4 Start-up and shut-down
4.1

Initialization and configuration

During initialization the ICM module (master) detects all
connected boilers and components and memorizes the
configuration.
The ICM module is configured automatically:
• during the first start-up of a ICM module,
• during a restart following a reset of the configuration
( chapter 4.3).
Configuration takes at least 5 minutes. During
G
configuration, the LEDS
connected boilers and possibly the LED to indicate BUS
J
communication ( table 9) flashes. Configuration is
completed and saved to the ICM when LEDS stops
flashing.
Any configuration saved remains in the memory, even in
case of power failure.
If, after configuration, a boiler (or an ICM module) is
temporarily shut down during active operation (e.g. for
G
maintenance), the LED
J
LED to indicate BUS communication begins to flash.
Following a restart, the boiler (or the ICM module) will
be recognized, and the associated LED stops flashing.
NOTE:
B Troubleshooting in case of faults
becomes more difficult if the saved
configuration does not match the actual
configuration of the heating system.
B Execute a reset after any intended/
remaining modification of the system
configuration (
new system configuration in the ICM
module (master).

Commissioning

NOTE:
B The cascade configuration is set during
start-up and after a reset
( chapter 4.1).

B Unplug the power connector from the first ICM
module.
B Power up all components of the heating system,
except for the ICM modules.
B Start all boilers (switch ON).
B Power up the first ICM by plugging the power
connector into its receptacle. If appropriate, the
configuration will then begin. This will take at least 5
minutes.
B Make the necessary adjustments on the individual
BUS subscribers in accordance with their installation
instructions.

Configuration reset

NOTE:
B The heating system configuration is saved
in the ICM master. Resetting the ICM
master deletes the entire configuration
(including that of the other ICM
modules).
Resetting the configuration deletes the system
configuration stored in the ICM module. During the next
start, the current system configuration is saved to the
ICM module.
B Unplug the power connector from the first ICM
module.
B Open the ICM module cover (master) (
page 11).
B Remove jumper ( fig. 4, page 9).
B Verify the correct connection of all heating system
components.
B Power up all components of the heating system,
except for the ICM modules.
B Start all boilers (switch ON).
B Power up the first ICM by plugging the power
connector into its receptacle.
CAUTION: Malfunction!
B When using system version 2 or 3, ensure
the correct position when reinstalling the
jumper.
B Reinstall the jumper (
