Upon connecting a GSM module, this is used to check the correct PIN code entry.
Example of using PT32 in connection with GSM module:
The thermostat is located in an object where anti-freeze temperature (e.g., 7 °C) must be kept.
1. Connect PT32 strictly according to the instructions.
2. Select the MANU mode.
3. Pushing the “ “ button and turning the “ “ , set the thermostat temperature to 7°C.
4. Before entering the object, enter the “Temp 23” SMS in your mobile phone, and send it to the module
number connected to the thermostat.
The thermostat receives the message and automatically switches the heating system on until the desired temperature
is achieved. Next, the PT32 automatically sends a RETURN SMS to inform you about the temperature change made.
Entering the object, you can adjust the temperature on the thermostat directly at will.
After connecting the GSM module according to the procedure on page 11, turn the “ “ button, the
following message appears on the LCD:

Note: If you choose YES and do not connect a module, the “GSM UNCONNECTED” notice appears on the LCD
