Parameters / Function description
The "Night ventilation minimum outside temperature"
parameter sets the minimum outside temperature below
which night ventilation is disabled.
The P component for HR determines how sharply the output
signal of the HR damper is modified in proportion to a control
deviation.
If the P component is set low, the control unit responds more
quickly.
If the P component is set high, the control unit responds more
slowly.
The integral action time for HR determines how great the
time effect is on the output signal of the HR damper due to a
control deviation.
If the integral action time is set low (high time effect), shorter
correction times result. However, this also means greater
fluctuations around the set value. If the integral action time
is set high, longer correction times result This also means
lesser fluctuations around the set value.
If the system is equipped with an air quality sensor / CO
sensor, this parameter must be set to ON in order to make
this function available.
If air quality control is enabled, this parameter defines the
default value from which the speed is increased.
If air quality control is enabled, this parameter defines the
default value at which the maximum speed is reached.
Observe compliance with the limits set by parameters LM015,
LM016.
