A266.9, in general:
Alarm A1 (= relay 4) can be activated:
• if the temperature at S3 exceeds an alarm value
• if the pressure at S7 is not inside an acceptable pressure range
• if the alarm input S8 is activated
If the temperature at S3 exceeds the alarm value 'Max. flow T', the
circulation pump P2 is switched OFF after elapse of the 'Delay'.
P2 is switched ON again when the temperature at S3 gets below
alarm value.
When the subtype A266.9 has been uploaded, the ECL Comfort
controller starts in scheduled mode.
