value.
Span is the temperature difference, between which thermostat operates and keeps
setpoint temperature. For example, if you set setpoint temperature to 20°C and if the
hysteresis is ± 0.5°C, heating will be turned on when the room temperature drops to
19.5°C and turned off when the room temperature reaches 20.5°C.

, select the TPI type you want to use.
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. RT520RF offers 3 types
of TPI control: 1. for radiator (6CPH); 2. for underfloor heating (3CPH); 3. for electric
heating (9CPH).
