INTRODUCTION
The WT-1672D GSM Remote Monitoring & Remote Control Switch is capable of monitor 2 digital inputs, 1 x
20A relay output, 1 timer input, and power outages notification function. One of the digital inputs can turn
to pulse counter input.
The unit can monitor 2 digital inputs. A call and SMS alarm message will sent when inputs triggered. The
system is able to load up to 5 numbers in the white list as authorised users. One of the digital inputs can be
pulse counter alarm input. The input alert message can be edited and programmed up to 40 characters long.
User can change the display text by sending the SMS text commands to the units.
The unit also has 1 x 20A heavy duty relay output can be used to switch on any application like lamps, pumps,
heaters, motor etc. Output relay can be switched ON or OFF by calling its cell phone number or by sending an
SMS command, there is no call charges incurred when dialling the unit as it will recognize an authorised
telephone number calling it and reject the call without answering. One Call to the SIM Card Number will switch
the device OFF permanently. Another Call to the SIM Card will switch the device ON permanently.
The GSM Remote Control system supports timer function, the user can set schedule to turn on / off the switch.
For example, put your pump, motor on a schedule. “Turn off in 5 minutes”, “turn on at 17:00, “turn on 1 year
later”
This function is important to use in the renting and leasing industry of electrical appliances, heavy vehicle, and
rental of site equipment to turn off the machines when off hire time completed
This function also important as the reminder to the owner to monitor the SIM Card expiry date. User can
instruct the unit to trigger the relay in the specified times and sent the SMS to the user to keep the SIM card
active when expiry dates.
The unit equips 1 pulse counter input, the range is 00000~59999. The user can setup start value, interval alert
value alert, interval time to alert, total value to alarm, when total value alarm occurrence, it can active the
relay outputs and sent SMS or dial to authorize phone number.
The unit detect loss of power. Once power outage is detected, the unit will call and SMS to your cell phone
and / or sound an auditable alert to make you aware of the power failure. The system using CE and FCC
approved industry internal power supply connected on board. A backup lithium battery can power up at least
8 hours and will sent a power down or power restored alerts in the event of power failure

SETTING UP AND PROGRAMMING
When first booting up the system you will see Green LED Lights on the side of the Enclosure and it should light
up when the Network is applied to the unit.
The Green LED is the network Indicator and this will light up when attempting to log on to the network flash
inconsistently until it locates the network.
A Phone Call to the SIM Card Number will now Latch the Relay permanently ON and Switch the device being
Controlled On.
The Status of the Relay will remain as on, until the unit receives a second Call to the Unit of which will now
Latch the Relay Permanently off.
Both Calls used to Latch the Relay either on or off are automatically disconnected, once the relays are
activated and never incur any Network Call Costs.
Beside calls to switch off or on, the unit also can be permanently switch off and on by sending the unit a text
message command

Step 3 - Installation
Insert the SIM card, to access the SIM card carrier gently push the button adjacent to it, insert the SIM card
and carefully close the carrier
Connect the cable to terminals 220V & N ensuring positive is connected to terminal 200V, switch on the power
supply , the red power LED will light indicating power is present, the blue network LED indicator will initially
flash quickly, once logged onto the network , it will flash more slowly approximately one every 3 -4 seconds
It is recommended that the GSM Remote Control Switch be programmed to operate as required before final
installation.

Preparing the SIM card
All new SIM cards have to be registered with the network provider before they can be used, usually by calling
the network provider or registering on their website please refer to the instructions supplied with your SIM
card.
During the registration procedure a confirmation code or text message is usually sent to the SIM cards
telephone number, to be able to read and react to the message you will need to insert the SIM card into an
unlocked mobile phone.
After successfully registering the SIM card, ensure there is sufficient credit on the card for programming
confirmation texts to be sent from the GSM Remote Control Switch.
You MUST ensure that the PIN request is disabled from the SIM card before inserting it into the GSM Remote
Control Switch. If you do not disable the PIN request the GSM Remote Control Switch will not work. If the PIN
request is not disabled and the unit is switched on more than 3 times you will have to reset the PIN using the
PUK code which will have to be obtained from the service provider.
To check the PIN request status of your SIM card, place the card in an unlocked mobile phone, switch the
phone on. If you are able to make calls without entering a PIN number the PIN request is disabled. If a PIN
number is requested refer to the instructions supplied with the SIM card and then look through the phones
options for the ‘disable PIN request’ and disable it.
You MUST disable any voicemail that is set up on the SIM card; the codes shown below are for UK networks
only, please refer to your network operator if outside the UK
Vodafone: 1210 >Send - you will hear ‘order is accepted and confirmed’
O2 - Call 1760 >Send - you will hear ‘order is accepted and confirmed’
T-Mobile - Call 222 and follow instructions
Orange - Call 450 and follow instructions
The SIM card is now ready to use
We recommend that if you are using a ‘pay as you go’ (PAYG) SIM card that you choose to automatically ‘Top-
Up’ when the cards credit falls below a certain limit please contact your network provider or visit their website
for more details.
Most but not a using post-paid SIM cards will be de-activated by the network if not used to make an outgoing
voice call or send an SMS text message within a specific period. To prevent this simply send the GSM Remote
Control Switch a text command *0*PW#, then *2*, it will reply by text message, do this once a month to keep
the SIM card active.

Troubleshooting
1. Red power LED not alight
Ensure that your DC power supply is connected
correctly, positive (+) to terminal 220v and negative (-)
to terminal N. Verify 12 volts is present using a volt
meter
2. Blue network LED flashing every one second
and not every 3 seconds
Ensure your SIM card has been activated and that the
PIN request has been disabled. If the unit is in a low
signal strength area consider using an external GSM
antenna or changing to another network provider
3. I am not receiving confirmation test messages
when program the administrators number
Ensure your telephone number is in the Administrator
list and that sending text messages to your number is
enabled.
4. I am not receiving any text messages when
initially programming the unit
Ensure the unit is connected to the GSM network by
observing the blue network LED; it should be flashing
once every 3 seconds (see 2 above). Ensure the SIM
card has credit
5. The unit has been working for several months
and has now stopped responding to calls and
text commands
Most but not all PAY SIM cards will be de-activated by
the network if not used to make an outgoing voice call
or send an SMS text message within a specific period.
To prevent this simply send a txt command *0*PW#,
then *2*, it will reply by text message, do this once a
month to keep the SIM card active
