Installation Guide
An anti-bacteria function is available for activation on selected
days of the week.
If the desired DHW temperature cannot be reached, the heating
circuit can be closed gradually to allow more energy to the DHW
circuit.
A266.2, in general:
Alarm A1 (= relay 4) can be activated:
• if the actual flow temperature differs from the desired flow
temperature
• if the temperature at S3 exceeds an alarm value
Holiday programs are present for Heating and DHW. Besides, a
holiday program is present for the entire controller.
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 A266.2 has been uploaded, the ECL Comfort
controller starts in manual mode. This can be used for checking the
controlled components for correct functionality.
