1. Application
This unit from the INSTAT 868 family converts information from the
INSTAT 868 transmitters into control signals for the valves. Additional
functions allow the temperature to be altered for a preset period of
time.
2. Features
General:
• Ready to plug in to a 230 V power socket.
• Backlit display
• 24 V thermal actuators are directly connectable
(a separate version is available for 230 V thermal actuators)
• Heating/cooling changeover using an external signal 230 V
• Cooling shutdown at dew-point using an external signal (using
mains power signal or a directly connected dew-point sensor)
• Pump logic function via volt free relay (pump off is all valves are
closed)
• Heater control function via volt free relay output (Heater off if all
valve are closed))
• Valve testing function
• Valve/pump protection (prevents jamming)
• Programming is possible even with cover removed (only if the
device is disconnected from mains)
Timer
• 8-channel timer for up to 8 time zones
• Preset real-time timer, no setting required
• Automatic summer/winter time changeover
• 6 time profiles, all adjustable
• Holiday function (reduction for a maximum of 200 days)
Warning!
The unit must only be opened by a qualified electrician and should
be installed in accordance with the circuit diagram shown on the unit
and in compliance with these instructions. All valid health and safety
regulations must also be complied with.
This is an electronic device that is mounted in a switch cabinet to
control thermostats and valves. It is to be used only in dry rooms and
enclosed spaces where normal ambient conditions apply.
The device confirms to EN 60730, it works according operating
principle 1C.
Radio communication
• 8 reception channels in one casing
• Master/slave function (master timer thermostat specifies switching
times, not the integrated timer)
• One transmitter can control several reception channels
• Transmitter has an auto-learn address setting using learning mode
• A signal lamp for each output displays relay status, faults etc.
• Alarm sounds if a fault is detected
• Monitoring of valid addresses
• Transmitter monitoring (if nothing is received from the transmitter
for a long period, for instance if the battery is flat), the output is
switched on for 30% of the time and the signal lamp blinks.

4. Functional description
The INSTAT 868-a8U receiver converts the radio signals from the
INSTAT 868-r… transmitter into control signals for electrical
consumers such as thermal actuators. The consumers are switched by
relays, with signal lamp to display the switched status in each case.
For relay switching behaviour, see ‘Functional description’ in
transmitter installation instructions.
Room temperatures can be influenced by varying the time settings at
the built-in 8-channel timer.
4.1 Time and Date setting
Press key is displayed+until CLOC
Press:
OK year is displayed, digits are blinking
- /+ to change
OK Day, Month is displayed, Day is blinking
- /+ to change
OK Month is blinking
- /+ to change
OK day of week is blinking
- /+ to change
OK Time is blinking

4.2 Setting the holiday function
ß
The rooms can be reduced in temperature to the value selected at
their thermostats for a predetermined period (max. 200 days).
Press
+until HOL will be displayed
Press OK The number of days is blinking =
00:1d
The arrow is against the ßsymbol.
Press - /+ to change the figure.
Press OK to confirm the new setting.
If the holiday function is active, the arrow can be seen against the
ß
symbol. At midnight on the last day of the holiday period, automatic
operation is selected again and the preset program goes back into
operation. (If for example 1 day is selected as the holiday period, the
automatic function is restored at midnight on that day. To deactivate
the function, press ESC.
Master comply with their own holiday periods, not the one selected
here.
The function continues after a power failure.
Note: this function has no effect in the “Cooling” mode; the
temperature is not raised.
5. Installer Settings
These settings should only be modified from an expert. Wrong
adjustments could result in a damage of the heating system.
In order to protect from unwanted modifications a CODE protects
these menu items
In order to move to the CODE:
Press:
key
- /+ until CodE is blinking
OK press for ~ 5 sec to accept. This activation of the
code will be valid for 1h. In this case Code will not
displayed any more
In the descriptions below the necessary key presses will be described
in order to go to a specific function, this will be done in the form:
Press key
+until (CodE) ➜Funk (OK) ➜LErn is visible.
(OK) means press OK key
5.1 Radio link set-up
Up to eight transmitters control either one or several
‘Heating/cooling ON/OFF’ channels (1 … 8) (channel 7, 8 may be
illuminated, see 5.8, 5.9).
One or several thermal actuators can be connected to each output.
For an example, see Fig. 1, 2.
Only the INSTAT 868-r1 (without timer) follows the time profile
of this receiver in the automatic mode.
The radio link is set up in the following steps:
a) Select the ‘Learning mode’ at the transmitter for the desired room
(see transmitter operating instructions).
b) At the receiver, set the desired channel to the learning mode as
follows:
Press key
+until (CodE) ➜Funk (OK) ➜LErn is displayed
OK already learned channels will be displayed
channel LED 1 and R1 is blinking,
F0 L is displayed
- /+ to change channel until the lamp of required room
is blinking
OK to start learning mode
The channel LED and room arrow are blinking, digit
in front of
Lincrements in sec interval e.g. F1:9L
the actual received signal power will be displayed a
sound can be heard.
If link is established, blinking and sound stopps, the room
arrow remains, to show the latest learned channel
c) Stop the learning mode at the transmitter.
To ‘learn’ the next room, carry out step a) and select the
appropriate channel at the receiver, by using
- /+ key.
To allocate several reception channels to the same
transmitter, leave the transmitter in the learning mode and
‘learn’ the relevant channels one after the other.
ESC to cancel
Display of signal power
F3= good
F2 = medium
F1 = not enough
F0 = no signal
Notes:
• The function is interrupted automatically if no button is pressed for
10 minutes return to standard status➜
• Each channel needs about 30 seconds’ learning time.
• Learning at channel 7 cancels heater control.
• Learning at channel 8 cancels pump logic.
• One transmitter can control several reception channels
(several valves per transmitter).
5.2
Test radio distance / signal power / learned channels
Each channel provides info about the received signal power. This is
used to estimate the signal power/radio distance
Press key
+until (CodE) ➜Funk (OK) ➜dIST is displayed
a) Note: Not possible with removed cover
OK already learned channels will be displayed
channel LED 1 and R1 is blinking, the last signal
power will be displayed e.g.
F1:dI
- /+ to change channel
channel LED and room arrow is blinking, the last
signal power will be displayed
Signal power see 5.1
The power of the received signals will be displayed
(F1...F3).
F0 for no signal (e.g. between signal packages)
b) Move the transmitter away and turn the temperature set point
from min to max and vice versa. This allows estimating the distance
Alternative: INSTAT+ 868 Use function "Test radio distance"
INSTAT 868-r1 press Reset, the corresponding channel
will blink several times
5.3 Deleting radio links
To delete all radio links:
Press key is displayed+until (CodE) ➜Funk (OK) ➜dEL
OK
already learned channels will be displayed on the LEDs
dEL will is blinking
OK to delete all links
