or moisture sensor to the control of the ventilation unit. The analogue signal of the sensor is interpreted as a control
signal for the rotational fan speed of the ventilation unit. When applying several sensors in a ventilation system, the
output signal of a maximum value module will be used to control the ventilation unit.
First, the navigation buttons (red text background) and check marks are used to select whether the sensor is
equipped with a power or voltage output (Electrical power: 4...20 mA, voltage: 0...10 V) and confirmed via Enter.
Then the lowest point (characteristic curve start value p1) and the highest point (characteristic curve end value p2) of
a characteristic curve assumed to be linear between these two points for the fan speed are parametrised between
17% and 100%. The nominal values (red text background) to be parametrised can be selected with the navigation
buttons and the values adjusted with the +/ - buttons.

Plausibility check for sensors with power output:
•
Concerns: Input A1 on the master controller (configured as 4...20 mA input)
• Error message if at the input a value of 0...3 mA is present for more than 1 s
•
Reset of the error if I > 3.5 mA for at least 1 s
4.3.2.5 Sub-menu Date/time
In this menu the date and time are set. The nominal values (red text background) to be parametrised can be selected
with the navigation buttons and the values adjusted with the +/ - buttons.
4.3.2.6 Sub-menu Language selection
In this menu, the local language for the TFT control panel can be selected via the navigation buttons.
4.3.2.7 Sub-menu Screen dimming
In this menu, individual screen brightness and the duration until the dimming takes effect after non-operation can be
adjusted using the navigation buttons.
•
Duration until dimming in 1 min increments
• Dimming in 5% increments
