FlexCore Multi Heat Exchangers
Some FlexCore Series boilers contain multiple heat
exchangers. With this release, models after CK-3000 contain
more than one heat exchanger. These units rely on multiple
HeatNet controls that communicate between each other. In
order to do this, the Minibus was created. The Minibus uses
high speed serial SATA cables, a special interface, and is
located where the HeatNet Online module was.
Each heat exchanger’s control is currently connected by
ribbon cables to the display connectors at the bottom of the
display. Future releases will just use the minibus to transfer
settings rather than switching between the ribbon cables. So if
the Rear button is selected, the input ribbon cable is selected
and data from that control is accessed. Once
the appropriate
heat
exchange has been selected the Minibus Role can be set
or checked.
HeatNet controls attached to each heat exchanger are
designated either as a Manager, or a Subordinate. When
setting up a multi-heat exchanger FlexCore, the front
exchanger’s control is always designated as the Manager of
the boiler and the minibus. The other controls in the boiler are
set as subordinates and given a unique address. These roles
and addresses can be changed in the Settings – Distributed
Control menu.
To access the heat exchanger menus, select the boiler icon
button outlined below on the main screen. That will take you
to the Boiler Information screen.
From the Boiler Information screen, select the heat exchanger
button to be set up. It is in the top right corner of the screen.
Then select the settings button.
