CTC EcoZenith i555 Pro 

CTC EcoZenith i555 Pro is a multi-tank with almost 
unlimited possibilities

The EcoZenith is intended for houses and properties with water-borne heat. 

The multi-tank features include intelligent control, a water volume of 540 

litres, bivalent mixing valve, two DHW coils, a solar coil and two 9 kW electric 

heaters giving a total of 18 kW. You can easily add another electric heater as 

an accessory to provide total power of 27 kW, controlled by the EcoZenith.

The control is specially adapted to simultaneously control up to three of 

CTC’s heat pumps, but it will also control and optimise the following:

•   Pool

•   

Energy storage in buffer tanks

•   

Three heating circuits simultaneously

•   

Solar panels and borehole recharging

•   

Cooling (passive cooling), floor or fan convector

•   

DHW circulation with time control

•   

Charging of extra DHW tank

•   

Connected wood boiler, gas/oil boiler and pellets

The CTC EcoZenith is well-insulated with 90 mm PUR and is well provided 

with connection options on both sides, ensuring clean and easy pipe 

installations. It also provides for extensions and additions to the system in 

the future.

The CTC EcoZenith i555 Pro is divided into two tanks which are isolated 

from each other in order to be able to hold different temperatures in the two 

tanks. This provides optimal function and operating economy.

The upper and the lower tanks are connected by heat distribution pipes 

which are especially developed for the solar energy to be able to form layers 

optimally in the entire volume of the tank and act as flow-through of the tank 

for wood operation, for instance (see picture).

Also refer to the "Electric heaters" 

section

 in the "Detailed Menu 

Descriptions" chapter (Installer/Settings/Electric Heaters).

section
