- P21Error code- Low voltage input Activation delay for the bathroom switch (to switch to high position). • 'x' minutes after operating the bathroom switch, the ComfoAir switches to the HIGH SETTING
- P22Error code- Low voltage input Deactivation delay for the bathroom switch (to switch to normal posi- tion). • 'x' minutes after operating the bathroom switch, the ComfoAir switches back to the NORMAL SET- TING
- P23Error codeDeactivation delay for ventilation position 3. • If ventilation setting 3 (high) is switched on briefl y (< 3 sec), the ComfoAir remains at ventilation setting 3 in accordance with the time set in this menu. If the position switch or RF remote control is operated during this lag- ging time, the ComfoAir will instantly revert to the ventilation position as set at that time
- P25Error codeOverrun timer for ventilation setting 3 (using ). After pressing briefly (< 2 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
- P26Error codeOverrun timer for ventilation setting 3 (using ). After pressing continously (> 2 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
- P27Error codeTime for the boost setting. After pressing on the CC Luxe** or after turning on the PARTY TIMER on the ComfoSense, 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
- P29Error codeSetting the ComfoHood** ventilation levels. When the ComfoHood** is switched on the ComfoHood** ventilation settings can be set x-% higher than the corresponding ‘normal’ ventilation levels

- P32Error codeSetting the capacity (in %) of the exhaust fan in MEDIUM POSITION
- P33Error codeSetting the capacity (in %) of theexhaust fan to HIGH
- P34Error codeSetting the capacity (in %) of thesupply fan to ABSENT
- P35Error codeSetting the capacity (in %) of the supply fan in LOW LEVEL MODE
- P36Error codeSetting the capacity (in %) of the supply fan in MEDIUM LEVEL MODE
- P37Error codeSetting the capacity (in %) of the supply fan in HIGH LEVEL MODE
