1. Des ription
The THERMO data logger monitors temperature and humidity, and transfers the
information to a secure web based database on pre-determined intervals.
Typical applications include fridges, cold rooms, air conditioned server rooms etc.
The system consists of a THERMO Unit, 1-Wire sensor(s), power supply and a web based
central database called Signal Tower. The THERMO unit can be installed in a convenient
location and the sensor(s) are positioned where critical temperature and / or humidity
measurements are to be taken.
The unit is equipped with two 1 wire sensor inputs. It can accommodate two temperature
sensors or one temperature and humidity combination sensor.
Using Signal tower, each sensor channel can be set up to record temperature or humidity
levels at configurable intervals. In addition, high and low thresholds are set up, and alarms
are sent by either or SMS and e-mail. An audible alarm is also activated on the THERMO
unit.
Other alarms include Mains Failure, Mains Restored, Battery Low, Unit Tamper, Sensor
Disconnect, Sensor Connect, etc.
The secure database is used to do all reporting, e-mailing of graphs, setting up of alarm
conditions, maintaining client and notification recipients etc.

3. Sim Card Installation
Make sure the sim card's pin code request is disabled.
The sim card must be able to send SMS messages and have Data (GPRS).
Remove the 4 grey round screw covers at the back of the unit and unscrew the 4 screws.
Remove the back cover and insert the sim card into the sim card holder on the pcb. Check
that the sim card is properly inserted.
Please make sure that the battery is connected to the provided white 3 pin connector on
the pcb before closing the unit.
Put the back cover back and close the unit using the 4 screws. Refit the grey screw covers.
Note: The unit can also use a sim chip type sim card. This must be fitted by the
manufacturer of this unit.

4. Unit Installation
Install the temperature sensors and route the wires to the Thermo unit. Label the wires
close to the connector with the input number (1 or 2) that it should be connected to and the
description of temperature being measured. E . 1 - Fridge, 2 - Freezer, 2 - Aircon 1, 1 -
Room Temp.
The sensors will take a while to reach the new environment’s temperature, so install them
first to give them time to adjust.
Put or mount the Thermo unit in the desired position and plug the power supply into a 220V
AC power source. Connect the power supply’s DC Jack to the Thermo unit. The unit will
switch on. Please see Unit Startup(Section 5) for more information.
Connect the sensor cable(s) to the unit on the unit. The top connector is for channel 1 and
the other connector is for channel 2. Temperature and humidity combination sensors can
be connected to any channel connector. These sensors use two channels on the unit and
will display the relative humidity on channel one and the temperature on channel two.

5. Unit Startup
5. Normal Startup
The unit starts with a blue screen and display THERMO startup in the first line. The unit
shows the status of the startup process and will show
THERMO Startup
Swit hing GSM ON... = GSM module is switched on
GSM ON... = GSM module is on
SIM dete ted! = Sim card has been detected
SIM registered! = Sim card has registered on the network
GSM Signal = xx% = GSM Signal strength is xx
5.2 Low Battery Startup
Battery harging If a unit starts up with this screen it means that
Please wait.... the internal battery level is too low for the unit
to work correctly. It will charge the battery up to a safe
level and will then start up. This battery charging
process can take anything from a few minutes up to 1
hour, depending on how discharged the battery is.

6.2 Mains Status:
The mains status is indicated by this indicator.
Mains on
Mains off
NOTE: When the mains fail, the backlight is switched off after 5 seconds to save battery
power. Press on the display to switch the display backlight on for 5 seconds.
6.3 Signal Strength:
This indicates the GSM signal strength.
Signal strength less than 20%
Signal strength between 20% and 40%
Signal strength between 40% and 60%
Signal strength between 60% and 70%
Signal strength between 70% and 80%
Signal strength better than 80%
6.4 Communi ations A tivity:
This indicator indicates when the unit is communicating with the server via GPRS.
Data is transmitted to the server
Acknowledgement is received from the server

THERMO
THERMO - Manual Ver 01.00 Page 11
6.5 Unit ID:
The unit's ID is displayed in the top right hand corner. Typically something like OWC00001.
6.6 Time:
This is the unit's time. It is updated once per minute. When the unit is switched on this will
be blank but it will be displayed once the unit has updated its time from the server.
6.7 Channel x Name:
This is the name of the channel. It will give you an idea of were the sensor connected to the
channel is installed. E amples are : Fridge1, Big Freezer etc.
6.8 Channel x Value:
The live value read from the sensor is displayed here. If the value is displayed in green then
the value is within the normal configured range. The value will be displayed in red if it falls
outside of the valid range.

7. Bootload Fun tion
Firmware Upgrade
Downloading...
. % Complete = Downloading progress from 0.0% to 100.0%
Done! = This is displayed after the download was
successful. Do not do anything, leave the unit
as is with everything connected and mains
switched on.
The Thermo unit has the functionality to be able to update its own firmware over the air. It
is initiated by the manufacturer when there is new firmware updates or features. All other
functions on the unit will be disabled while it is downloading the new firmware and
installing it onto the device. After the bootload is complete the unit will restart with the
new firmware. No interaction is needed by the user. It usually takes about 30 minutes in
total to complete but this can take up to 1 hour when the GSM signal strength is low or if
network problems is e perienced. If the unit is unable to download the new firmware it will
try a few times and then it will restart and continue to work on the previous firmware
already loaded on it.
8. Swit hing The Unit On
Take the power supply and plug it into the 220V AC wall socket. Take the wire on the other
side of the power supply and plug the DC jack into the Thermo unit. The unit will switch on.
Please see Unit Startup(Section 5) for more information.
9. Swit hing The Unit Off
To switch off the unit, unplug the DC jack from the Thermo unit. The unit will send a unit
off message and then it will switch off. It can take up to 5 minutes for a unit to switch off
after the DC jack was unplugged.

10. Sensors
There are two sensors that is compatible with the Thermo. A temperature sensor and a
temperature and humidity combination sensor. These sensors are described in detail
below.
10.1 Temperature Sensor
This sensor measures temperature of air or liquid and is waterproof. The measurement
range is -55°C to +125°C with resolution of 0.1°C and accuracy of ± 0.5
o
C between -10°C
and +85°C. Standard cable length is 2 meter or 5 meter and can be e tended up to 40
meters. The Thermo unit can support two of these sensors and each sensor uses one
channel.
Typical applications where this sensor can be used:
•Fridges
•Cold rooms
•Temperature controlled environments
1- Wire Temperature Sensor Image

THERMO
THERMO - Manual Ver 01.00 Page 14
10.2 Temperature And Humidity Sensor
This sensor measures temperature and humidity of air. The temperature measurement
range is -40°C to +80°C with resolution of 0.1°C and accuracy of ± 1.0
o
C. The humidity
measurement range is 0%RH – 99.9%RH with resolution of 0.1%RH and accuracy of ± 3%.
Standard cable length is 1 meter and this is the ma imum length the cable can be. The
Thermo unit can support one of these sensors and uses two channels on the unit. Channel 1
is humidity and channel 2 is temperature.
Typical applications where this sensor can be used:
•Server rooms
•Air conditioned environments

THERMO - Manual Ver 01.00 Page 15
11. Message Que Handling:
All SMS messages and important messages will be send immediately. If there is a problem
with the GPRS communications to the server, the important messages will be send with SMS
to the server.
The messages that is used for logging will be stored in a buffer and will be send with GPRS
when it is available. If GPRS fails it will store the messages and retry once a hour to resend.
There is a setting to set the que length, once this que is full there is two options. Delete the
oldest messages or SMS them. Only the messages that can not fit in the que anymore will
be deleted or SMS'ed depending on the configuration. If GPRS starts to work again then
everything in the que will be send with GPRS starting with the oldest messages first.
