INSTALLATION
OJ GreenZone™ Module M 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
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
M 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 mm2cross-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 M.
Connectors “A – B – C” – Modbus actuators (see figs 3 and 14)
Modbus actuators are connected by means of RJ12 connectors.
Up to three Modbus actuators can be connected and VAV damper motor, cooling valve
or heating valve may be freely chosen. The maximum distance between OJ Green-
Zone™ Module M and the actuators is 30 m. OJ GreenZone™ Module M can itself
ascertain which actuators are connected if each actuator has been programmed with a
Modbus address in accordance with the following table.

7. 6 way valve (heating/cooling) 7
Modbus address and communication parameters are set in Belimo actuators using
the Servicetool ZTH-EU programming unit from Belimo. The Modbus communication
protocol is 38.4 kBaud, 1 start bit, 8 data bits, 2 stop bits and no parity (see example
of ZTH-EU menu settings for VAV actuators in fig. 22). Instructions for setting Modbus
addresses in Belimo actuators can be found at www.belimo.eu.
LED indications “D” (see figs 3 and 15)
OJ GreenZone™ Module M is equipped with five LEDs, which indicate the status of the
Modbus actuators (see table 2).

Connectors “E – F” – Enabling signal, heating/cooling (see figs 3 and 16)
OJ GreenZone™ Module M is equipped with two potential-free digital outputs, which
are activated when the zone is in heating status or cooling status respectively.
• T
he output
(terminals 12-13) can be used to enable for example an electric heating
element in the room when the zone is in heating status (fig. 16).
• The output
(terminals 14-15) can be used to enable for example an external cooling
element in the room when the zone is in cooling status (fig. 16).
Important! Never apply dierent voltages to the two outputs. The voltage on the two out-
puts must be either 230 VAC on both outputs or 24 VAC on both outputs. Mixing voltage
levels on the two outputs may damage the product beyond repair.
Display “G” (see figs 3 and 17)
OJ GreenZone™ Module M 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.
Example:
If the OJ GreenZone™ Module M is configured as follows:
• Connected to OJ GreenZone™ Master 1
• Allocated zone 13 by OJ GreenZone™ Master
• A PT1000 temperature sensor is installed in the inlet duct
• A combined temperature/humidity sensor (HTH-6202) is installed in the exhaust duct
- the display will alternate between the following readouts:

Connector “H” – Modbus sensor (°C, %rh or VOC) (see figs 3 and 18)
OJ GreenZone™ Module M 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:
• VTH-6202 (VOC sensor)
• HTH-6202 (combined temperature and humidity sensor)
• TTH-6202 duct temperature sensor
• TTH-6040-W room temperature sensor
• OJ-RPT-20T room control panel with built-in temperature 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 M is equipped with a “Modbus in” (see figs 3 and 5) and a
English / Instruction OJ GreenZone™ Module M

“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 M units is 100 m. The max. permissible total cascade
length of Modbus cable between all OJ GreenZone™ Module M units is 2500 m. The
Modbus cable must be as shown in fig. 7. The green flashing LED indicates functional
Modbus communication.
Connector “K” – Voltage supply (see figs 8 and 9)
OJ GreenZone™ Module M 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 M units. The exit terminals (terminals 3 and 4) are short-
circuit protected.
This means that the OJ GreenZone™ Module M 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 M units that fail and become disconnected if terminals 3 and 4 are
short-circuited. The recommended cross-sectional wire area is 2x1.5 mm2.
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 M units may be
connected to exit terminals 3 and 4 (see fig. 9).
Connector “L” – PT1000 temperature sensor and CO2 sensor (see figs 3 and 10)
OJ GreenZone™ Module M is equipped with inputs for analogue sensors (see figs 3 and
10).
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 1, 4 and 6 of the RJ12 con-
nector (see fig. 10).

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 PT1000
sensor connected to this input (“L”) will automatically be configured as an inlet sensor.
Connector “M” – Temperature oset (°C) (see figs 3 and 11)
OJ GreenZone™ Module M 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 ETFWP-998 temperature oset potentiometer is a standard product from OJ Elec-
tronics which has both PT1000 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 M 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 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 ac-
tive when the window(s) is(are) closed. The input is factory-equipped with a jumper.
