<strong>Installation</strong> <strong>Guide</strong> <strong>ECL</strong> <strong>Comfort</strong> <strong>210</strong> / <strong>310</strong>, application <strong>A275</strong> / <strong>A375</strong><br />
7.2 Application<br />
Ch.-o. valve / P (changeover valve / pump) 13051<br />
Circuit Setting range Factory setting<br />
3 OFF / ON ON<br />
Choose whether the DHW heating control is based on a changeover valve<br />
or a pump.<br />
OFF: Changeover valve<br />
ON: Pump<br />
Tank, sec. / prim. 13053<br />
Circuit Setting range Factory setting<br />
3 OFF / ON OFF<br />
Choose whether the heating of the DHW tank is dependent on the flow<br />
temperature at S3.<br />
OFF: The DHW tank is heated by means of the S3 temperature.<br />
ON: The DHW tank is heated separately. The S3 temperature<br />
has no influence on the DHW heating.<br />
DHW P post-run 13041<br />
Circuit Setting range Factory setting<br />
3 0 ... 30 m 0 m<br />
Set the DHW pump (P3) post-run time (minutes). The DHW pump can<br />
continue to be switched ON after the DHW heating procedure in order to<br />
utilize the remaining heat in the heat exchanger / boiler.<br />
0 ... 30: Set the number of minutes for the post-run.<br />
Send desired T 13500<br />
Circuit Setting range Factory setting<br />
3 OFF / ON ON<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 />
Frost pr. T (frost protection temperature) 13093<br />
Circuit Setting range Factory setting<br />
3 5 ... 40 °C 10 °C<br />
Set the desired flow temperature to protect the DHW system against frost.<br />
5 ... 40: Desired frost protection temperature.<br />
When the changeover valve is chosen, pump P1 is ON at heating as<br />
well as at DHW heating demand.<br />
When the pump is chosen, pump P1 is ON at heating and OFF at DHW<br />
heating demand.<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 />
