If the thermostat has never been
paired with the radio module
(factory setting), then pairing
occurs after pressing the
button, without having to enter the
user menu.
The correctness of the pairing will be
confirmed by the message "END" and
"Succ" on the thermostat. The and
symbols are also no longer visible on the
thermostat screen. During the active pairing
mode, you can pair, in the same way,
subsequent thermostats. After correctly
pairing the thermostats with the radio
module, end the pairing mode in the main
regulator menu or you can wait for the active
pairing time to expire.
After establishing the radio connection with
the thermostat in the main controller
Information menu, the thermostats will be
shown as eSTER_x40, with the version of the
software displayed.
Connecting the radio module to the
master controller again does not
require pairing if the thermostats
have previously been paired.
Pairing directly from the radio module:
With limited compatibility of the main
controller program with the radio module,
the P button of the radio module is used to
start the pairing mode, which should be
briefly pressed once - then the LED will start
to flash, which means that the pairing mode
will be activated for 4 minutes.
Only one thermostat should be paired at this
time, analogously as described during pairing
from the main controller menu level. After
correct pairing of the thermostat, end the
pairing mode by briefly pressing the P button
or wait until the active pairing time expires.
After establishing the radio connection with
the thermostat in the main controller
Information menu, the thermostat will be
visible as ecoSTER TOUCH, with the given
version of the software.
The pairing method with the P
button can also be used when the
radio module program is fully
compatible with the main controller.
15.3 Resetting the memory of the radio
module pairing
The radio module stores data on paired
thermostats in its memory, so after replacing
any thermostat it is necessary to reset the
memory of the radio module by setting the
parameter in the main controller menu:
MENU → General settings → Radio
module settings → Delete the device
association = Yes.
Memory reset can also be performed by
pressing the P button of the radio module for
about 8 seconds. Confirmation of removing
the pairing memory is to turn off the LED for
a moment, immediately after releasing the P
button.
The reset radio module requires re-
pairing with thermostats.
15.4 Cooperation of the radio module
with several thermostats
The cooperation of the main
controller with more than one
thermostat is possible only when
the radio module program is fully
compatible with the main controller.
To check if the main controller program is
fully compatible with the radio module, select
the tab in the main controller menu:
MENU → Information → Programs
versions and if ISM_xSMART information is
visible, with the displayed version of the
program, the radio module will work with up
to three thermostats, if there is no
information, the radio module can work with
only one thermostat. In order to check if it is
possible to get full cooperation with
subsequent thermostats, contact the
manufacturer of the main regulator, who will
determine if it will be possible to update the
