KNX TH65-AP thermal hygrometer

• Version: 27.01.2020 • Technical changes and errors excepted.

Dehumidification and/or humidification

Depending on the control mode, settings sections for humidification and dehumidifi-
cation will appear (stages 1/2).

For two-stage dehumidification, the setpoint difference between the two stages must
be defined, i.e. at which setpoint undercut the second stage is then added.

Determine the deviation from the setpoint at which the maximum variable value is
reached, i.e. the point at which maximum output is used.
The reset time shows how quickly the controller responds to deviations from the set-
point. In case of a short reset time, the control responds with a fast increase of the con-
trol variable. In case of a long reset time, the control responds somewhat less urgently
and needs longer until the necessary control variable for the setpoint deviation is
reached.
You should set the time appropriate for the humidification/dehumidification system at
this point (note manufacturer instructions).

Now specify what should be sent when the control is blocked.
On release, the control variable follows the rule again.

6.7.

Dewpoint

The

KNX TH65-AP thermal hygrometer

calculates the dewpoint and outputs the

value to the bus.

Setpoint difference between levels 1 and 2
in %

(for Level 2 only)

0...50; 10

Maximum control variable is reached
at target/actual difference of %

1...50; 5

Reset time in minutes

1...255; 3

When blocked, the control variable should

• not be sent
• send a specific value

Value in %
(

only if a value is sent)

0...100

Send pattern

• never
• periodically
• on change
• on change and periodically

On change of

(if sent on change)

0,1°C • 0,2°C • 0,5°C • 1,0°C • 2,0°C • 5,0°C

Send cycle

(if sent periodically)

5 s • 10 s • 30 s • 1 min • … • 2 h
