OPERATION & CONTROL
Ventilation Unit RT 250/400S-EC-RS
2. Fan control
In the operating menu you can set which mode the fans should run in. You can also see if the fans are running at
fixed speed or variable. You can also see current values and setpoints. The set values are seen within
parentheses.
Fan control
In the fan control the following six modes are always available:
·
Auto: The most optimal mode. This automatically controls the temperature acc. to the built-in and
optimized algorithms of the system.
·
Min flow: This forces the system to run with the set minimum flow.
·
Boost: This forces the system to boost the flow. Useful if you, for example, quickly would like to air out.
·
Max flow: When the fan runs with the set maximum flow.
·
Kitchen flow: Used while the cooker fan is used. During kitchen flow the supply air fan normally has a
higher flow than the exhaust air fan to compensate for the air that the cooker fan extracts.
·
Off: In this mode all fans are off.
The following three modes are available if the feature is installed and configured. Even if the feature is not
configured, it is visible and can be selected, but the system will after a few seconds revert to the previous
selection.
·
Stove: Used when a stove is being used. In the stove mode normally the supply air fan has a higher flow
than the exhaust air fan to compensate for the air that the stove extracts.
·
ECO: Only used with room control or exhaust air control when you are not home. The fans go down to
minimum flow but are gradually increasing to normal flow based on heating or cooling needs. ECO
adjust gives a temperature range around the setpoint where neither heating nor cooling is active.
·
Fire: Not used on this unit!
