Safety Instruction

Caution:
This electronic device, which is looped into the connection lead, is intended for temperature control in dry and closed rooms only.
This device confirms to EN 60730, it works according operating principle 1C.
The circuit on which the unit is operated shall be protected by a miniature circuit breaker according to EN60898-1 (tripping characteristic B or C) with max. 10 A rated current.

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.
Do not insert a plug-in device.

Features

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 transition faults

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.

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.

Commissioning

Establish wireless connection

Note: Products delivered as set are already linked.
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:

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

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

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.

Faults
If a fault occurs, an alarm is triggered and an audible signal sounds.

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.

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.

Table 1: Function of the lamp and signal tone

Action	Lamp	Signal tone
No signal of thermostat without clock **	single blinking	single
No signal of thermostat with clock **	double blinking	single
Double addressing *	no significance	double

* 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 to check the reliability of operation at the specific location.
For testing the reliability of operation see 3.1.

Trouble shooting

Device will not switch on:
- Has wireless connection been established (refer to 4.1)?
- Refer to Table 2, Section 4 onward
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
Transmitter can not be learned in
- Run „delete wireless connection“ (see 4.2)
Reverse control action
- 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 blinks slowly
- For normal operation:
  Release button when control lamp is OFF
- Audible signal confirms successful setting

Table 2: If the device does not function, check the following:

Check	Yes	No
1 Is mains voltage available?	Continue with 2	Check fuse if necessary,

consult an electrician
2 Directly plug the heater into the wall outlet| Heater functions, continue with 3| Heater or connecting cable defective
3 Receiver:
Does the signal light flash?
Is the signal tone emitted?
(if necessary, wait for an hour)| Transmitter signal missing, continue with 4 (see 4.4)| Continue with 4
4 Transmitter: Is the battery OK?| Continue with 5| Insert new batteries, continue with 5
5 Transmitter: set to 30 °C Does the device switch on after approx. 30 s?| Continue with 6| Device was already switched on, continue with 6 Or if transmitter signal is missing, continue with 7
6 Transmitter: set to 5 °C Does the device switch off after approx 30 s?| Function OK| Transmitter signal is missing, continue with 7
7 Relearn the connection to the receiver Repeat Sections 5 or 6 and check if it works now.| Function OK| Continue with 8
If applicable, check transmission range, refer to 3.1 “Testing the transmission range”
8 Reduce distance between transmitter and receiver to approx. 2 m Repeat Sections 5 or 6 and check if it works now.| Transmitter and receiver work properly| Transmitter or receiver defective
