CTC EcoZenith
I
550
Current Monitor
The CTC EcoZenith
I
550 has a built-in current monitor. If the system is installed with
current sensors (included), there is a constant monitoring to prevent overload of the main
fuses of the house. If this should happen, electric stages are disconnected from the CTC
EcoZenith
I
550. At increased heat requirements and in combination with single-phased
motor heater, stove, washing machine or dryer, e.g., the product’s immersion heaters
could be limited. This can lead to that neither the heating temperature nor the domestic
hot water temperature is sufficient.
If the CTC EcoZenith
I
550 is restricted, this is shown in plain text on the display. Ask the
electrician if the fuse size in the house is correct.
Sound Problems
Sudden pressure changes in the tap water system may cause noise. This is due to pressure
surges which occur when, for instance, an older type of instant closing mixer is turned
off quickly. The fault is not in the CTC EcoZenith I 550, and the problem can be easily
rectified by replacing the mixer with a soft-closing one. In the case of noise from hard
closing dishwashers and washing machines, this can be rectified with a pressure surge
damper, which is also a viable alternative to soft closing taps/mixers. Minimizing pressure
surge benefits the whole of the tap water system in general!
If gushing sounds can be heard from the product, check that it is well purged. Turn the
safety valve for the boiler so that any air is evacuated. If necessary, fill up with more water
so that correct pressure is obtained. If the problem is repeated, have a specialist check
the cause.
