<strong>Installation</strong> <strong>Guide</strong> <strong>ECL</strong> <strong>Comfort</strong> <strong>210</strong> / <strong>310</strong>, application <strong>A217</strong> / <strong>A317</strong><br />
Char. P post-run - <strong>A217</strong>.2 / <strong>A317</strong>.2 11042<br />
Circuit Setting range Factory setting<br />
1 0 ... 30 m 1 m<br />
Set the DHW charging pump (P2) post-run time (minutes). The DHW<br />
charging pump can continue to be switched ON after the DHW heating<br />
procedure in order to utilize the remaining heat in the heat exchanger.<br />
0 ... 30: Set the number of minutes for the post-run.<br />
Send desired T 11500<br />
Circuit Setting range Factory setting<br />
1 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 />
Circ. P frost T 11076<br />
Circuit Setting range Factory setting<br />
1 OFF / –10 ... 20 °C 2 °C<br />
Set the outdoor temperature value at which the DHW circulation pump is to<br />
be active to protect the DHW circuit against frost.<br />
OFF: The DHW circulation pump is not active.<br />
–10 ... 20: The DHW circulation pump is active when the outdoor<br />
temperature is lower than the set value.<br />
Frost pr. T (frost protection temperature) 11093<br />
Circuit Setting range Factory setting<br />
1 5 ... 40 °C 10 °C<br />
Set the desired flow temperature (S3) to protect the system against frost.<br />
5 ... 40: Desired frost protection temperature.<br />
P exercise (pump exercise) - <strong>A217</strong>.3 11022<br />
Circuit Setting range Factory setting<br />
1 OFF / ON ON<br />
Exercises the pump to avoid blocking in periods without DHW heating<br />
demand.<br />
OFF: The pump exercise is not active.<br />
ON: The pump is switched ON for 1 minute every third day at<br />
noon (12:14 hours).<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 />
