone™ Module A is addressed automatically by the OJ GreenZone™
Master to which it is connected.
The address is shown on the display of the OJ GreenZone™ Module A (see table 3 in
these instructions). Further information about addressing is found in the OJ Green-
Zone™ Master manual and in OJ Green Zone installer instructions.

BESCHREIBUNG
Das OJ GreenZone™ Module A steuert VVS-Klappen, Temperatur, CO2 und Luftfeuch-
tigkeit im Raum, abhängig davon, welche Fühler an die Einheit angeschlossen sind.
Das OJ GreenZone™ Module A ist selbst konfigurierend. Dazu führt die Steuerung
einen Test der angeschlossenen Einheiten durch und regelt nach Abschluss der Instal-
lation und Aktivierung des OJ GreenZone™ Module A auf Basis der angeschlossenen
Komponenten, Fühler, Stellglieder 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™ Module A
angeschlossen werden.
Das OJ Green Zone™ Modul A ist mit 4 × 0-10 V= für Ventil- und Schiebermotoren
ausgestattet.
