SIM CARD
ACCESS INSIDE
2
The SIM card receptacle is intended for 3V SIM cards [GSM 11.12 phase 2+].
The SIM card must be inserted in the cardholder to put the unit into operation.
Make sure that there is no voltage applied to GsmComfort+.
Disconnect also the backup battery, if any. Following the figure below:
1
1. Unlock the top cover using
a small screwdriver.
2. Slide up the top lid.
2
Serial communication port and
optional backup battery are located
inside the unit.
If the unit is provided with UPS
feature, a backup battery can be
installed to keep the device
working even during power failures.
Once the front cover has been
removed:
Before to open the unit disconnect
power supply and all live circuits
that may be connected.

The front cover must be removed to
access the inside of the unit :

3. Insert the SIM card in the
receptacle, contacts must be
on the bottom side.

1. Push with two fingers on
top and bottom sides of
front cover to release it.
2. Pull the front cover and
keep it in a safe place.
To remove the SIM
card repeat operations
1 and 2, gently pull the
SIM card out.
1. Clip the battery to available
connector. This connector
must be isolated when
operating without backup
battery.

2. Push the battery into
retainer lids located under
front cover.
3. Replace the front cover to
close the unit.

ACCUMULATORS ADHERE TO
RELEVANT REGULATIONS

Do not operate without top cover, once the
SIM card has been inserted replace the top
lid and then connect power supply.
The newer NiMH batteries are less harmful to the environment, have a longer life,
and contain recyclable materials. Recycling options available in your local area
should be considered when disposing of this product. Do not dispose of in fire.
SIM PIN
Operating without SIM PIN
The simplest way is to put your SIM card into a cellular phone and
program it so it won't ask for the PIN. The SIM card is 'open' and
someone could steal the SIM card, use it and read the information inside.
Enter default SIM PIN
GsmComfort+ comes with a default PIN = 0000 (four zeroes).
Put your SIM card into a cellular phone and program the PIN using the
given number.
Change default SIM PIN
Using com port and GsmSuite running on Microsoft® Windows®
PC you can modify the default PIN on both GsmComfort+ and SIM card.
WARNING
If you insert a SIM card that asks for a PIN number different from
that stored into GsmComfort+, the device will not operate.
If you enter the PIN 3 times incorrectly, SIM card will lock up and you
must provide the PUK (PIN Unblocking Key).
STATUS SMS
To improve the readability of information sent by this device it’s suitable to provide
some specific information: a supervisor can issue the following SMS:

mailbox if a a valid address is provided.
SMS CONTROL
Store first supervisor
Although it is not mandatory to store a supervisor, you may add a supervisor who
then has additional special commands only available to him (advanced manual).
To store the first supervisor, once the unit is operative, issue the following SMS:

The telephone number of SMS sender is automatically collected from the
incoming call presentation (thus the telephone number must be kept visible) and
will be assumed as the first supervisor’s telephone number.
First supervisor will be stored at position 401 and the unit will send back a
confirmation or error SMS.
Dots are allowed ONLY within the email address field.
It’s possible to use both ? and @ characters before the domain name.
SMS delivery failure is usually less than 1% but you must keep in mind
that a message could not arrive and you cannot complain with your
operator for this. GsmComfort+ deletes any pending SMS at power-on.
Any registered user can control outputs by means of SMS.
Following default commands can be changed to any custom text using GsmSuite.

FREE CLIP CONTROL
Incoming voice (or fax) calls from registered users will toggle regulation on to off or
vice-versa. A ringback will be issued only when enabling the regulation.
If the user waits online, after 15” GsmComfort+ will answer, playing a low tone when
output was released or four high tones after output activation. No ringback will be
issued in such case. Regulation status is recovered after blackouts.
REGULATION
The comfort setpoint can be modified by supervisors issuing the following SMS:
Setpoint=xx
XX = TEMPERATURE TO REACH
Once regulation is enabled output 1 will be activated until setpoint is reached.
To operate in pure on/off mode, without setpoint, set comfort temperature to 0.
In such case the output will stay on until next off request.
GsmComfort+ can operate in heat or cool mode. Operating in heat mode an antifrost
protection is active, turning on output 1 when temperature is below safe limit (5°C).
To disable antifrost protection set antifrost temperature to 0.
Special control SMS are reserved for supervisors only:
Stop
Disable free calls control feature (CLIP): incoming calls will be rejected.
Start
Enable free calls control feature (CLIP): incoming calls from registered users will
activate outputs following the specified sequence.
