Air Humidity Control
Version 02/06
Item-No.. 19 85 32 FOX-1H °
Intended use
The air humidity control serves to detect and display the relative air humidity in a
range from 20 to 99%. A programmable, potential-free switching output is available.
This makes it possible to control ventilation systems or valves universally. The
humidity is detected via an external sensor. The display colour is red.
The air humidity control is only intended for installation in devices, displays or
switching cabinets etc. and corresponds to protection class 2 when installed (dou-
ble or reinforced insulation). It may only be put into operation when installed. This
control may be operated in devices of protection class 1 and 2.
Installation work must only be carried out by suitably qualified personnel who are
familiar with the hazards involved and with the relevant regulations.
The device is CE conform and meets the respective European directives.
The device must not be used in hazardous locations, damp interiors or outdoors in
the open air. Only the sensor may be exposed to measure the air humidity.
The device may not be used to safeguard persons, animals or machines.
The air humidity controller may only be operated with an alternating current of
230VDC/50-60 Hz. The maximum input volume may not be exceeded.
Operation is not permitted under unfavourable ambient conditions.
Unfavourable ambient conditions include:
•wetness or excessive humidity
•dust or combustible gases, vapours or solvents
•strong vibrations or magnetic fields.
Uses other than those described above are not permitted. They will lead to damage
to the product. Additionally misuse may lead to short circuiting, fire, electrical
shocks etc.
No part of the product must be modified or converted!
The safety instructions should be observed without fail!

Installation
Prepare the installation surface in acc. with the installation measures.
The installation opening must be 71 x 29 mm.
Slide the enclosed rubber seal from the connection side to the display frame across
the device.
Insert the controller into the installation opening from the front.
Two attachments are enclosed to the device. Place these lateral on the controller
and slide it towards the display up to the desired attachment degree. The controller
is fixed in place.
To loosen it, press the two spiky sides of the attachment together and pull the
attachment off the device.
Connection example
The connection is illustrated as follows:
Screw clamp 1 Sensor connection black cord (+)
Screw clamp 2 Sensor connection white cord (IN)
Screw clamp 3 Sensor connection yellow cord (-)
Screw clamp 8 Opening contact (to the consumer)
Screw clamp 9 Switching contact (230V~, L1)
Screw clamp 10 Closing contact (to the consumer)
Screw clamp 11 Mains connection (230V~, N)
Screw clamp 12 Mains connection (230V~, L1 phase)
Attach the sensor on the desired position. Make sure that the cable does not come
into contact with rotating parts or sharp edges.
Check the device once again for the right connection and tight screw connections.
Close the system into which the controller was installed and turn the power supply
back on (automatic cutoff, device switch, etc.).

If consumers of protection class 1 are connected, the protective con-
ductor must be connected separately and properly.
Do not install the sensor cable next to signal or net cables.
Taking the Device into Operation and Using it

To ensure correct initial operation, please read these operating
instructions and the safety instructions carefully before using the
appliance!
The controller does not have a main switch and turns on automatically when the
operating voltage is activated.
A short self-test takes place after activation. The display switches to normal opera-
tion in approx. 1-2 seconds and shows the current relative air humidity in percent.
Programming the controller is very easy and takes place via three buttons on the
display field. The operation is divided into two parts:
•The setup mode
Here you can set threshold limits. The setup mode enables changing the humidi-
ty limit without complicated programming steps.
•The programming mode
Here is where you set the basic parameters. To access this mode, press the but-
ton „Set“ (D) for approx. 5 seconds.
General
By pressing the programming button „SET“ (D), the corresponding menu is called
up or switches to the next programming step. The parameters that can be set up
blink.
The two arrow buttons (A/B) serve to change the parameters.
The set or programming mode is terminated if you do not press a button within 10
seconds or keep the button „Set“ (D) depressed for approx. two seconds. The dis-
play shows „o-k“. The parameters are saved and also remain saved after turning
the device off.
The following program sketches show the individual setup and programming steps.

Maintenance and Cleaning
The product requires no servicing on your part apart from occasional cleaning.
Periodically check the technical safety of the device.
It can be assumed that risk-free operation is no longer possible if:
•there is visible damage to the device or to the connections,
•the appliance has been stored under unfavourable conditions for a longer period
of time
•the device has been subjected to heavy transport strain.
Error messages
The device detects errors in the system and the sensor itself and shows these on
the display.
The following error messages are possible:
ErI Memory error. Turn the power of the device off and turn it on again. If
the error message persists, please send the device to the retailer’s
customer service.
0-E Sensor error. The sensor is interrupted. Check the cable.
S-E Sensor error. The sensor is short-circuited. Check the cable.
Err Sensor error. The sensor itself is defect. Exchange the sensor.
The outside of the appliance should be cleaned with a clean dry cloth or brush only.
Do not use abrasive or chemical cleaning agents which could damage the housing
or impair operation.
Disposal
Old electronic devices are hazardous waste and should not be disposed of
in household waste. When the device has become unusable, dispose of it
in accordance with the current statutory regulations.
