Description :

Span is the temperature difference, between which the thermostat operates and keeps the required setpoint temperature. 


For example, if you set a setpoint temperature of 20°C and the hysteresis setting is ± 0.5°C, your 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.


To activate the Span 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  TPI is displayed use the Arrow Buttons  to select Span.


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


  1. Using the arrow buttons again, scroll to select your desired Span hysteresis setting 0.5 or 0.25 , and press the tick to confirm the selection.


Using the arrow buttons  , scroll to select your desired Span hysteresis setting 0.5 or 0.25 , and press the 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 the Span Control Algorithm settings on your RT520 Series Thermostat.
