For wall mounting:
Follow steps 1 - 3 in Figure 2.
Turn off power and put a flat head screwdriver deep inside the
hole on the bottom of the alarm housing, then depress the clip
slightly to remove the face plate from the wall plate.
Move the top of the house apart. Mount the unit on the wall.

Important Safety Information
-
Always turn off power before mounting, removing and clearing the alarm. Notice the supply
power voltage: 24Vac/dc
Mounting and Wire Connection
-
Do not mount it behind a door, in a corner or near a heat source, diffuser or
any steam
source or in direct sunlight.
-
If the monitor uses the power adaptor to supply the 24Vac/dc power, plug the output end of
the adaptor into the power socket.
Operation
Turn on power. A red spotlight at a lower position on the cover can be seen. Meanwhile
the LCD display in green is activated. Values for temperature and relative humidity are
displayed on the upper line of the LCD. The second line showes the ozone level. See fig. 3.
Analog output selection
If you want to change the analogue output, please follow the following steps:
a.
Turn the power off and remove the back cover. You can see two jumpers, S1 and S2, in the middle of the circuit board.
Connect the right two pins of the S1 and S2 - the analog output is voltage output.
Connect the leftmost two pins of S1 and S2 - the analog output is current output.
b.
There are another two jumpers, J1 and J2, in the upper left of the circuit board.
When the J1 is connected the analog output is 2-10Vdc or 4-20mA output.
When the J1 is disconnected, the analog output is 0-10Vdc or 0-20mA output.
c.
The J1 and J2 are just for testing before leaving the factory.
The default is 4-20mA. Do not change them!
