5.1 Establishing the radio link

On completion of the installation work, a link between

the INSTAT 868-r… transmitter and the radio receiver

must be established. To do this, follow this: (see g. 1)

a) Set the transmitter to “Learning mode” (see

Operating instructions for transmitter)

b. For function-1, – switching mode –

activate “Learning mode” on transmitter (A) to do

this: press the button brieyz

A signal tone sounds, the signal lamp lights up

and the output is switched on briey. When the

transmitter is recognised, the signal tone ceases to

sound and the signal lamp extinguishes.

c. Terminate the “Learning mode” on the transmitter

d. Test the radio links which have just been established

(see below picture 3 and Table 1))

3. Function description

The INSTAT 868-a1 receiver converts radio signals

received from a transmitter, e.g. INSTAT 868-r … into

control signals for loads. The loads are switched by

means of a relay.

The switching state of the output is indicated by a

signal lamp.

For switching characteristics, see Installation instruc-

tions for the transmitter under item “Function descripti-

on”. For controlling the electric loads, the output can be

congured in dierent ways.

3.1 Basic Functions

3.1.1 Function - 1, - switching mode -

“One transmitter controls one switching

output”

One transmitter controls the output for heating/cooling

ON/OFF.

This function is active, if jumper BR1 is closed.

Note: For heating systems, which are in stand by mode

during summer time (e.g. electric heating), the valve

protection has to be switched o (in the transmitter).

If the valve protection is not switched o, a daily 3min.

heating will take place.

3.1.2 Reversing the control action

The switching characteristics of the output and the

signal lamp are reversed in respect of all functions

(also pump control). Due to this feature, the following

functions can be implemented.

• connecting actuators NO

• changing from summer to winter mode

(cooling instead of heating)

For cooling (summer mode) or actuators NO:

single-pole plugging of J1 jumper (One-pole plugging

prevents loss of jumper)

For heating (winter mode or actuators NC)

(= as delivered condition)

double-pole plugging J1 jumper .

3.1.3 Testing the radio link range

To determine the radio link range, follow this:

Set the transmitter to “Learning mode”:

1. Press the z button and the ”Reset” button simulta-

neously

2. Release the ”Reset” button rst, then the z button

The signal lamp lights up. The signal tone and the

output operate in the switching mode, approx.

2 sec. ON, 8 sec. OFF.

3. Now, while holding the transmitter in your hand,

walk away from the receiver until you reach the point

where the signal tone is no longer audible and the

signal lamp stops ashing. This point is the maximum

possible radio link range.

4. Always terminate this function by pressing the “Reset”

button.

5. Quit the “Learning mode” on the transmitter

As far as a free transmitter is used, existing radio links

will not be aected.

3.1.4 System demonstration

To demonstrate the radio range, see section 3.1.3

“Testing the radio link range”. If necessary, a lamp can

be connected to the output.

3.1.5 Signal lamp function

The signal lamps provide the following information:

• Output state … ON/OFF in a interval of 10 min.

or steady light may be possible

• Faults … Blinking; Duration varies

depending on type of fault

• Learning mode … ON until the link is established

or the Reset button is pressed

• Valve test … ON as long as the “Reset” is

pressed

• Testing the

radio link range … Flashing, 10 sec. interval

• Monitoring of

channels … after “Reset”

3.1.6 Jumper function

J1: open to reverse control action = cooling

J2: open to switch o the beeper

BR1: closed = only switching mode possible

open = all functions possible

One-pole plugging prevents loss of jumpers

3.2 Enhanced Functions

The functions

• pump logic control

• Time switch (Maser/Slave)

• pilote output

are described in the additional manual „Enhanced

functions for 1 channel receiver INSTAT 868-a1, no.

468931003281.

These functions are available by opening Jumper BR1.

Note

In some rare cases it may not be possible to esta-

blish 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. In order to establish longer

transmission distances (up to 90 m) or in case of

critical locations, the RF repeater INSTAT 868-rep

can be used.

The signal tone sounds

After releasing the button, the “Reset” button must z

be pressed within 10 seconds. As a result of this, the

signal lamp extinguishes and the signal tone ceases to

sound. After 10 seconds, the “Learning mode” starts; a

link would be established to a transmitter which hap-

pens to be in the “Learning mode”.

5.3 Quitting/Reset

To – quit the “Learning mode”

– acknowledge a failure or

– terminate the Radio link range test or

– terminate the valve test

– in the event of any other inexplicable phenomena

push the “Reset” button. This restores the output to its

initial state (also reversed control action). When new

actuating signals are received (possibly after 10-20

min.), the output will return to its previous state. Any

existing radio link will be maintained.

**) Will be complied with, if the radio receiver is

installed on a level, non-conducting surface.

5.4 Power failure

If there is a power failure in the transmitter or in

the receiver, all data is saved. When power supply is

restored, normal operation is resumed.

5.5 Faults

If faults occur, an alarm is triggered. In this case, the

signal lamp ashes with varying duration, if necessary,

a signal tone sounds.

5.5.1 Double addressing

In this case, the signal lamp shows continuous double

ashing. It is cancelled by reprogramming one of the

transmitters. The signal tone sounds.

5.5.2 Short time losses of the transmission

signal

If the transmitter fails to receive an actuating signal

within a period of 1 and up to approx. 10 hours, the

signal lamp blinks permanently one time. No signal

tone sounds.

When recurrence of the transmission signal, the alarm

automatically ceases.

The manufacturer hereby declares that this device

conforms with the basic and other relevant requi-

rements laid down by directive RED (2014/53/EU).

The declaration of conformity can be downloaded

from „www.funk868MHz.de“.

This thermostat can be used in all EU and EFTA

countries.

5.5.3 Long time losses of the

transmission signal

If the receiver has not received an actuating signal for

more than 10 hours, the signal lamp shows a permanent

short ash. The signal tone sounds.

When the transmission signal recurs, the alarm auto-

matically ceases to sound.

For all types of faults, the following applies:

• The output is switched with 30 % (3 min. ON, 7 min.

OFF), this means heating with 30 % of capacity.

Note:

• Under unfavourable local conditions it is possible

that the radio link between the transmitter and the

receiver is insucient, for instance, if the receiver is

arranged in an interference-proof metal housing.

Please check whether the situation improves when

the transmitter is arranged in a dierent position.

For checking the radio link, see section 3.1.3

5.6 Troubleshooting

1. Valve does not open:

➩ Has it been properly wired up?

➩ Has the radio link been established

(see section 5.1)

➩ See point 3 in the Table 1 as well as point 3

onwards

➩ Press the Reset button (see 5.3)!

2. Signal lamp ashes and possibly a beeper

is sounding
