Energy Efficiency Index - EEI
The benchmark for the most efficient circulators is EEI ≤ 0,20.
- Check that the circulator turns freely.
- Check that any antifreeze added does
not exceed the maximum percentage
of 30%.
- Switch off system power.
- Wait for the warning lights on the control
panel to go off, then power the system
again.
- Check that the mains voltage is correct,
if necessary reset it at the plate values.
- Check that the twin communication ca-
