We reserve the right to make changes and improvements in our
products which may effect the accuracy of the information contained
in this leaflet.
Important information
1. Always cut off power before mounting, removing and
cleaning the monitor.
2. Read all of the information in this datasheet before
mounting the detector.
3. Notice the supply power voltage of the transmitter:
24Vac/dc.
Do not install the transmitter on voltages higher than
marked on the transmitter
Mounting and Wire Connection
1. Cut off power first. Simualtaneously depress the 2
clips on either of the sides of the detector gently with
your nails or other unsharp tools, then move off the
face part.
2. Mount the detector on the place where you want to
detect O3 level 0,3m above floor.
Do not behind a door, in a corner, in direct sunlight and
near any heat or steam sources.
Do not mount the detector in the direction of the outlet
of the Ozone generator or in places where wind pass
through.
3. Mount the wall plate first.
Place the detector against the wall at desired
location;
make sure wires can be passed through the
holes of the wall plate.
4. Connect wires to terminal strips, (see the label
attached on the wall plate and fig.3).
Make sure wiring connection correct and scure.
5. Cover the face part to the wall plate

Operation
1.If you use the monitor for the first time or it hasn’t been used for a long time, then it should be energized for more
than 48 hours before it come into normal use.
If you have placed it in the direction of the outlet of the Ozone monitor or in places where wind pass through, then the
measurement of the Ozone monitor will be incorrect.
In this situation, please place the Ozone monitor in normal environment and keep it energized for at least 24 hours,
and then calibrate its zero point following step 10.
Then the monitor will return to normal use again.
When the ozone measurement range overstep the maximum measurement, the ozone sensor can be resumed after
a long time rest, and then it will return to normal use again.
2.Temperature measurement range is 0~50!, accuracy 0.5!, temperature setting range is 5~45!.
Humidity measurement range is 5~99%RH, accuracy 1%RH, humidity setting range is 5~95%RH.
Ozone measurement range is 10~1000ppb, accuracy 1ppb and setting range is 40~1000ppb, its maximum
measurement limited is 2000ppb.
3.Turn on: Turn on the monitor by press power for 2 seconds.
Temperature measurement displays on the right of upper line of LCD, the humidity measurement displays on the
left of upper line of LCD.
The preheating time of ozone sensor displays on the below line and the time is set to 300 seconds(default).
The preheating time can be changed in parameter setup.
After it is counted down to 0, ozone level will be displayed.
4.Switch setting value: press switch key to exchange setting value from between ozone and temperature/humidity.
But for the model, temperature setting is un-effective.
5.Setting O3 value: Once switching to ozone setting, the ozone number is blinking, it indicates that the O3 value can be
set by (tangent down) and (tangent up)key .
Increase or decrease 1ppb each time by pressing and rapid increase or decrease by pressing key for more than 2
seconds.
6.Lock setting value: Simultaneously depress the (tangent down and tangent up)key more than 5 seconds up to the
symbol (lock) appearing on the LCD.
Then the setting value is locked to avoid wrong operation.
7.Unlock: Under the locked mode, simultaneously depress (tangent down) and (tangent up) up to (lock) disappear.

8.When DIP4 is set to OFF(details see below Parameter Setup):
The relay will turn on when O3 measurement < O3 setting with ON symbol appearing on the right of LCD.
When O3 measurement <O3 setting , the relay will turn off with ON disappearing.
When DIP4 is set to ON(details see below Parameter Setup):
The relay will turn on when O3 measurement > O3 setting with ON symbol appearing on the right of LCD. When O3
measurement < O3 setting , the relay will turn off with ON disappearing.
The differential of ozone setting, please refer to Parameter Setup.
9.The scale bards on the right of LCD indicates the analog output. It is un-effective to this model.
10.Calibration of the zero of ozone sensor: after using the ozone sensor for more than one year, the sensor need to be
calibrated again.
Put the monitor into the space of zero ozone and preheating it, press switch key for about 20 seconds until X10
symbol appearing on the right of ozone number, then loosen switch key, the monitor starts auto zero calibration.
After 210 seconds until X10 symbol disappearing, it indicates the zero calibration finished.
Cancel the zero calibration: press switch key for about 20 seconds until X10 symbol appearing and then keep on
press switch key for about 20 seconds until X10 symbol disappearing.
It indicates the zero has no any calibration, it’s still 0.
Note: Auto zero calibration can be done only when ozone measurement is above 5ppb.
And keep the controller in the zero ozone environment before X10 symbol disappears.
Parameter Setup ( Service Manual V.O3_210)
Cut off power and simultaneously depress the 2 clips on either of the sides of the monitor gently with your nails or other
unship tools.
Move the face cover, there is a set of 4 Dipswitches on the right of the circuit board.
DIP1 ON - set parameter OFF- normal use Leaving factory: OFF
DIP2 ON - Fahrenheit OFF- Celsius Leaving factory: OFF
DIP3 Un-effective for the model Leaving factory: OFF
DIP4 ON- For decrease ozone (to control ventilation system)
OFF- For increase ozone (to control an ozone generator) Leaving factory: OFF

Guidelines on How to Measure Ozone
The following information is presented to help users operate their
Ozone Detector in the most effective and efficient manner.
General
• Ozone is heavier than air and tends to sink.
Thus detection of leaks from ozone generating equipment should be performed at
the most appropriate position.
• Ozone will react and decompose on surfaces such as walls,
furniture etc.
• Smell is not a reliable test for the presence or concentration of
ozone as the odour threshold varies widely between people and
is affected by local ambient conditions.
Permanent Controller Placement
• The Ozone Detector has been designed to measure
the ambient concentration of ozone.
The controller must not be placed directly in an ozone stream.
• For indoor local area monitoring attach the controller to an inert
surface with the inlet unobstructed.
• For leak detection mount the unit near the ozone equipment.
• Ensure that the controller is protected from excessive water
splashing, dust, vibration, excessive heat or cold, high
concentrations of ozone and excessive swings in humidity.
False Readings
• The Ozone Detector has been designed to respond
selectively to ozone, however other oxidizing gases such as
chlorine and nitrogen dioxide can generate false readings if they
are at high concentrations.
High concentrations of hydrocarbon gases such as vapours of alcohol,
oils and solvents can reduce and mask the concentration of ozone.
