Temperature and Humidity Control
Item-No. 19 85 71 FOX-301A
Intended Use
The controller serves to record and display the temperature from -55 to +99.9°C and the relative air
humidity in a range from 0 to 100%. There are two programmable switching outputs available for the
temperature and the air humidity. This makes it possible to control cooling and heating processes or
ventilation systems or valves universally. The temperature and humidity is detected via an external
sensor. There is a bi-coloured display.
The control is only intended for installation in devices, displays or switching cabinets etc. and corre-
sponds to protection class 2 when installed (double or reinforced insulation). It may only be put into
operation after it has been installed. Use of the controller is permitted in devices of protection classes
1 and 2.
The device may only be installed by a specialist who is familiar with the relevant regulations and the
risks involved.
The device conforms to the CE standard and to the applicable European guidelines.
The device must not be used in potentially explosive environments, outdoors in the open air or in damp
interiors. Only the sensor may be exposed to measure the air humidity.
The device may not be used to safeguard persons, animals or machines.
The controller may only be operated with an alternating current of 100 to 240VDC/50-60 Hz. The stip-
ulated switching capacity must not be exceeded.
Operation under adverse ambient conditions is not permitted.
Unfavourable ambient conditions are:
• Dampness or excessive air humidity,
• Dust and flammable gases, vapours or solvents,
• Strong vibrations or magnetic fields.
Any use other than described above is not permitted and can damage the product. Furthermore, there
are dangers such as fire, short circuit, electric shock etc..
No part of the product must be modified or rebuilt!
The safety instructions must be observed unconditionally!

Installation

Prepare the installation surface in acc. with the installation measures.
The installation opening must be 68 mm x 68 mm.
Slide the enclosed rubber seal over the device from the connecting side to the display edge.
Insert the controller into the installation opening from the front.
Two fastening retainers are enclosed with the device. Place one on each side of the controller and slide
them towards the display until they reach the desired fastening degree. The controller is clamped into
place.
To remove it, press the two jagged flanks of the fastener together and pull the fasteners off the device.
Connection
The connection is illustrated as follows:
Screw terminal 1
Screw terminal 2
Screw terminal 3
Screw terminal 4
Screw terminal 5
Screw terminal 6
Screw terminal 7
Screw terminal 8
Screw terminal 9
Screw terminal 10
Screw terminal 11
Screw terminal 12
Screw terminal 13
Mount the sensor at the desired location. Make sure that the cable does not come into contact with any
moving parts or sharp edges. It could damage the insulation.
Re-check the device to make sure all connections are correct and all screw connections are tight.
Close the system into which the controller was installed and turn the power supply back on (automat-
ic cut-off, device switch, etc.).
Observe prior to connecting that all lines have no current. To do so, switch off the
electric cut-out and secure it against being switched on again.
