command or local controlled by its function buttons. It is
an intelligent power supply socket that can be controlled
anytime and anywhere by users’ mobile phone.
COMPUTHERM
GSM158 is designed for any electrical ap-
pliance for business or family use up to 16amp output with
a power consumption of up to 3KW.
When used with the removable temperature sensor
COMPUTHERM
GSM158 can switch power on or off
according to the environment temperature. It is suitable
for power control of heating or refrigeration equipment by
keeping the environmental temperature within a preset
range or xed temperature value.
All services and functions need to be supported by the
GSM network and a SIM card.

INFORMATION
1. Purchase a GSM SIM card (mobile phone card)
from GSM network provider and insert it in the
socket. This SIM card number is referred as
COMPUTHERM
GSM158 number on this brochure.
2. The user needs to activate the PAYG SIM with
credit and disable the pin code function then the
COMPUTHERM
GSM158 is ready to programme.
We recommend before choosing your network
provider you check their signal strength where the
socket is to be located.
3. Be sure to keep the Password and mobile number
safe and we recommend you change the preset
password of 1234. Do not disclose this information
to anyone other than the authorized users in order to
ensure no misuse.
NB: Although we recommend PAYG SIMS for easy access
and set up of the
COMPUTHERM
GSM158, contract
SIMS can also be used but as we are only sending SMS
messages as PAYG SIM is very cost effective.

• Turn the power switch to “OFF” position.
• Insert SIM card into SIM bay and push it gently inside
until you hear/feel a click, so it becomes locked inside
bay.(To remove SIM from the socket, gently push the
SIM inside the bay until you hear/feel a click again, card
will become unlocked and now pull it out of the bay.)
• Insert the temperature sensor into the temperature
port until it is seized.
2.2 GSM Power on/off
Power on:
1. Turn the power switch to “On” position (see 7 on
Figure 1)
2. Plug the GSM158 into AC power socket.
The “Green” power light will illuminate and the
“Blue” GSM light will ash for about 20 seconds
before staying on constantly to conrm GSM sig-
nal available. A long “beep” tone can be heard (if

et. SMS command & “ ” button is disabled.
Note: The unit can be turned off by the switch (See 7
Figure 1) when not required for a period of time or by
pressing the “ ” button for 1 second (See 3 Figure
1). The GSM network signal in the socket location can
affect the unit’s functionality and therefore we recom-
mend that the signal strength is tested before lugging
external devices into the socket to be controlled. This
can easily be done by sending an SMS to the socket
rst time to see the response time which will indicate
signal strength in addition to a continuous blue light.
2.3 Add a Master number to the socket

2.5 External power supply notication
Lost external power supply:
If the plug of the GSM158 is disconnected from external
AC power or lost of the AC power occurs, all functions of
the socket are deactivated including the M button and will
notify the user “Main Electricity Supply Lost” together
with temperature reading.
The unit will notify the user “Main electricity supply lost
Temp:18C”.
Resume external power supply:
If the AC power of the GSM158 is available again, the
SMS notication will be sent to the user “Main Electricity
Supply Restored, Status: ON/OFF Temp:18C”.
When the external power supply is resumed, the output
of GSM158 will keep the same status as that of before
the external power supply failure if the power switch of
the GSM158 is not turned off. For example, if the output
is switched on before the external power supply cut off,
the output will be switched on when the external power
supply is resumed. If the power supply is switched on and
off frequently, GSM158 will send reminding SMS.
