This indoor module is suitable for both larger houses with high hot water demand, or the small rental house. It can control all components of one or more heating systems: solar and pool heating, additional hot water and buffer tanks, electric, wood, oil, gas and pellet boilers. It can even control several different types of heat pumps and choose which one to operate for the best economy. With built-in intelligent control, everyday life becomes easier.

CTC EcoZenith i555 Pro, the brain of your heating system, automatically detects which components are connected.

CTC EcoZenith i555 Pro has a touch display with a very user-friendly interface through which you can easily access all functions – just like your smartphone. You can also mirror the display on your tablet, phone or computer. But most importantly, it has a multi-language interface and clear symbols that make it easy to adjust heating, hot water, etc. and retrieve a wealth of information about the operation.

The CTC EcoZenith i555 Pro can control all components in one or more heating circuits: solar, pool heating, additional hot water tanks and buffer tanks, as well as electrical, wood, oil, gas and pellet boilers. It is also able to control many different types of heat pumps and select which is to be used for optimal savings.

The CTC EcoZenith i555 Pro has several connection points on the sides. This provides discreet and simple pipe installations along with possibilities to easily extend the system in the future.
