5.6 Application<br />
ECA addr. (choice of Remote Control Unit) 11010<br />
Circuit Setting range Factory setting<br />
1 OFF / A / B OFF<br />
Decides the communication with the Remote Control Unit.<br />
OFF: No Remote Control Unit. Only room temperature sensor,<br />
if any.<br />
A: Remote Control Unit ECA 30 / 31 with address A.<br />
B: Remote Control Unit ECA 30 / 31 with address B.<br />
Demand offset 11017<br />
Circuit Setting range Factory setting<br />
1 OFF / 1 ... 20 K OFF<br />
The desired flow temperature in heating circuit 1 can be influenced by the<br />
demand for a desired flow temperature from another controller (slave) or<br />
another circuit.<br />
OFF: The desired flow temperature in circuit 1 is not<br />
influenced by the demand of any other controller (slave<br />
or circuit 2).<br />
1 ... 20: The desired flow temperature is increased by the set<br />
value in ‘Demand offset’, if the demand of the slave /<br />
circuit 2 is higher.<br />
P demand 11050<br />
Circuit Setting range Factory setting<br />
1 OFF / ON OFF<br />
Choose conditions for the circulation pump in the heating circuit.<br />
OFF: The circulation pump is ON when the desired flow<br />
temperature in the heating circuit is higher than the<br />
value set in 'P heat T'.<br />
ON: The circulation pump is ON when the desired flow<br />
temperature from slaves is higher than the value set in<br />
'P heat T'.<br />
Send desired T 11500<br />
Circuit Setting range Factory setting<br />
1 OFF / ON OFF<br />
When the controller acts as a slave controller in a master / slave system,<br />
information about the desired flow temperature can be sent to the master<br />
controller via the <strong>ECL</strong> 485 bus.<br />
OFF: Information about the desired flow temperature is not<br />
sent to the master controller.<br />
ON: Information about the desired flow temperature is sent<br />
to the master controller.<br />
The Remote Control Unit has no influence on the DHW control.<br />
The Remote Control Unit must be set accordingly (A or B).<br />
Temp. Setting in<br />
‘Demand offset’<br />

Time<br />
The function of ‘Demand offset’ can compensate for heat losses<br />
between master and slave controlled systems.<br />
The circulation pump is always controlled according to frost protection<br />
conditions.<br />
In the master controller, 'Demand offset' must be set to a value in order<br />
to react on a desired flow temperature from a slave controller.<br />
When the controller acts as a slave, its address must be 1, 2, 3 ... 9 in<br />
order to send the desired temperature to the master (see the section<br />
‘Miscellaneous’, ‘Several controllers in the same system’).<br />
