PLACE OF THE ASSEMBLY:
The wall unit must be placed at a height of approximately 1.2 to 1.5 m in a neutral place, i.e. to a
reference point for all rooms (heating circuit).
It is advisable to choose one of the inner partition walls of the coldest room of the stay during the day.
The wall unit must not be situated at following points
• in places with direct sunlight (taking into account seasonal changes)
• close to heat - generating devices such as TVs, refrigerators, wall lamps, radiators, etc.
• on the walls behind which heating pipelines or hot water pipelines are situated or if there are heated
chimneys
• on external walls
• in the corners of wall niches, racks or behind curtains (because of the insufficient air circulation)
• close to doors to unheated rooms (due to the influence of cold temperature)
ELECTRICAL CONNECTION
For the connection, use screened four-wire cable (two twisted pairs) with a cross-section of 0.2 to
0.75 mm
2
. One pair is used for the power supply, the other pair for data transfer. Connect the screening
on the side of the ACD03/ACD04 electronic controller to the PE protective terminal. On the side of
the room unit, leave the screening unconnected.
We recommend leading the cable separately from 230V conductors and other power lines (at least
5 cm)..
