Linearly
.
MaxAiring
determines at what temperature the minimum amount of fresh air will be 100%.
MinAiring
determines at what temperature the minimum amount of fresh air will be.
Between these cut-off temperatures, the amount of fresh air will vary linearly. These
values can be set separately for both states of
Heat
and
Cool
.
In the
Ventilate
state, the
mixing setting remains the same as in the previous regime.
Setpoint
– with this option, the mixing damper acts as a heating or cooling component and
must be assigned a priority for heating or cooling. The amount of fresh air is controlled based
on PID control.
PID–Regulation
–
the factory default values are:
TI = 150 s, KP = 8, TD = 0 s.
MinFreshAirComf
,
MinFreshAirRedu
(0%, 15%)
– minimum hygienic value of supply air
damper opening for every regime. This parameter does not apply if the unit is in its
Off
regime. The supply and exhaust dampers are always opened to at least this value when the
unit is running, if the mixing regime is selected.
StartFreshAir
(15%)
– indicates the amount of fresh air when the unit starts. Unit start is
signalled as an auxiliary regime.
Defrost
(
No
/
Yes
)
– affects the amount of fresh air when defrosting any of the configured
components.
No
– defrost status of a component does not affect the amount of fresh air.
Yes
– reduces the amount of fresh air to the minimum value when defrosting some
component.
