37 Parameter setting

Sensor KNX VOC/TH-UP Touch • Version: 30.11.2021 • Technical changes and errors excepted.

Threshold value setting using a communication object:

Define, how the threshold value is to be received from the bus. Basically, a new value

can be received, or simply a command to increase or decrease.

During initial commissioning, a threshold value must be defined, which will be valid

until the first communication with a new threshold value. For units which have already

been taken into service, the last communicated threshold value can be used. Basically,

a humidity range is specified in which the threshold value can be changed (object value

limit).

A set threshold value will be retained until a new value or a change is transferred. The

current value is saved, so that it is retained in the event of a power supply failure and

will be available once the power supply is restored.

Set the hysteresis independent of the type of threshold value specification.

Switching output

Set the behaviour of the switching output when a threshold value is exceeded/under-

cut. The output switching delay can be set using objects or directly as a parameter.

Threshold value setting using Parameter • Communication objects

The value communicated last shall be

maintained

• never

• after power supply restoration

• after power supply restoration and

programming

Starting threshold value in 0.1% RH

valid until first communication

0 … 100; 70

Object value limit (min.) in 0.1%RH 0…100

Object value limit (max.) in 0.1%RH 0…100

Type of threshold value change Absolute value • Increase/Decrease

Increment

(upon increase/decrease change)

1,00% • 2,00% • 5,00% • 10,00%

Hysteresis of the threshold value in %

(relative to the threshold value)

0 … 50; 20

When the following conditions apply,

the output is

(TV = Threshold value)

• TV above = 1 | TV - hyst. below = 0

• TV above = 0 | TV - hyst. below = 1

• TV below = 1 |TV + hyst. above = 0

• TV below = 0 |TV + hyst. above = 1

Delays can be set via objects

(in seconds)

No • Yes

Switching delay from 0 to 1

(If delay can be set via objects:

valid until 1st communication)

None • 1 s • 2 s • 5 s • 10 s • … • 2 h

Switching delay from 1 to 0

(If delay can be set via objects:

valid until 1st communication)

None • 1 s • 2 s • 5 s • 10 s • … • 2 h
