External correction of the temperature set point
The set point can be changed at the set point correction switch or by a potentiometer con-
nected to input F8. The potentiometer F8 and the set point correction switch both have an ef-
fect on the temperature set points.
The set point is changed at the correction switch in ±1 °C steps from one to the next switch
position.
A correction is possible in the range from –5 °C (potentiometer setting 1000
Ω
) to +5 °C
(potentiometer setting 2000
Ω
) provided the supply air temperature limitation in a supply air
temperature control permits it.

External setting of the outdoor air rate
The outdoor air rate can be determined at the input F9 with a potentiometer. The outdoor air
rate is then determined between the value
Minimum outdoor air rate (potentiometer setting
1000
Ω
) and 100 % (potentiometer setting 2000
Ω
).

External correction of the humidity set point
In all air-conditioning systems, the humidity set point can be determined at the input F9 with
a potentiometer. The humidity set point is then determined between –20 % rH (potentiometer
setting 1000
Ω
) and + 20 % rH (potentiometer setting 2000
Ω
), provided the supply air limit
and supply air humidity control allow it.
