Fan control  

Five modes are always available:  

·

 

Auto:  gives you an optimized function.  The temperature is automatically controlled in accordance with 
the unit's internal and optimized algorithms. 

·

 

Min. flow:  The system is forced to use a set minimum air flow.  

·

 

Boost flow: The system is forced to boost the air flow.  Useful for example if you need to air the building 
very fast. 

·

 

Max. flow:  The system works at set maximum air flow.  

·

 

Off:  All fans are switched off. 
 

Four other modes are available if those functions are installed and configured. (It is possible to choose these 
modes even if the function is not configured, but the system will return to earlier choice after a few seconds. 

·

 

Stove: This mode should be used when the stove/fireplace is used.  The supply air fan works at a higher 
speed than the exhaust air fan, to compensate for the air the stove extracts. The cooling is disabled for a 
while after the stove/fireplace has been used, in order to retain the good stove heat. 

·

 

Kitchen:  Use this mode when the cooker fan is running. The supply air fan works at a higher speed than 
the exhaust air fan, to compensate for the air the cooker fan extracts.   

·

 

ECO:  Suitable to use when no one is at home.  The fans switch to minimum flow, but gradually  
increase to normal flow when there is need for higher or lower temperature. ECO-adjust gives a 
temperature range around the setpoint and neither heat nor cool is enabled.

 

·

 

Fire: To be used above all when testing the fire function.  The supply air fan stops at the same time as 
the exhaust air fan works at its maximum speed. 

 
 

Timer settings 

 

The clock and summer/winter time 

The clock can be set and the change between summer and winter time can be made automatic.  

Enable timer 

The timer is enabled upon delivery and connected to the function Min flow. If the timer is disabled, so are preset 
times and holiday schedules. 

Time schedule 

Two periods a day may be set. Note! To enable the timer from, for example Monday 20:00 until Tuesday 06:00 
the settings should be Monday Per 2: 20:00 

– 24:00 and Tuesday Per 1: 00:00 – 06:00. 

To repeat the same time every day of the week, use the function Monday 

Ú

 Friday. 

If you want the same time on Saturdays, Sundays and all holidays (specified in holiday settings), use the macro 
function Saturday 

Ú

 Holiday. 

There is a separate menu for holiday schedules.  

Holiday schedule 

Up to 24 separate holiday periods for a complete year may be programmed. A holiday period may consist of a 
succession of days, from 1 to 365. The date is written: MM:DD. (It is important to set the time period from 00:00 
one day until 00:00 next day. For example holiday June 6 will be written 06:06 

– 06:07.) If that particular day falls 

during a holiday period, the system will use the schedule for 

“Holiday”.
