Installation is to be carried out in the following
sequence:
• remove temperature adjustment knob
• loosen retaining screw
• remove housing top
Warning:
Discharge static charge of human body before
touching electronic equipment for repositio-
ning jumpers, e. g. by briefly touching heat or
water pipes.
5 Commissioning
Upon installation, a connection must be made between
controller (transmitter) and receiver. For application
examples, see receiver instructions.
To do so, proceed as follows:
1.
Activate "learning mode" on the receiver (see
there).
2.
Activate "learning mode" on the transmitter as
follows:
a) Press and hold ì button.
b) Briefly press reset button
c) When indicator lamp lights up, release ì button
When the connection has been successfully
made, the indicator lamp automatically extin-
guishes ( after approx. <1 min.).
d) Press the reset button on the transmitter. This will
terminate the "learning mode" and the indicator
lamp will extinguish.
Warning: Keep a distance of more than 2 m
between transmitter and receiver.
Note:
Activating learning mode will create a new address, all
revceivers linked to that transmitter need to be
re-learned.
Easy replacement of a receiver see 5.2.
The transmitter exits the learning mode after 10 min.
The temperature controller is now ready for
operation. When testing the radio transmis-
sion, please observe also the relevant receiver
instructions.
5.1 Performance testing
After pressing the reset button (caution, timer will be
cleared), the transmitter changes to testing mode for
15 sec. Depending on the position of the mode selector
switch, various different flashing signals will be transmit-
ted to the receiver.
The flashing starts with a pause.
ê Permanent comfort temperature
The receiver flashes 3 times for normal temperature
ë Permanent setback temperature
The receiver flashes depending on the setback temper-
ature set (see 3.7 Function of the jumpers)
2 times for a 2 K temperature setback
1 times for a 4 K temperature setback
è Automatic operation
The receiver flashes:
3 times for normal temperature
í
Off
The receiver does not flash.
Manual activation of receiver output
(not in OFF position):
Switching on:
Set a temperature of 30 °C, wait approx. 30 sec.
Switching off:
Set a temperature of 5 °C, wait approx. 30 sec.
5.2 Replacement of a receiver without
re-learning of transmitters
The method described here offers the benefit, that the
actually used address will be continued to be used.
Only the replaced receiver needs to be re-learned.
To do so, proceed as follows:
1. Activate "learning mode" on the receiver (see there).
2. Activate "learning mode" on the transmitter as
follows (below lid):
a) Hold ì button depressed for > 8 Sec.
b) When the indicator lamp lights up, release the button.
When the connection has been successfully made, the
indicator lamp automatically extinguishes (after <1 min.).
c) Press the reset button on the transmitter. This will
terminate the "learning mode" and the indicator
lamp will extinguish.

vironment and cut down the waste of precious
ressources. Your local waste management au-
thority will upply you with the details concerning the proper
disposal of batteries.
This product should not be disposed of with household waste.
Please recycle the products where facilities for electronic
waste exist. Check with your local authorities for recycling

This thermostat can be used in all EU and EFTA countries.
The manufacturer herewith declares that the device
complies with the basic requirements and all other relevant
regulations of the RED Directive 2014/53/EU. The declaration of
conformity can be downloaded from "www.imi-hydronic.com".
Note: In some rare cases it may not be possible to
establish a permanent radio link between the radion
transmitter and the radio receiver. We therefore
recomment to check the reliability of operation at the
specific location.
