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

damper motors.

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.

Connection of VAV damper motors (see ﬁgs 3, 14 & 14A)

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.

6

• The heating valve should be connected to terminals 24, 25 & 26 (see ﬁg. 16)

• The cooling valve should be connected to terminals 27, 28 & 29 (see ﬁg. 16A)

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.

NOTE! The sensor must be of PT1000 type.

• The sensor should be connected to terminals 30 & 31 (see ﬁg. 15).

Display “G” (see ﬁgs 3 and 17)

OJ GreenZone™ Module A is equipped with a 2-digit display (ﬁg. 3, pos. “G”).

The display indicates various things as shown in table 3 below.

The display alternates (ﬂashes) between the activated functions and readouts.

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

8

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.

(Seeﬁg. 10).

English / Instruction OJ GreenZone™ Module A

9

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 oset (°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 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.

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 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

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.
