Fan (Part 4)

The "DEHUM.SPEED" ➊ is entered as a

negative difference in % to the maximum

speed. This is the fan speed for the ﬁrst option

of dehumidiﬁcation.

The "UPS SPEED"

➋ is also entered as a

negative difference in % to the maximum

speed. When the controller receives a UPS

signal the controller will apply this reduced

speed for an emergency operation.

The parameters:

- control cycle ➌

- max. control correction ➍

- control factor ➎

are only necessary for the GEp-control,

which is explained in a separate manual.

If the cooling unit has low airﬂow during nomi

-

nal operation, the fan speed can be raised

when the temperature setpoint is exceeded.

The fan speed increase depends on the

temperature difference to the setpoint.

For this way of cooling the room by increas-

ing the fan speed you adjust a positive

temperature difference

➏ to the setpoint,

which represents the start point of the speed

increase.

Then you adjust a maximum speed

➑ for the

overload operation and another temperature

difference

➐ to the setpoint, which marks the

end of the proportional fan speed increase.

Having attained the second temperature

difference, the fan is operated with the

maximum speed for the overload operation.

This speed is kept even if the temperature

continues to rise.
