The temperature controller compares the temperature acquired by the sensor against the actual setpoint. In case of a deviation, the controller adjusts the heating or cooling while actual setpoint is reached.


Access has a choice of the following temperature control modes:


  1. Supply air - the supply air temperature will be constantly kept at the user setpoint value.
  2. Supply air outdoor compensated - the supply air temperature setpoint is adjusted depending on the outdoor temperature.
  3. Room cascade - the supply air is controlled as part of a cascade controller together with the room temperature controller. The room temperature offset will dictate the supply air temperature setpoint.
  4. Extract air cascade - the supply air is controlled as part of a cascade controller together with the extract temperature controller. The extract temperature offset will dictate the supply air temperature setpoint.
  5. Room (summer) else outdoor compensated supply air - combination of modes 2 and 3 with summer/winter switch.
  6. Extract air (summer) else outdoor compensated supply air - combination of modes 2 and 4 with summer/winter switch.
  7. Room outdoor compensated - same as mode 3 with outdoor air temperature dependency added.
  8. Extract air outdoor compensated - same as mode 4 with outdoor air temperature dependency added.
  9. Extract air dependent supply air - supply air temperature setpoint follows extract air temperature with settable difference.
