USING GSM MODULE (GST1 or GST2)
1) Mount and set the PT32 thermostat according to the instructions.
2) Set CONST12 to YES (use GSM); then, set CONST13 and CONST14 according to the instructions
on page 9.
3) Insert an activated SIM card in the GST1 (or GST2) module.
4) Interconnect the thermostat and GSM module with a data cable (delivered with GST1 or GST2).
Connect the GSM module power source to the 230 V / 50 Hz mains (the green LED lights up, and
the orange one is blinking on the module).
5) As soon as the orange diode lights up, test correct connection of CONST15 (see page 9: TEST) –
connection should always be established automatically within 3 minutes without the TEST function.
The PT32 thermostat can be controlled by means of a mobile phone by simply extending it by the GST1
or GST2 module (not included – must be purchased). For correct commissioning, the following proce-
dure must be followed:
