` Configuration of the base station with
room control unit Radio Display
CAUTION
Damage to the overall system
¾ Faulty configuration leads to errors and installati-
on damage.
The Service level of the base station Radio Display is
protected with a PIN code and may only be used by
authorized specialists.
¾ Press the rotary control.
¾ Select the menu "Service Level" and activate by
pressing.
¾ Enter the 4-digit PIN (standard: 1234) by rotating
and pressing.
¾ Select parameters (PAr) by pressing again and en-
ter the number code of the desired parameter (see
following table).
¾ Change parameters as required and confirm by
pressing.

` Configuration of the base station with the
microSD card
WARNING
Danger to life due to the electrical voltage
at the base station
¾ Only authorised specialists may perform the sys-
tem configuration via microSD card.
¾ Always disconnect from the mains network and
secure against unintended activation before
opening the base station.
The configuration of the base station is done via the
Service level of the room control unit Radio Display.
If no room control unit Radio Display is available,
configuration can alternatively be performed with a
microSD card. Only authorised specialists may per-
form this type of configuration.
Individual settings can be made via the EZR Manager
SD Card under www.ezr-home.de and transferred to
the base station via the microSD card. The base sta-
tion can read microSD cards with the formats FAT16
and FAT32.
CAUTION
Damage of the base station caused by im-
proper handling
¾ Never separate the base station from the mains
during the boot process
¾ Never remove the SD card from the unit before
the end of the boot process.
¾ Open www.ezr-home.de via the web browser of
a PC, select the menu item EZR Manager SD Card
and follow the instructions.
¾ Separate the base station from the mains voltage
and open it, see also "Installation".
¾ Insert the MicroSD card with the updated data
into the base station.
¾ Close the base station and apply mains voltage.
9 The base station restarts and the update process
starts automatically.
` Valve protection function
During periods without valve activation (e. g. outside
the heating period) the heating zone with logged-in
room control unit is activated in a cyclic way in order
to avoid a clogging of the valve.
` Antifreeze protection
Independent from the operating mode, the swit-
ching output is equipped with an antifreeze function.
As soon as a previously set antifreeze temperature
(5...10°C) is fallen short of, the valve of the allocated
heating zone is activated until this temperature is re-
ached. The antifreeze temperature can be set via the
service level of the RBG display or via the microSD
card (parameter 161).
` Emergency operation
If the base station is unable to establish a radio
connection to the room control unit after a set time
has elapsed, emergency operation is activated auto-
matically. In emergency operation, the switching out-
puts at the base station are activated with a modified
PWM cycle duration (parameter 181) independent
from the heating system in order to avoid complete
cooling of the rooms (in heating operation) or dewing
(in cooling operation).
` Resetting the factory settings
WARNING
Danger to life due to the electrical voltage
at the base station
¾ Only authorised specialists may open the base sta-
tion.
¾ Always disconnect from the mains network and
secure against unintended activation before
opening the base station.
¾ If present, remove the MicroSD Card from the
base station and delete the parameter file "pa-
rams_usr.bin" at the PC.
¾ Press the rmBUS key of the base station for three
seconds in order to start the pairing mode.
9 The LED "rmBUS" flashes.
¾ Press the rmBUS push-button again for a duration
of 10 seconds.
9 A restart will be performed.
9 Now the base station is reset to factory settings
and behaves as it did during the first commissi-
oning.
Note:
• All user settings will be lost.
• A previously allocated room control unit must
be paired newly.

` Cleaning

ning.
` Decommissioning
WARNING
Danger to life due to the electrical voltage
at the base station
¾ Always disconnect from the mains network and
secure against unintended activation before
opening it.
¾ Disconnect external voltages and secure against
unintended activation.
¾ Pull the mains plug and and disconnect the entire
installation.
¾ Remove the wiring to all externally connected
components as e. g. CO input/output and actu-
ator.
¾ Uninstall the device and dispose of properly.
` Disposal
The base station must not be disposed with
domestic waste. The operator has the duty
to hand the device to appropriate collection
points. The separate collection and orderly
disposal of all materials will help to conserve
natural resources and ensure a recycling in a
manner that protects human health and the
environment. If you need information about
collection points for your devices, please cont-
act your local municipality or your local waste
disposal services.
