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!

2 Features

• Can be directly inserted into a wall socket outlet
• Switches up to 10 A
• One transmitter can control several receivers
• Self-learning 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 transmission faults

3 Functional Description

The INSTAT 868-a1S receiver converts the transmission 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 off. If the receiver stops to switch, the radio link range has been exceeded.

4 Commissioning

4.1 Establish wireless connection

? Note: Products delivered as a set are already linked. For test, perform “Testing the radio range” (Section 3.1).

To make the receiver work properly, a connection must be established to the transmitter. Follow the steps below:

1. On the transmitter, switch to “Learning mode” (see transmitter operating instructions).
2. On the receiver, activate the “Learning mode” as follows: Briefly press the button, short signal tone [?], lamp is blinking [?]. When the transmitter is recognized, short signal tone [?], signal lamp goes off [⚫].
   • For thermostats without clock: 2 x blinking [??]
   • For thermostats with clock: 4 x blinking [????]
3. On the transmitter, terminate the “Learning mode”.
4. For testing the wireless connection just established, see Section 3.1.

? Note: Before learning a transmitter again, “Deleting radio links” (Section 4.2) must be carried out. After that, the connections can be re-learned.

4.2 Deleting a radio link

The connection between transmitter and receiver will be deleted.

• Press the button for 5 seconds (there is a short beep [?], light flashes [?]). 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, reprogram 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 emergency mode will be cancelled automatically.

* No emergency mode.

** Emergency mode:

• Signal tone appears [?], lamp is blinking [?].
• Starting off with 30% energy (3 Min on, 7 Min off).

? 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 checking the reliability of operation at the specific location. For testing the radio range, see Section 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 transmitters transmit with the same address, see 4.4.1!
   • No wireless connection, see Table 2, Section 6.
3. Transmitter cannot be learned in:
   • Run “Delete wireless connection”, see 4.2.
4. Reverse control action:

   To reset to normal operation:

   • Push button briefly, short audible signal [?], control lamp blinks [?].
   • Push and hold button pushed. After 5 seconds, a short audible signal [?] will sound, control lamp will blink slowly [?...].
   • For normal operation: Release button when control lamp is OFF [⚫].
   • Audible signal [?] confirms successful setting.
