Access has a year-based clock function. This means that a week schedule with holiday periods for a full year can be set.

There are daily individual schedules for low speed, normal speed and high speed of the fan, each with up to two running periods.


Access also has four additional schedules (extra time channel 1...4) with two running periods each for controlling custom equipment via digital outputs.

Extra time channel 4 also can also serves as a schedule for the recirculation function.


Should periods for the different speeds and recirculation overlap, the schedules are prioritized in the following order (highest to lowest):


  1. High speed
  2. Normal speed
  3. Low speed
  4. Recirculation


The default schedule for the normal fan speed is set for a single run period (8:00 - 17:00) for every working day.

This means that the air handling unit will start operation at 8:00 and will stop at 17:00.


Running periods with matching start & stop times (0:00 - 0:00) are considered as inactive.


For 24 hour running the period should be set 0:00 - 24:00.


If it is required to run the unit from one day to another, the desired running time for both days must be entered.


e.g. from Monday 22:00 to Tuesday 09:00:

Monday:        22:00 - 24:00

Tuesday:        0:00 - 9:00
