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 pre-programmed
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.

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. Mount the heat sensor (or the control unit if the internal sensor is used) on that wall, which has the most intense air circulation in its proximity and the nearby temperature is closest to the average temperature. Mount the heat sensor (or the complete unit) horizontally at a distance of 1,5m to the ground. Never unit) close to any source of heat (eg.: heater), in blowy areas or places where it can be exposed to direct sunlight.
Mounting
The opening for the cables and the mounting holes are located on the bottom of RGT-03. It is advisable to mount the unit above a wall­mount box by two screws. To do so, first the cover must be removed by gently unlocking the two small white tabs on the bottom edge of the cover – as shown in the picture. A small screwdriver will come handy. Once the unit is open, mark the location of the mounting holes on the wall, drill the wall, fix the unit by two screws.
mount the heat sensor (or the complete
The next step is the connection of wires to the proper terminal blocks according to the plan. Connect the leads of the included 12V power supply to terminal P1. WARNING: MIND POLARITY! Terminal P3 is for the optional external heat sensor (RGT-ET) that can improve the detection of heat. The maximum distance between the sensor and the control unit is 30m. In case an external heat sensor is used, the jumper JP1 (located next to the display) must be in position 3 (towards the display). The heating/cooling system connects to terminal P2 as shown on the plan.

The wiring should be done in accordance with local regulations. The use of a maximum 10A fuse is highly recommended.
Please note:
The person who carries out the installation must have basic knowledge on electricity. Make sure the power is cut off before any operation!
Initial setup
First, prepare the SIM card by a GSM phone and insert into the SIM holder. (See previous picture!)
SIM preparation: Insert the SIM card into a common GSM phone. In the menu, find and disable the security function that makes the phone asking for PIN number on star up. Next, type the phone number that belongs to the SIM card in the ’Own Number’ menu – or similar. (That is only to allow the control unit to acquire the time from the GSM network during turning on. However, it is not essential to do, since it can be doing with 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. Jumper JP3 and button S1, S2 and S3 will be used.
1. Turn power on and wait for displaying the time/date.
2. Make JP3 shorted by the supplied connector.
3. Scroll the menu up or down with button S1 and S2 to check each parameter. Select the one you need to change by pressing button S3. A flashing value will then indicate that the value is ready to be changed. Now use button S1 and S2 to alter the value. Press S3 repeatedly to save the value and return to the menu. The chart below shows the menu points, the default values, and the range of possible adjustment.

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.
5. Snap the cover back on to its place. The controller is ready for operation.
Detailed explanation of some expressions of the table
Temperature shift: If the control unit is installed in a too cold or warm place, the measured
and displayed temperature value can be corrected by a few degrees.
Lower temperature limit: Protects against unauthorised adjustments. The temperature can't
be set to a lower value than the limit.
Upper temperature limit: Protects against unauthorised adjustments. The temperature can't
be set to a higher value than the limit.
Pump protection: When the function is enabled, the pump will run for one minute at 2 PM
if it has not been turned on for 24 hours.
Maintenance
During operation, the display takes turns at showing the time-date and the current-set temperature value in 10 second intervals, as it can be seen on the pictures below. If there is no sufficient light to read the display the illumination can be turned on/off by pressing the OK button.
Please note:
Do not leave the illumination turned on permanently because the produced heat can lead to false temperature measurement.
In operation, two parameters can be altered on the spot: the target (desired) temperature and the operating mode. The programming method is similar to the one described under Initial setup step 3. Use arrows to change between the target temperature (displayed as: mTref or TRef) and the operating mode (displayed as: Mode). To alter a parameter, press OK then use the arrows to change value. When ready, press OK to store the new value. If no button is pressed for 4 seconds, the unit stores the set value automatically and returns to normal operation.
Operating modes:
1. MAN (manual mode): The control unit will continue to maintain the temperature set as TRef
(or mTref) until an other temperature or mode is selected. (displayed as: MTR: xx°C).
2. AUTO (automatic mode): Automatic mode sets the thermostat to follow the temperature
program from parameter P01 to P64 (displayed as: ATR: xx°C). If you change the mTref value with the buttons of the control unit while in auto mode, then the mTref temperature will be maintained until the next switching time is reached. In that case mTR: xx°C will be displayed.
3. HOLIDAY: The control unit will apply the Sunday program for the current day and the day
after (displayed as: HRT: xx°C). Like in AUTO mode, the mTRef value can be changed here also.
5 ML_RGT03_V5_english.doc
RGT-03 GSM Thermostat
Target temperature setting:
1. mTRef: In AUTO and HOLIDAY modes the temperature value can be set between the
lower and upper temperature limits. Valid until the next switching time.
2. TRef: In MAN mode, the temperature value can be set between the lower and upper
temperature limits. (The GSM remote control affects this parameter too.)
GSM remote control
The control unit has a built in GSM module that makes remote programming possible. Via an SMS you can change the target temperature or you can inquire the measured temperature, the target temperature, the operating mode and the state of the relay. The inquiry also can be done by making a phone call and terminating it after two ring tones. 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. An ALARM phone number can be set. The control unit will send a warning message to this number if the measured temperature is under the lower or above the upper temperature limit by 2°C.
In case a prepaid SIM card is used with the control unit, you can check the balance and the time of expire – if any. Always check carefully the terms of use of your SIM card at your mobile supplier to ensure continuous connection!
SMS commands (non case-sensitive)
There is a PIN number protection against unauthorised access. The PIN number can be changed at any time. The factory set value is: 1234
change PIN number:
[PIN]P[new PIN] eg.: 1234p5678
change TRef:
[PIN]T[TRef in °C, between 5 and 40] eg.: 1234t8
store phone number (up to 100 numbers can be stored):
[PIN]G[phone number in international format] eg.: 1234g+36201234567
delete phone number:
[PIN]D[phone number in international format] eg.: 1234d+36201234567
SMS inquiry
[PIN]? eg.: 1234?
Optional phone inquiry: Call the RGT-03 from a stored phone number; terminate the call after two ring tones. You will receive the answer in SMS.

Any different, irregular SMS will be automatically forwarded to the ALARM phone number.
Troubleshooting
In case, the display shows an unusual message, first press any of the up or down arrows. If that does not help, cut the power supply for a few seconds (restart).
In case, the GSM remote control function does not work cut the power supply for a few seconds. If that does not help, check your SIM balance and time of expire.
The device can be restarted by phone in the following way, if the telephone connection is working: Dial any of the numbers (inquiry or alarm) that has been previously stored in the RGT-03, wait for at least five ring tones, and then break the line. Optionally, the unit can be restarted by SMS: Send a message with the content [PIN]RR to the unit. If you want the unit to use the factory (default) settings after restart, the content of the SMS should be [PIN]RF. There will be no reply to these messages. The proper operation can be verified by an SMS inquiry. (Leave at least one minute for the unit to restart before check.)
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. During operation the ’SIM!!! MODE MAN’ message will be displayed instead of the time and MAN mode will be set automatically.
In case, a SIM card is inserted without having the security function – that makes the phone asking for PIN number on star up – turned off, the ’PIN ERROR!’ message will be displayed and the control unit will operate as without a SIM card.
In case, the own phone number that comes with the SIM card is not written on the card (as described under Initial setup) the RGT-03 will not be able to get the time data from the GSM network. False or no time at all will be shown on the display. Use [PIN]S[phone Nr] and [PIN]C SMS commands to write own number to the SIM, and set the clock.
External heat sensor option
In the case of finding it more convenient to mount the RGT-03 to a place that is fare from the optimal location for temperature measurement, it is possible to use an external heat sensor (RGT-ET). The maximum permissible distance between the control unit and the external heat sensor is 30m. Connect the two units by any kind of 2-conductor electrical wire as detailed on page number 2.
7 ML_RGT03_V5_english.doc
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. Now 25°C is supposed to be displayed by the control unit. If you read any other value, then set the difference as a P1 Tcorr value with opposite sign. (The procedure is detailed under Initial setup.) Return the control unit to normal operation, 25°C should be displayed. If correct, place the jumper of the heat sensor unit back to its original position to activate the real sensor instead of the reference resistor.
Important:
If an external heat sensor is connected, the jumper JP1 (next to the display) of the control unit must be placed in position 3 (closer to the display)!
