option excludes the other.  
If you bought the RT520TX and RXRT520 separately or if you want to re-pair thermostat with the  
receiver, make sure that the device is disconnected from the power supply and the switches on the  
receiver have been set to AUTO and ON. Then connect the receiver to the power supply and wait for  
the red LED to light steadily. Then switch to the OFF position and again to ON position quickly. The red  
flashing LED will confirm entering the pairing mode.

system operation through more accurate temperature maintenance  
during controlling process and limits overload conditions. In addition  
to the exact and stable room temperature, the advantage of this  
system is the minimization of energy consumption and significant  
savings. RT520 offers 3 types of TPI control: 1. for radiator (6CPH); 2.  
for underfloor heating (3CPH); 3. for electric heating (9CPH).
