4.3
Outdoor installation
Outdoor installation is possible up to -20
°
C when the controller supply is not switched off. Installation
must be protected from the effects of weather as much as possible, including protection from direct
sunlight!
4.4
Installation location for agriculture
When using for animal keeping, do not install the device directly in the stable but in a separate room
with a lower pollutant load. This helps to avoid damages caused by pollutant gases (e.g. ammonia
fumes, hydrogen sulphide fumes).
4.5
Temperature in
fl
uences during commissioning
Avoid condensation in the controller and functional faults attributable to condensation by storing the
controller at room temperature!
4.6
Mounting the two fresh air temperature sensors type TFR
Please note the following when mounting the two sensors to measure the supply air temperature:
1. Mount the sensors as far apart as possible, whereby the temperature difference between the
two measuring points should be as low as possible.
2. To avoid extreme temperature peaks, these are not mounted outdoors unprotected but in the
ante-room through which the fresh air is usually drawn.

Safety precautions
Danger due to electric current
•
Work on electric components may only be carried out by trained electricians or by persons
instructed in electricity under the supervision of an electrician in accordance with electrical
engineering regulations.
•
The 5 electrical safety rules must be observed!
•
It is forbidden to carry out work on electrically live parts.
•
Other measures may be necessary to achieve safe electrical isolation.
•
A second person must always be present when working on energized parts or lines who discon-
nects in case of emergency.
•
Inspect electrical equipment periodically: retighten loose connections
–
immediately replace dam-
aged lines and cables.
•
Always keep switch cabinets and all electrical supply facilities locked. Access is only allowed for
authorized persons using a key or special tool.
•
Operating the device with the housing cover removed is prohibited because energized, exposed
parts are present inside the device. Disregarding this regulation can lead to severe personal injury.
•
The device owner is responsible for the EMC of the entire plant according to the locally applicable
standards.
•
Never clean electrical equipment with water or similar liquids.
