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.

Circuit
Sub-circuit in the same ECL controller:
Information about the desired flow temperature can be sent to circuit 1.
The ECL 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 circuit 1 / master circuit / the master controller.
ON:
Information about the desired flow temperature is sent
to circuit 1 / master circuit / the master controller.

Temp.
The function of 'Demand offset' can compensate for heat losses
between master and slave controlled systems.
Slave circuits are circuits in other ECL controllers.
Sub-circuits are circuits besides the master or circuit 1 in the ECL
controller.
ON
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').
