The RGT-03 is an automatic SMS programmable
control device made for the temperature control of
apartments, weekend houses or even whole
buildings.
The
selectable
algorithms make it ideal for the operation of gas,
oil, electric heating systems (including pumps) and
air-conditioners. The built in GSM unit provides the
remote access and guarantees the exact timing.
Distant programming and the inquiry of data is
easily done by simple SMS messages, while the
controller also can be set on the spot with three
buttons and an LCD display.

    RGT-03 PROGRAMMABLE GSM THERMOSTAT USER GUIDE The RGT-03 is an automatic SMS programmable control device made for the temperature control of apartments, weekend houses or even whole buildings. selectable pre-programmed algorithms make it ideal for the operation of gas, oil, electric heating systems (including pumps) and air-conditioners.

  • Page 2: Installation

    Installation Location of mounting Since the RGT-03 is the control unit of the heating/cooling system, it is very important to find the proper place for it. The heat sensor (thermistor) is inside the control unit by default, but optionally an external sensor can be mounted at a maximum distance of 30m. In that case, the connection is maintained by a 2-conductor electrical wire.

  • Page 3: Initial Setup

    SMS command later, when the control unit is turned on.) Now the card is ready to be inserted into the control unit. Before reinserting the cover, the initial setup is to be done to adapt the RGT-03 to the actual application.

    RGT-03 GSM Thermostat 4. Break circuit with jumper JP3. That makes the set parameters stored in the permanent memory and returns the controller to normal operation mode. This setup procedure can be repeated, and the set values can be changed at any time.
  • Page 6 The number of the phone must be stored in the RGT-03. The clock of the control unit is reset each time at power back up. If it is necessary, an SMS command can synchronize the clock, so no needs manual adjustments.

  • Page 7: Troubleshooting

    The RGT-03 is able to function as a simple thermostat even with no SIM card installed. If so, the ’SIM ERROR!’ message will be displayed for 10 seconds after the unit is turned on. Whilst the clock cannot be set without a SIM card, only MAN (manual) operating mode will be available.
  • Page 8 RGT-03 GSM Thermostat Measurement error due to the resistance of the connecting cable needs to be compensated in the following way: Move the jumper on the circuit board of the heat sensor (RGT-ET) to the position shown in the picture. By doing that, you replace the heat sensor with a 10Kohm reference resistor.
