1 Use
Radio frequency receiver for INSTAT+ 868-r (Room
temperature controller with clock) or INSTAT+ 868-
r1 (Room temperature controller without clock).
For switching electrical devices such as:
• Electric radiators
• Electric wall-mounted heating systems
• Electric towel dryers
Caution: Do not plug multiple receivers in a
cascade!

• Can be directly inserted into a wall socket outlet
• Switches up to 10 A
• One transmitter can control several receivers
• Self-leaning address tuning through “Learning
Mode” in the transmitter
• One touch button for selecting functions
• Signal lamp indicates faults
• Monitoring of valid radio link
• Acoustic signal in the event of failure
• Emergency operation in case of transmition
faults
3 Functional description
The INSTAT 868-a1S receiver converts the transmis-
sion signals of the INSTAT 868-r… transmitters into
control signals for electrical devices. The devices are
switched via this receiver.
3.1 Testing the transmission range
To determine the radio link range, proceed as follows:
Continuously set 30 °C and 5 °C on the transmitter;
the receiver will switch on and o. If the receiver
stops to switch, the radio link range has been
exceeded.
4 Commissioning
4.1 Establish wireless connection
Note: Products delivered as set are already lin-
ked. For test perform “Testing the radio range”
3.1
To make the receiver work properly, a connection
must be established to the transmitter. Follow the
steps below:
a) On the transmitter, switch to “Learning mode”
(see transmitter operating instructions)
b) On the receiver activate the “Learning mode” as
follows:
Briey press the button, short signal tone, lamp
is blinking.
When the transmitter has been recognised,
short signal tone, signal lamp goes o.
For thermostats without clock: 2 x blinking
For thermostats with clock: 4 x blinking
c) On the transmitter, terminate the “Learning
mode”.
d) For testing the wireless connection just establis-
hed, see 3.1.
Note: Before learning again a transmitter “Deleting
radio links” has to be carried out see 4.2. After that
the connections can be re-learned.
4.2 Deleting a radio link
The conection between transmitter and receiver
will be deleted.
• Press the button for 5 seconds
(there is a short beep, light ashes)
After 5 seconds, a short signal tone. The lamp
expires
• Release button.
4.3 Power failure
In the event of a power failure in the transmitter or in
the receiver, all data will be preserved. When voltage
is available again, normal operation will continue.
4.4 Faults
If a fault occurs, an alarm is triggered and an audible
signal sounds.
4.4.1 Double addressing
2 transmitters transmit with the same address.
A dual audible signal sounds as a warning.
Control lamp blinks – see Table 1.
To cancel the alarm, re-program the transmitter.
4.4.2 Loss of transmission signal
If the transmitter fails to receive an actuating signal
for more than 1 hour, emergency mode will be
triggered.
Once the actuating signal is restored, the emergen-
cy mode will be cancelled automatically.

Note:
In some rare cases it may not be possible to
establish a permanent radio link between the
radio transmitter and the radio receiver. We
therefore recommend to check the reliability of
operation at the specic location.
For testing the reliability of operation see 3.1
4.5 Trouble shooting
1.
Device will not switch on:
 Has wireless connection been established
(refer to 4.1)?
 Refer to Table 2, Section 4 onward
2.
It beeps
 for general information see 4.4
 two transmitter transmit with same address,
see 4.4.1!
 No wireless connection, see table 2, Section
6.
3.
Transmitter can not be learned in
 Run „delete wireless connection“ see 4.2
4.
Reverse control action
 To re-set to normal operation
• Push button briey, short audible signal, cont-
rol lamp blinks
• Push and hold button pushed
after 5 seconds, a short audible signal will
sound, control lamp will blinks slowly
• For normal operation:
Release button when control lamp is OFF
• Audible signal conrms successful setting
