6. Installation / start-up
Installation:
• Only in the electrical or heatingcircuit junction box on DIN (i.e.
“top-hat section”) rails
• Any installed attitude is possible.
• Water must not be allowed to reach the device.
Electrical connections:
Important: disconnect the device from the power supply before
making the electrical connections.
See circuit diagram in the device and Figs. 1 – 10.
For normally-open thermal actuators, see 4.8.
Connecting the operating voltage:
Insert the plug into the power socket. If a direct connection is
needed, remove the plug and connect the wires in the power ca-
ble directly.
On completion of installation work, a link must be established be-
tween the INSTAT 868-r ... transmitter and the appropriate chan-
nel (1...8) (see 4.1 onwards).
After switching on, the display shows the operating voltage and
the software version briefly.
6.1 External antenna
If reception conditions are difficult, a separate version of the de-
vice with provision for connecting an external antenna (ZA
193 772) is available.
Run this in via the cable ports on the casing and connect it to the
antenna socket.
6.2 What to do if …
1. Valve does not open:
-> see Table 1
-> perform a ‘reset’: see 4.15
2. A signal lamp for one radio channel is flashing (a beep
signal may also be heard)
-> Basic information: see 4.16
-> Learning mode, valve test, radio link test not interrupted
(see 4.15)!
-> Two transmitters are supplying signals with the same ad-
dress; one of the radio links must be re-learned
(see 4.7.1)!
-> No radio link; see Table 1
-> One or more channels flash to indicate that they have no
link with their transmitte
Restore the necessary links (see 4.1)
If necessary, carry out “Delete radio links” (see 4.3) and
create new links.
3. Channel 8 lights up although no transmitter has been
‘learned’
-> Channel 8 is used for pump logic (see 4.9).
If any unexplained faults develop, it is best to press the ‘Reset’
button on the thermostat and if necessary on the receiver.

This thermostat can be used in all EU and EFTA countries.
The manufacturer hereby declares that this device con-
forms with the basic and other relevant requirements laid
down by directive R&TTE 1999/5/EC.
The declaration of conformity can be downloaded from
„www.funk868MHz.de“.
Note: In isolated cases a secure and permanent link between
the transmitter and receiver may not be possible. The cause
is not to be sought in our radio control system but in the fre-
quency range being used. You are therefore recommended
to test the system for efficient operation at the place where
it is to be installed.
8. Brief manual
Radio functions Chapter Action
Establish the radio link, switch output 4.1 Set the transmitter to the learning mode
(see instructions supplied with transmitter)
At the receiver:
MODE until -> L (channels already ‘learned’ light up)
OK -> Lamp for room 1 flashes
+/- -> Select the channel to be ‘learned’
OK -> Channel flashes + seconds counted
When link is established -> lamp remains on steadily
Terminate the learning mode, start learning for next channel
if necessary
Radio link range test 4.2 Establish the radio link as described above
When transmitter has ‘learned’ and channel lamp remains on
Move the transmitter farther away
If the lamp flashes, the range has been exceeded.
MODE to end the procedure; terminate learning mode at
transmitter
Deleting radio link 4.3 MODE until -> dEL (channels already ‘learned’ light up)
OK -> dEL flashes
OK -> activates “Delete”
Determining active links 4.4 MODE until -> L (channels already ‘learned’ light up)
MODE to end the procedure
Audible alarm signal 4.6 Is only sounded between 10h and 20h

being sounded
Master / slave 4.5
Master = thermostat with timer; slave = thermostat without timer
Slaves at channels with a higher number than the master
comply with the master, (not with the timer in the receiver)
