Situation 3:
SLAVE controller: How to make use of the outdoor temperature
signal and send information about the desired flow
temperature back to the MASTER controller
The slave controller receives information about outdoor
temperature and date / time. The master controller receives
information about the desired flow temperature from slave
controllers with an address from 1 ... 9:
SLAVE controller:
•
In
, go to System > Communication > ECL 485 addr.
•
Change the factory set address from 15 to an address (1 ... 9).
Each slave must be configured with its own address.

Furthermore, each slave can send information about the desired
flow temperature (demand) in each circuit back to the master
controller.
SLAVE controller:
•
In the circuit in question, go to Settings > Application > Send
desired T
•
Choose ON or OFF.

ON or OFF
OFF:
Information about the desired flow temperature is not
sent to the master controller.
ON:
Information about the desired flow temperature is sent
to the master controller.
In the MASTER controller, the address in ‘ECL 485 addr. (master / slave
address)’, ID no. 2048, must always be 15.
