Description :


Modern controls are designed to ensure that you get the best energy efficiency possible from your heating system. TPI (Time Proportional Integral) is an algorithm function in your room thermostat that ensures your boiler fires for the shortest possible time in order to reach and maintain your room at the comfort level selected. 


TPI regulation ensures economical system operation through more accurate temperature maintenance during the controlling process, and limits overshoot conditions. In addition to the exact and stable room temperature, the advantage of this system is the minimization of energy consumption and  therefore significant operation cost savings.


Similar to PWM ( Pulse Width Modulation), TPI works according to cycles. The cycle length is measured in Cycles per Hour.


The RT520 Series thermostats offer three types of TPI control: 

1. For Radiators (6 Cycles Per Hour )

2. For Underfloor Heating (3 Cycles Per Hour )

3. For Electric Heating (9 Cycles Per Hour )


To activate the TPI algorithm please follow this procedure.


  Procedure :


  1. Press one of the buttons to ‘wake’ the thermostat. The screen will illuminate.



  1. Press the COG  button (first of the buttons from the left) – SCHEDULE will be displayed.



  1. Using the Arrow buttons , scroll until CONTROL is displayed,  and press tick to enter the settings.



  1. Using the Arrow buttons  scroll until you see TPI or Span displayed


If Span is displayed use the Arrow Buttons  to select TPI.


  1. Once TPI is displayed on the screen, press the tick to enter the settings.



  1. Using the arrow buttons again, scroll to select the correct heating method being used ie. Radiators (TPI RAD), Underfloor Heating  (TPI UFH)  or  Electric Heating  (TPI ELEC), and press tick to confirm the selection.



Using the arrow buttons , scroll to select the correct heating method being used ie. Radiators (TPI RAD), Underfloor Heating  (TPI UFH)  or  Electric Heating  (TPI ELEC), and press tick to confirm the selection.



Using the arrow buttons , scroll to select the correct heating method being used ie. Radiators (TPI RAD), Underfloor Heating  (TPI UFH)  or  Electric Heating  (TPI ELEC), and press tick to confirm the selection.



  1. Your thermostat will return back to the previous Control Menu. Press the COG  button to exit this menu and return to the main temperature screen.



  1. This concludes the procedure for setting TPI on your RT520 Series Thermostat.
