6.8 Alarm

Many applications in the ECL Comfort 210 and 310 series have an
alarm function. The alarm function typically activates relay 4 (ECL
Comfort 210) or relay 6 (ECL Comfort 310).
The alarm relay can activate a lamp, a horn, an input to an alarm
transmitting device etc. etc.
The relay in question is activated as long as the alarm condition
is present.
Typical alarms:
• Actual flow temperature differs from the desired flow
temperature.
• An activated circulation pump does not generate a pressure
difference.
• The refill water function does not generate a pressure within
a preset time.
• A universal alarm input (application dependent) is activated.
