The Junkers CW 400 system controller for gas or oil boilers and up to 4 heating circuits is very intuitive to use. It can be used with room temperature control or in connection with an optional outdoor sensor. Its clarity results from distinct, large shapes and a high quality finish which characterises the elegant, nicely rounded design. The combination of touch-keys and one button operation is particularly simple and is supported by a large display. An extensive diagnostic menu provides technical experts with monitoring values for the boiler, shows faults with a fault memory as well as offering functional tests. Customers have their own individually configurable programme menu. Plain text messages and graphics help the user to control the diverse functions. The CW 400 also supports an Internet connection. This means that by using the corresponding Junkers app, remote access can be set up for both customers and technical specialists.
