Mixed air controller @@&name@@
Air circulation controller, normally influencing the supply air temperature. This does NOT switch to active mode, but is activated by a preceding controller if need be (e.g. preheater controller).
To implement a minimum ratio of outside air, the maximum value has to be limited, e.g. maximum value=75% corresponds to a minimum outside air ratio of 25%. Minimum and maximum values are active only with attached controller enabling (also if the controller is inactive).
The outside air temperature is compared with the ambient and/or exhaust air temperature and the favourable air according to heat or cold is used.
If the air circulation controller is not active (e.g. preheater has taken over), the flaps reverse the position if need be, when the supply/demand ratio changes.
If the free cooling is active, the air circulation shuts down (0%) and the exhaust air opens to 100%.
