1 Installation
1.1 Mounting
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the device from power supply
before opening the housing!
Note
Strong electromagnetic elds can impair the function of the device.
ÎMake sure the device as well as the system are not exposed to strong
electromagnetic elds.
The device must only be located in dry interior rooms.
The device must additionally be supplied from a double pole switch with contact
gap of at least 3 mm.
Please pay attention to separate routing of sensor cables and mains cables.
In order to mount the device to the wall, carry out the following steps:
ÎUnscrew the crosshead screw from the cover and remove it along with the
cover from the housing.
ÎMark the upper fastening point on the wall. Drill and fasten the enclosed wall
plug and screw leaving the head protruding.
ÎHang the housing from the upper fastening point and mark the lower fastening
point (centres 130 mm).
ÎInsert lower wall plug.
ÎFasten the housing to the wall with the lower fastening screws and tighten.
ÎCarry out the electrical wiring in accordance with the terminal allocation (see
page 4).
ÎPut the cover on the housing.
ÎAttach with the fastening screw.
1.2 Electrical connection
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the device from power supply
before opening the housing!
ATTENTION! ESD damage!
Electrostatic discharge can lead to damage to electronic com-
ponents!
ÎTake care to discharge properly before touching the
inside of the device! To do so, touch a grounded sur-
face such as a radiator or tap!
Note
Connecting the device to the power supply must always be the last step
of the installation!
Note:
It must be possible to disconnect the device from the mains at any time.
ÎInstall the mains plug so that it is accessible at any time.
ÎIf this is not possible, install a switch that can be accessed.
Do not use the device if it is visibly damaged!
ATTENTION! Extra-low voltage cables must not run together in a cable conduit
with cables carrying a voltage higher than 50 V.
ÎAlways route extra-low voltage cables and mains cables sep-
arately!
ÎPay attention to the local regulations!
The device is equipped with 2 relays in total, to which loads can be connected:
Semiconductor relay R1:
Conductor R1
Neutral conductor N (common terminal block)
Protective earth conductor ⏚(common terminal block)
Relay 2 is a potential-free extra-low voltage relay, e. g. for connection to a building
management system
Connect the temperature sensor to the terminals S1 and GND with either polarity.
The device is supplied with power via a mains cable.The power supply of the device
must be 100 … 240 V~ (50 … 60 Hz).

2 Function
The Central Outdoor Sensor detects the outdoor temperature and transmits this
value via the VBus®to the controllers connected.
If there is a sensor fault, the LED will ash, R1 will be energised and R2 switched off
(the potential-free contact will open).
LED ashing codes:
Permanent green: normal operation
Red ashing: sensor fault
Off: no power supply
