   TPI (Time Proportional & Integral) is a self-learning, time- proportional algorithm. TPI type of regulation ensures economical 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).
3. Using UP or DOWN, select the TPI type you want to use.
   
5. Press SELECT to confirm.
   
   Span is the difference between the measured temperature and the set temperature.
