The unit operates on a 60-minute cycle. For the first 40 minutes, the unit recirculates air or is off (See configuration parameter 2 in Section 2.3.3). For the last 20 minutes, it exchanges air. However, if the outdoor temperature* is too high or too low (see configuration parameters 3 and 4 in Section 2.3.3), the unit recirculates air during the last 20 minutes.

*The outdoor temperature reading is taken from the unit FRESH AIR FROM OUTSIDE port; due to the lenght of the insulated duct, the reading is slightly different from the real outside temperature.
