Overrun timer for ventilation position 3 (using a hardwired 3-position switch). ■ If ventilation setting 3 (high) is switched on briefly (< 3 sec), the unit will switch to the high setting for ‘x’ minutes and then automatically returns to the normal setting. If any switch is operated during this lagging time the unit will instantly revert to the ventilation position as set at that time
