Min. exhaust air
6.4.2.9 Min. exhaust air
The min. exhaust air function can be used whenever the
exhaust air temperature is not permitted to be below a
predetermined value.
The function controls the heat exchanger rotor speed (efficiency)
in order to limit the exhaust air temperature to the required
value. The function decelerates the heat exchanger rotor speed
from the current level, until the exhaust air temperature reaches
the preset minimum permissible setting.
Exhaust air regulation requires a separateTBLZ-1-58-aa tempera-
ture sensor (accessory) fitted in the AHU's exhaust air.
See separate installation instructions for the TBLZ-1-58-aa Inter-
nal temperature sensor.

Cooling
HX (heat exchanger):
The temperature efficiency of the air handling unit’s heat
exchanger is modulated to provide max. cool recovery.
Cooling Boost (Economy):
Involves increasing the supply air and extract air airflows to
convey more cooling energy to the premises. The flow increase
takes place between the current flow and the preset max. flow.
Extra regulation sequence:
Used in the cooling mode for air cooler (if required), etc.
ReCO
2
:
Recirculated air is variably mixed in up to the lowest permissible
supply airflow. Assumes inclusion of the TCBR air recirculation
section accessory.
Cooling:
Air cooler provides cooling capacity.
