ECA addr. (choice of Remote Control Unit)
Circuit
1
Decides the communication with the Remote Control Unit.
OFF: No Remote Control Unit. Only room temperature sensor,
if any.
A:
Remote Control Unit ECA 30 / 31 with address A.
B:
Remote Control Unit ECA 30 / 31 with address B.
Demand offset
Circuit
1
The desired flow temperature in heating circuit 1 can be influenced by the
demand for a desired flow temperature from another controller (slave) or
another circuit.
OFF: The desired flow temperature in circuit 1 is not
influenced by the demand of any other controller (slave
or circuit 2).
1 ... 20: The desired flow temperature is increased by the set
value in 'Demand offset' , if the demand of the slave /
circuit 2 is higher.
P demand
Circuit
1
Choose conditions for the circulation pump in the heating circuit.
OFF: The circulation pump is ON when the desired flow
temperature in the heating circuit is higher than the
value set in 'P heat T'.
ON: The circulation pump is ON when the desired flow
temperature from slaves is higher than the value set in
'P heat T'.
Send desired T
Circuit
1
When the controller acts as a slave controller in a master / slave system,
information about the desired flow temperature can be sent to the master
controller via the ECL 485 bus.
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.

The Remote Control Unit has no influence on the DHW control.
The Remote Control Unit must be set accordingly (A or B).
Temp.
The function of 'Demand offset' can compensate for heat losses
between master and slave controlled systems.
The circulation pump is always controlled according to frost protection
conditions.
In the master controller, 'Demand offset' must be set to a value in order
to react on a desired flow temperature from a slave controller.
When the controller acts as a slave, its address must be 1, 2, 3 ... 9 in
order to send the desired temperature to the master (see the section
'Miscellaneous' , 'Several controllers in the same system').
