Communication - Danfoss ECL Comfort 100M User's Manual And Installation Instructions

Communication

The ECL Comfort controller can be connected to
external units via the ECL Comfort BUS.
Master / slave systems
If the controller is part of a larger system with several
controllers, you can connect the controllers with each other
and send information to them using the same outdoor sensor.
The controller which is physically connected with the out door
sensor is the master of the entire system and gets the address
15. The other controllers in the system can be addressed with
a slave number and receive information from the outdoor
sensor through the master.
If a slave has an address higher than 0, a reference
temperature demand can be sent to the master. The master
sends an outdoor temperature signal to the slaves. When a
slave has the address 0, only the outdoor temperature signal
is transferrred from the master to the slave.
