1 Use
Radio Frequency Repeater for INSTAT 868 r… (Room
temperature controller).
• Increases the distance of radio transmission
between INSTAT 868-r… RF-thermostats and
INSTAT 868-a… receivers.
• Improves the received signal quality of a receiver.
2 Features
• Amplifies the radio signal of INSTAT 868-r.. ther-
mostats
• 2 Repeater can be used in sequence
• The repeater inserts it self automatically into al-
ready existing radio links of the INSTAT 868 system.
• Only one repeater for many existing radio links
• Automatic working without any action from user
• Indication of received signal strength via 3 LEDs
• Indication of available mains power
• Can be directly inserted into a "SchuKo” socket
outlet
• Mains plug can be used furthermore
3 Functional description
The INSTAT 868-repS is an amplifier for RF signals.
The repeater repeats the received signals automati-
cally.
Only signals from INSTAT 868 transmitters will be
amplified.
3.1 Function of the Lamps
Lamp mains power available
No lamp no or very low signal
power (not enough
for repeating)
Lamp 1 low signal power
Lamp 2 good signal power
Lamp 3 very good signal
power
3.2 Installation
Plug the repeater in a socket outlet.
The Lamp will light up indicating that there
is mains power on the socket.
3 Lamps are indicating the received
signal strength.
The repeater now repeats the received signals auto-
matically.
There is no user action needed to add the device
into existing radio links.
The socket outlet of the device can be used further-
more.
3.3 Location
The Repeater should be located in a proper distance
from the transmitter
The right distance will be reached when lamps 2 or 3
are active.
Note: maximum 2 repeaters can work in sequence.
E.g. if the normal transmission distance in the
environment will be 30m, with the repeater this dis-
tance can be extended up to 90 m.
3.4 Testing the function
When lamps 2 or 3 are active, the device is working
properly.
The lamps are only active, if there is a radio signal. If
there is only one transmitter this will happen only all
10 minutes for a short period of time.
To force radio transmission:
Turn the temperature on the transmitter to maximum
value after some seconds there will be a transmis-
sion. After having done this turn the temperature to
minimum value for activating the next transmission.
This is working on all transmitters.
Note: After having finished the test set the tempera-
ture to the original value.
Specific actions to force transmission
INSTAT 868-r: Manually switching on/off the out-
put (see there 6.12)
INSTAT 868-r1: press Reset (below cover, see
there 5.1)
