<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 />
6.9 Alarm<br />
Alarm for monitoring the flow temperature is only available in<br />
circuit 2 in <strong>A275</strong>.3 and <strong>A375</strong>.3 applications.<br />
Many applications in the <strong>ECL</strong> <strong>Comfort</strong> <strong>210</strong> and <strong>310</strong> series have an<br />
alarm function. The alarm function typically activates relay 4 (<strong>ECL</strong><br />
<strong>Comfort</strong> <strong>210</strong>) or relay 6 (<strong>ECL</strong> <strong>Comfort</strong> <strong>310</strong>).<br />
The alarm relay can activate a lamp, a horn, an input to an alarm<br />
transmitting device etc.<br />
The relay in question is activated as long as the alarm condition<br />
is present.<br />
Typical alarms:<br />
• Actual flow temperature differs from the desired flow<br />
temperature.<br />
6.9.1 Temp. monitor.<br />
Upper difference 12147<br />
Circuit Setting range Factory setting<br />
2 OFF / 1 ... 30 K OFF<br />
The alarm is activated if the actual flow temperature increases more than<br />
the set difference (acceptable temperature difference above the desired<br />
flow temperature). See also 'Delay'.<br />
OFF: The alarm function is not active.<br />
1 ... 30 K: The alarm function is active if the actual temperature<br />
gets above the acceptable difference.<br />
Lower difference 12148<br />
Circuit Setting range Factory setting<br />
2 OFF / 1 ... 30 K OFF<br />
The alarm is activated if the actual flow temperature decreases more than<br />
the set difference (acceptable temperature difference below the desired<br />
flow temperature). See also 'Delay'.<br />
OFF: The alarm function is not active.<br />
1 ... 30 K: The alarm function is active if the actual temperature<br />
gets below the acceptable difference.<br />
