       The MobilTherm-2ad is a GSM temperature and remote signaling module, designed for GSM based remote control, remote signal. It comes with two external digital thermometer, 2 inputs that can be activated by 8-30V dc voltage and 2 single circuit low current relay outputs with NO and NC contactors. Output relay no. #1 is switched on/off via SMS messages in bistable mode (changes only by another SMS), the second output can be configured via SMS for a given time to be switched on, so that it will automatically switch off after the configured time expires. Two small digital thermometer that can be connected to the module and it works in the temperature range of -50C and +50C. The module will automatically send an SMS to the user’s configured phone numbers when the temperature exceeds the configured minimum or maximum threshold. The user is informed about the temperature alert either via an SMS alert with user defined preset text or an automated call by the module.

       Auxiliary relay no. #1 is off by its default state and it can be switched on and off with a configuration command. Relay no. #2 is also off in its initial state, and can be switched on for a previously configured, user defined time by an SMS command. The module can be configured to handle maximum of 8 telephone numbers. It can be used as stand-alone units for both industrial and domestic use, therefore it is suitable for cooling storages, air-conditioned rooms, warehouses and temperature regulated agricultural or livestock breeding rooms. The power supply voltage range of the module is 10-30Vdc. It can be configured with our free software (which can be downloaded from our website) via an USB port or by the SMS messages sent to the module. The auxiliary inputs and outputs can be labeled by max. 16 characters. The controller SMS commands to control the relays can also be configured by the user.

       The MobilTherm-2ad GSM temperature alarm module works with a stand-alone SIM card, either pre-paid or subscription type from any provider. The integrated Li-polimer backup battery can be provided for the unit optionally, so that it can send reports about power loss and restoration of the 230Vac network. A TEST button can be found at the top of the module. The simplest module can be purchased as a complete system with industrial GSM module with the most recent software; with aerial as MobilTherm-2 panel version; with black metal enclosure as MobilTherm-2d; with black metal enclosure with innner backup battery as MobilTherm-2ad or as MobilTherm-2c in plastic enclosure that can be clipped to a “C” rail, or called “DIN” rail also with backup battery.

       The colorful LEDs located beneath the front cover indicate the status of the device. The lower, bi-color LED labeled as “Hbit” can express statuses and messages explained below. The middle blue colored LED is the "Status" led, and the upper one is yellow and labeled as “SMS” indicates the SMS and voice. There are also LEDs of inputs and relay outputs to showing their actual states. The supply connection require 10-30V. The output relays are single circuit low current relays. Their maximum rating is 1 A at 48Vdc. The high current relays’ COM (common), NO and NC (normally open or closed state) connectors also have been wired out. The module has SMA aerial connection, which can be found on the upper side of the module. Magnetic and small straight aerial can also be connected.

       The digital inputs are voltage-less type inputs, and highly protected against overvoltage. The different auxiliary devices can be connected to inputs of MobilTherm-2ad thermostat are recommended to be solid, relays, switches, reed-relays, contactors or any metal contacts. In addition, they must have low resistance and prell protection. The power supply input is protected against reverse polarity and a resettable fuse also has been installed into the device.

      It can be configured via mini-USB port, and the configuration settings can be downloaded, loaded or even read for verification purposes. The small and narrow digital thermometer sensor modules can be connected to the panel by 4 core coaxial screenedwires. The digital thermometers are operational between -50C to +50C degree and they have +/- 0.5 precision within this scale. Their default cable length is 60cm, but they can be ordered with cable up to 6m.

       The MobilTherm-2c GSM thermostat module can be configured from computer via USB-port by using our free software. First step after connecting the powered up device to the USB port is to install the modul driver to be recognized by Windows XP, Windows-7 or Windows-8 operating system. In the case that the driver is already installed but the operating system still cannot recognize the device, the operating Win system settings should be modified in that particular order as described in the appendix. The software can configure all members of the MobilTherm-2 family. After connecting the device, launching its software the downloader software will automatically search and recognize the connected device. After successful recognition, the corresponding picture of the device will be displayed in the main window of the software. The status of the device can be queried if the device is connected to a network.

      The MobilTherm-2c GSM thermostat confirms every command by sending back an acknowledge SMS. The acknowledge SMS reflects the changed parameter and the actual status of the outputs and inputs. When switching on the device, the inputs are checked and the device takes it as an initial state. Changes from this initial state will cause alarm, and the new input status will be sent via SMS. Specify the number of the SMS Center first during configuration, or else the device will not respond to the configuration commands and will not operate properly.

      The SIM PIN must be disabled on the SIM card, then it is advised to put the SIM card in a regular mobile phone to check if the SIM card is allowed to send SMS-s. Newly bought SIM cards has to be checked whether it can send SMS-s. Considering pre-paid SIM cards, showing the caller ID feature must be enabled through customer service. Setting or checking the state of this feature cannot be performed with a regular mobile phone. After programming the device, the SIM card should be inserted into the SIM holder as shown in the figure. The SIM holder is located on the front of the device. The device can be operated with any microSIM card, and the received unknown SMS-s, including the ones sent from the carrier (including the balance check SMS) are forwarded to the first telephone number, if the first telephone number is specified in the configuration.
