4 Start-up and shut-down
4.1 Configuration
With this configuration, the control characteristics of the
MCM10 module (master) are adapted to the specific
heating system.
The MCM10 module is configured automatically:
• during the first start-up of a MCM10 module,
• during a restart following a reset of the configuration
(Æ paragrahp 4.3).
Configuration takes at least five minutes. During
configuration, the LEDs associated with the connected
heating appliances and possibly the LED to indicate BUS
communication (Æ Tab. 9) flash. Configuration is
completed and saved to the MCM10 when LEDs stop
flashing.
Any configuration saved remains in the memory, even in
case of power failure.
If, after configuration, a heating appliance (or a MCM10
module) is temporarily shut down during active operation
(e.g. for maintenance), the LED allocated to that
heating appliance or the LED to indicate BUS
communication begins to flash. Following a restart, the
heating appliance (or the MCM10 module) will be
recognized, and the associated LED stops flashing.
4.2 Commissioning
B Ensure the correct connection of all heating system
components.
B Provide the power supply (120 V AC) for all
components of the heating system, except for the
MCM10 modules.
B Start all heating appliances (switch ON).
B Provide the power supply via the power plug of the
(first) MCM10 module. 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.
4.3 Configuration reset
Resetting the configuration deletes the system
configuration stored in the MCM10 module. During the
next start, the current system configuration is saved to the
MCM10 module.
B Interrupt the power supply to all MCM10 modules.
B Open the MCM10 module cover (master) (Æ Fig. 6,
page 10).
B Remove jumper (Æ Fig. 3, page 9).
B Ensure the correct connection of all heating system
components.
B Provide the power supply (120 V AC) for all
components of the heating system, except for the
MCM10 modules .
B Start all heating appliances (switch ON).
B Provide the power supply via the power plug of the
(first) MCM10 module.
B Reinstall the jumper (Æ Fig. 3, page 9).
Configuration starts. This will take at least 5 minutes.
B Close the MCM10 module cover (Æ Fig. 6, page 10).
4.4 Shutting down
To take the heating system out of use:
B Interrupt the power supply to all MCM10 modules and
all heating appliances.
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 (Æ section 4.3) to save the
new system configuration in the MCM10
module (master).
The cascade configuration is set during start-
up and after a reset (Æ paragrahp 4.1).
B Monitor the LEDs during configuration to
detect cable breaks or wiring faults.
The heating system configuration is saved in
the MCM10 master. Resetting the MCM10
master deletes the entire configuration
(including from the other MCM10 modules).
CAUTION: Malfunction!
B When using system version 2 or 3, ensure
the correct position when reinstalling the
jumper.
WARNING: System damage due to frost.
B Ensure frost protection if the heating
system is to remain out of use for longer
periods (Æ heating appliance installation
instructions).
