7.2.1
Exhaustair rate
Exhaustair rate
Exhaustair rate
Percentage share of the stall in the total exhaust air system.
In central exhaust air systems the total exhaust air is determined from the sum of the
exhaust air percentages of all stalls.
This setting is possible for information in all single exhaust air systems. The exhaust air
total of the system is displayed in the Quickinfo menu.
Adjustment range: 0.0 - 100.0 %
Factory setting: 10.0 %
7.2.2
Minimum speed cut off
Msco
Minimum speed cut off
In some cases in which minimum air ventilation is not needed, this feature can be used
to prevent an undercooling of the room.
Msco. = OFF
(factory setting).
•
If no
“
Minimal ventilation
”
is set, the fan comes to a standstill on reaching the
setpoint, the shutter is fully closed in central exhaust air systems.
•
If a
“
Minimal ventilation
”
is set (e.g. 20 %), the fan is not switched off, the shutter is
never completely closed in central exhaust air systems, i.e. a minimum ventilation is
always ensured (fan does not fall below the
“
Minimal ventilation
”
setting).
MSCO value
For "minimum air switch-of = On2 takes place a disconnection from setting 2minimal
ventilation" to "0", if the given difference is reached related to the Setpoint.
•
At a plus value (+) before reaching the desired value
•
At a minus value (-) after falling below the desired value.
•
Setting range: -10...+10 K
•
Factory setting: -5.0 K
