1. Setup overview
You will need:
SIM card:
SIM must operate on the GSM (2G) network for this version. Check with your SIM supplier.
Credit on the SIM (we recommend automatic top-ups)
The SIM is not PIN protected
The SIM is set to disable voicemail
Avoid SIM cards that deactivate automatically if the SIM is not used often. If your G031 is likely to
be unused for long periods of time, you will have to send the G031 an update request periodically to keep
the SIM card active. The time limit is often three months.
2. Power supply cable: long enough to reach your device in its final location.
3. Check there is mobile network reception for your SIM card in the location that your device will be
installed (you can check the SIM card in a mobile phone).
4. Temperature sensors (included) which come in 1, 2 and 6 metre lengths and can be shortened or
extended (we recommend a maximum of 8 metres).
5. Optional liquid cell 12.0V battery: Can be plugged into G031 for backup power.
Installation
1. Download and install the APP https://www.quark-elec.com/downloads/APPs/
2. Select G031 location: location must be indoors and not exposed to water or high humidity.
3. Connect the relays outputs (if required): check relay setup for whether you want relays in normal
open (NO) or normal closed (NC) position. See back page.
4. Connect alarm inputs (if required) to the correct terminal: alarm inputs (INT) 1/2 will activate relay 1/2
respectively. The G031 is compatible with inputs that send signals as a switch (by closing the circuit) and
alarm inputs that send a low voltage signal.
5. Connect temperature sensors by inserting the connector block into the slots at the back of the G031.
Good practice is to label each sensor and its corresponding relay. This will help later on.
6. Insert your SIM into the G031 device (make a note of the SIM number first for reference).
7. Connect to power: Check LEDs are working correctly.
Blue Network LED: LED will flash blue at start up as it is connecting to a network. Once
connected, the LED will flash once every 2 to 3 seconds.
Red System LED: will flash at 1 second intervals once the system has finished initialization. The LED
will not flash while the G031 is processing a command.
8. Hold down reset button for 10 seconds.
9. Register the main phone number that will control the device within 10 minutes of powering up
the G031 by texting ‘88888888’ from your chosen phone to G031 SIM card. If registration is successful,
the module will reply with ‘Your phone has been registered’. If unsuccessful, the module will reply with
‘registered disabled’. If registration is unsuccessful, Hold down reset button for 10 seconds and
reattempt registration within 10 minutes. The system LED will flash at one second intervals once the
registration is completed. You can add up to three additional control mobile phones (check the manual for
full list of text command codes).
You can send commands and receive updates by SMS text or the text generating android APP.
Remember; the device processes one command at a time. Each command will have a reply to
confirm the command has been received and executed. You must wait for a reply message before
sending another command.
(This is an overview only. Familiarize yourself with the manual before installation.)

2. Introduction
The G031 series remote controller is a versatile device which can be attached to many electronic devices
in homes, offices, plant or wherever required. It includes three independent relay switches and two digital
alarm inputs. It allows operators to control/monitor remote temperatures or equipment using SMS (Short
Message Service) via the GSM network. It also allows for automated temperature or alarm activated
action. Up to 4 mobile phone numbers (SIM card numbers) can be registered with the remote controller.
These mobile phones can belong to technicians, engineers or individuals who have a requirement to
control and/or monitor corresponding devices.
The G031 features:
Three relay output connections: for connection to the equipment that is to be controlled
oRelay 1: Manual SMS control, Automated control, Daily timer
oRelay 2: Manual SMS control, Automated control, Daily timer
oRelay 3: Manual SMS control
Three thermistor temperature sensors: with three linked relay outputs.
Two digital alarm inputs connections: for connection to various inputs to be monitored (an alarm
SMS can be received when either alarm input is triggered. The alarm input can also be set to trigger
automated control of the machinery connected to the Relay outputs 1 and/or 2).
Four control mobile phones: one main control terminal and up to 3 additional control terminals can
be registered with G031.
Android APP: the device can be controlled by either SMS text message codes or the text
generating APP for Android phones. This is a touch sensitive, user friendly interface.
Optional battery input: to allow the device to keep running during a power break. it has the Added
benefit of battery charging once the power is restored.

4. Power connections
4.1.12.0V DC power connection
The G031 module can be supplied by 12.0-24.0V DC power. Connect a 12.0V DC power supply to the
power input screw terminals and switch on the power supply. The red system LED will flash at 1 second
intervals once the system has finished initialization. The blue network LED indicator will initially flash
quickly and, once logged onto the network, it will flash more slowly, approximately once every 3 seconds
4.2.Battery connections
The G031 supports backup battery inputs. The battery can be an auxiliary power supply for operation
during mains power failure. A 12.0V rechargeable Li-ion or Lead-acid battery can be connected to battery
input terminals on the G031.
Connection to a battery can allow the G031 to operate for up to a few days (depending on the battery
capacity) without mains power. The G031 will alert the operator when mains power has been lost and
recovered. The battery will recharge when power is restored. When recharging the battery, the mains
power input should be at least 2.0V higher than the battery’s full voltage level. Therefore, the mains
power supply voltage should be 14.0-24.0V.

5. Status LED’S
The device has two working LED’s to notify the user of its operations.
Blue Network LED – Blue LED will flash at start up as it looks for a network signal. Once a signal has
been found the LED will flash much slower, every 3 seconds.
Red System led – Red led will flash at 1 second intervals once the system has finished initialization.
It will not flash while it is processing a command.
Remember, the device processes one command at a time. Each command will have a reply to
confirm the command has been received and executed. You must wait for a reply message before
sending another command. All SMS text commands must always be sent using CAPITAL
letters. Do not add spaces or any other characters.

6. Preparing SIM card
Please ensure:
The SIM must operate on the GSM (2G) network. Most network providers provide 2G cover, check
with your supplier.
There is credit on the SIM (we recommend automatic top-ups)
The SIM is not PIN protected
The SIM is set to disable voicemail
Avoid SIM cards that deactivate automatically if the SIM is not used often (usually after3 months
inactivity). If you’re SIM will do this and if you’re G031 is likely to be unused for long periods of time;
send the G031 an update request periodically to keep the SIM card active.
Register the SIM card; ensure there is sufficient credit on the SIM card for programming confirmation
texts to be sent from G031 module.
The PIN request option should be disabled from the SIM card before inserting it into the G031 module. To
check the PIN request status of your SIM card, place the card in an unlocked mobile phone and switch
the phone on. If normal calls can be made without entering a PIN number, then it is disabled. Please also
make sure voicemail is disabled before inserting the SIM card into the module.
If a ‘pay as you go’ (PAYG) SIM card is used, it is recommended that users choose to automatically ‘Top-
Up’ when the credit falls below a certain limit. Some PAYG SIM cards will be de-activated by the network
if they are not used to make an outgoing voice call or send an SMS text message within a specific period.
To prevent this, simply send the G031 a text for example ‘DQSJ’ (this can be done through the APP) and
G031 will reply with the local time by text message. This should be done periodically to keep the SIM
card active if required by your SIM provider.
6.1.Insert SIM into the SIM card slot
1. Write down SIM number before inserting into the G031
2. The SIM card should be inserted into the SIM card slot before applying the power.
3. Power Up (See next chapter)
6.2.Registration of Main SIM Controller
Users can setup the authorized telephone numbers within G031. The controller will verify the incoming
number if they are indexed in the registered SIM numbers, then the G031 controller will hang up and then
execute the actions.
The following steps are required to configure G031 for first time use:
Insert the SIM card into controller box
Power up and hold reset button for 10 seconds
Within ten minutes of resetting Text ‘88888888’ by SMS to the G031 controller. If successful, the user
will receive the message ‘Your phone has been registered’. This command should be received
within the first 10 minutes after powering up G031, otherwise the message ‘registered Disabled’ will
be received. If this happens reset.

6.3.Registering additional SIM controllers
You can add up to three additional control mobile phones. When adding additional numbers to the unit
you must enter them in the correct format used by the Network service provider of the SIM that you have
entered into the G022. For example, if the UK number 07123456789 needs adding; then we have three
formats to try (Using the UK country code '44').
1. [phone]
2. 00447123456789
3. 07123456789
The most commonly used, is format 1, this will work with most providers. To store your number, text
‘BD1+447123456789F’ to the device. If you are able to send commands from the new number but do
not receive messages back, try one of the other formats.
You can now control the device by either:
Manually entering the codes by SMS text message
Using the phones Android APP interface. Using the APP, simply select the action you want and the
APP formulates and sends the SMS message for you.
App sent messages will be charged at your normal text rate.
7. Resetting
The G031 has two types of reset. You can:
Factory reset the module itself.
Reset the main SIM controller SIM number (main mobile number in control of module), whilst
keeping other settings.
7.1. Factory reset G031 memory
1. Hold the reset button for 10 seconds – the red LED should stay constantly on.
2. You now have 600 seconds to send the message ‘88888888’ to the SIM card in the G031
3. This will register you as the main SIM controller.
You can also reset the Main controller SIM remotely, For example when the main SIM controller number
has changed or you need to reset permissions for the main controller. This code allows you to remotely
remove and reset all mobile phone numbers stored in the device.
7.2. Reset main controller SIM number
1. Send ‘XGZHM’ command via text to the G031 SIM.
2. send ‘88888888’ within 600 seconds to the G031
3. The module will reply with ‘Your phone has been registered’.
If the G031 replies with the message ‘registered disabled’ or ‘Registered not allowed. Please Factory
reset G031 module first’ then repeat factory reset steps.

8. Alarm function connections
G031 has two external alarm input connectors and various inputs can be connected to them. For
example, door/windows sensors, smoke alarms, carbon dioxide detectors, motion sensors, thermostats,
temperature/wind detectors, and moisture detectors.
Using these sensors/detectors, G031 can be setup as a protection/alarm and response system.
Alarm input port
Corresponding relay number
External alarm 1 (INT1)
Relay 1
External alarm 2 (INT2)
Relay 2
There are two typical ways the external alarm inputs can communicate with G031. External alarm devices
can be used as,
1. Switch
2. Alarm input source (low level voltage signal)
G031 external alarm inputs are active when a trigger pulse or a constant level of 0.0V is applied.
If the sensor/detectors are triggered (low level signal (0.0V) to G031); G031 will send out an SMS to the
registered mobile terminals. Meanwhile, the corresponding relays setup will be activated.
To disable the external alarm input, text 'EXTGBn' (replace ‘n’ with the relay number).
To enable all external alarm inputs, text 'EXTRT'.

Quark-elec Manual

9. Relays
The G031 has three digital output relays for connection to the equipment to be controlled. The relays can
be setup in normal open and normal closed positions. Depending on the relay setup you choose will
determine how the G031 operates. For example a cooling setup must be setup using Normal closed. For
a heating setup it must be setup in normal open.
9.1. Relay wiring
Normal open position – if common and normal open are wired then relay 1 will be off when powered
up. To activate relay 1 either a message or a command must be received from the user or from input
1. This activates the relay and closes the circuit turning on the output of relay1. Use this method for
heating setup
Normal closed position – if common and normal closed are wired then relay 1 will be active while
the G031 is powered up. This can be useful for fail safe systems where the power going off in the
G031 will close relay 1 and activate the output of relay 1. Use this method for cooling setup.
It is important to understand that relays wired in ‘normal closed’ position will operate in the
opposite way than expected. In this setup ‘Relay OFF’ in the app/SMS will power the equipment
ON. This needs to be taken into account when setting up and designing the system.
9.2. Daily timer setting
Daily timer settings are for Relays 1 and 2. They support a daily timer function to control the actions of
the output. This is useful for turning the relays on and off without having to message the device.
The relays will switch to ON/OFF states according to the timer settings. These two relays also support
two working modes, self-lock and latching control.

Quark-elec Manual
https://www.quark-elec.com 12 of 28 2018
V3
9.3. Relay working mode (relay 1 and 2)
The G031 allows for two different working modes:
self-lock control
latching control
Self-lock allows for the usual function of the relay where a command from the operator or the device to
change is needed. The G031 is set to latching mode by default.
With latching controls, the device will return to its normal status after a period of seconds determined by
the user. This is useful for output devices that don’t need or want to be on for a long time after they have
been turned on. For example alarm horns which might only need to be on for 12 seconds to alert the user.
To change between self-lock and latching control, the jumpers must be moved from one connection to
another. Carefully lift the jumper unit up vertically from the unit. Be very careful not to damage
components or the jumper pins. Ideally use tweezers to lift and lower jumpers into the correct place.
There are three pins on each set of jumpers, by moving the jumper over the pins on the set will give
either relay 1 or 2 different working methods. See the table below to help with changing jumpers
Self-lock control – normal operation of relay on or off by
command from user or device timer
Latching control - which means relay go back to normal status
after a period of action (3, 6, 9 or 12) Seconds.
When an alarm is triggered, the relay will stay locked ON until
the command “EXTRT” to reset alarm is sent (even if set to
latching mode).

Quark-elec Manual
https://www.quark-elec.com 13 of 28 2018
V3
9.4. Latching mode settings
Working in latching mode, operators can configure G031 with different action times for Relay 1 and Relay
2 by setting the delay time jumpers.
The G031 provides a one off action timer command. SMS commands in ‘ONOFFRnxxx#’ format support
action times (from 001 second to 999 seconds).
‘n’ indicates the relay number (1, 2, 3)
‘xxx’ means the delay times (from 001 to 999 seconds)
‘#’ needed to end the command
More details about this command can be found in chapter Command and Response list.

action timer set as:9 seconds
action timer set as:6 seconds
action timer set as: 3 seconds

10. Temperature monitoring & control
The G031 has three attached temperature sensors each with a corresponding relay. They can be used to
control three individual zones via GSM /APP. These industrial standard sensors provide typical
accuracies of ± 0.5°C over the −55°C to +125°C (-67°F to +257°F) temperature range. Its stainless steel
probe head makes it suitable for any wet or harsh environment.

10.1. Setting Temperature Ranges
The G031 is designed primarily for a heating setup but can also be used for cooling. The wiring is
different depending on whether you are using the relay for a heating or cooling function.
The ON temperature must be at least 1°C lower than the OFF temperature.)
HEATING: For heating connect your equipment to the G031 in the normal open configuration as seen in
the table below.
Relay ON: the lowest heating activation temperature. (When colder than ‘+/-xxx‘, turn on.)
Relay OFF: the highest heater operating temperature. (If warmer than ‘+/-xxx‘, turn off.)
COOLING: For cooling, reverse the way the relays are wired. Connect your cooling equipment in the
Normal closed configuration as seen in the table below.
It is important to understand that relays wired in ‘normal closed’ position will operate in the
opposite way than expected. In this setup off will turn the relay on. This needs to be taken into
account during setup.
APP and SMS Settings provided in the next chapter.

10.2.Relay wiring and temperature settings example
There are two ways to set temperature ranges using either the APP or GSM text commands. This
chapter provides examples for both methods.
APP Temperature Settings:
To use the APP to set temperature ranges; navigate to ‘OTHER’ in the bottom right hand corner of the
APP. There will be a sub heading marked for each relay and its corresponding temperature
sensor. Each relay and temperature sensor can have individual temperature ranges. See
example in next chapter.
Heating: For heating connect your equipment to the G031 in the Normal Open configuration as seen in
the table below.
In the Android APP, in the ‘OTHER’ section: set your temperature ranges to the relevant relays.
Relay ON: the lowest heating activation temperature. (When colder than ‘xx‘, turn on.)
Relay OFF: the highest heater operating temperature. (If warmer than ‘xx‘, turn off.)
(The ON temperature must be at least 1°C lower than the OFF temperature.)
Cooling: For cooling, reverse the way the relays are wired.
Connect your cooling equipment in the Normal Closed configuration as seen in the table below.
It is important to understand that relays wired in ‘normal closed’ position will operate in the
opposite way than expected. In this setup off will turn the relay on. This needs to be taken into
account during setup.
In the Android APP, in the ‘OTHER’ section: set your temperature ranges to the relevant relays.
Relay OFF: the highest cooling activation temperature. (When warmer than ‘xx‘, turn on.)
Relay ON: the lowest cooling operating temperature. (If colder than ‘xx‘, turn off.)
(The ON temperature must be at least 1°C lower than the OFF temperature.)

Relay configuration
This is an example of a possible setup only. Your configuration will be different to the one shown.
SMS Temperature settings:
To use the text commands to set temperature ranges, you need to send a SMS command to the G031.
As above, the temperature settings correspond to a particular relay.
Set the temperature ranges by texting TEMPnxxxxtoxxxx#
n=corresponding relay number
xxxx=temperature using the format + or - XXX (X=single digit).
It should look something like ; +035. TEMP2-005to+035#
For more information about text commands see chapter command and response SMS list.

11. App on Android
The G031 APP provides a touch sensitive, user friendly interface that will write the text messages for you and
send them from your mobile device to control the G031. The app allows for up to two G031 devices to be
controlled from a single mobile operator. You will still be charged at your normal text rate for the messages
created by this app.
To download the app:
Android: The latest Android G031 APP can be downloaded from the link below. The Android platform should
be at least Version 2.1 or higher:
https://www.quark-elec.com/downloads/apps/
This is the main screen of the app. From here you can control all
of the functions of the G031.

Quark-elec Manual
https://www.quark-elec.com 17 of 28 2018
V3
11.1.Setup Main Controller SIM Number
The first page you will see when opening the app is the login page. Here you can set two different SIM
numbers (for 2 different G031 devices). Enter the telephone number of the SIM card that you inserted into the
G031 where it says ‘Device 1’ in the app. If you have 2 QK-G031 devices then you can enter the second SIM
card number where it says ‘Device 2’. The app will save these numbers so you don’t have to keep entering
them.
Input the number of the SIM card which is inserted into the
G031into ‘Device 1’. All command SMS messages will be sent to
this number via the APP.
Check the tick box to the right of the number you would like to
control. Then press the ‘login’ button.
Once the SIM card number have been stored, the APP will reply
with a confirmation message

Quark-elec Manual
https://www.quark-elec.com 18 of 28 2018
V3
11.2.Register SIM cards
G031 allows one mobile phone to function as the main controller and up to 3 additional phones to function as
control terminals. The following interface allows the operator to register, delete and check the SIM card
numbers:
Register myself as main SIM card: When starting the G031 for
the first time you will need to add the main controller SIM number
to the device. Do this by entering the mobile number you would
like to be the main controller or ‘click register myself as main
SIM card’. There must always be a main controller for each
device.
You will have ten minutes to register the main controller SIM
once you power up the G031. If not repower the device and
retry.
Register 1st, 2nd, 3rd additional SIM card: click this button to
register additional SIM cards. These additional SIM numbers are
authorized to control the G031
Check registered SIM numbers: this will give the user a list of
the telephone numbers that are authorized t control the G031
Replace the main SIM numbers: this allows for the main
controller SIM to be reset. Once this message is received by the
G031, the user will have 10 minutes to register the main SIM.
11.3.Setting the clock on the QK controller
G031 can automatically execute actions at the time set by the operator. To do this, the real time clock on the
G031 controller must be set. This page allows the operator to check and set the time on G031 internal clock.
Set clock on QK controller: To set the time on the G031 enter
the current time in the white box. The time format is 24hour (i.e.
11.55.00). When complete click submit to set this as the G031’s
time.
Check the clock on QK controller: To request the time on the
G031, click request at the top of the page. This will send a
message saying the time relative to the G031’
s internal clock.

https://www.quark-elec.com 19 of 28 2018
V3
11.4.Check relay working mode
G031 has three individual relays which support two working modes, self-lock and latching control. When
working in latching mode, the relay will action a command from a user determined amount of time (depending
on the time setting on the jumpers on the board. See chapter 11.4) and then reverts back to the previous
state. When working in self locking mode, the relay will stay active until the next command is received. The
G031 can also report the relay working status And check the temperature for each sensor via the app.
Relay working mode: This will inform the user which relays are
in self-lock or latching mode. This is for relays 1 and 2
Relay working status: This tells the users which relays are on/off
(if wired in the normal open position)
Temperature: This tells the user the temperature ranges for each
relay and whether the temperature sensor is enabled or disabled

11.6.Control panel
The control panel provides the main operating interface for turning relays on and off and setting timers. By
clicking ‘ON’ in the app, a message will be sent to the G031 turning the specific relay on. This is the same for
the ‘OFF’ button.
Relay 1, 2 and 3 on/off: clicking ‘on’ button will send a message
to the G031 controller to turn the relay into the normal open
position. You must wait for the command to be received before
issuing another command to the controller. The ‘off’ button
operates the relay to the normal closed position.
Relay 1 and 2 Timer: only relays one and two have timer
functionality. See next step for timer instructions.
Relay timer settings: set the time at which you would like the
relay to turn on and off. This is a 24 hour format (i.e. 13.55.00)
Relay timer set checking: Check the current setting of the timer
Relay timer reset: Switches off the Timer setting. This does not
affect the internal clock.
