Hello, Error 04 is displayed on the Ecocondens boiler. I have a single-function boiler. According to the instructions, it is a pressure problem and the central heating system needs to be refilled (there is no water). In the case of single-function boilers, water is topped up in the installation...

Above the hopper. Two valves (connected with a flexible hose), one you turn fully, the other slowly slightly. You will hear hissing You look for a pressure of 1.2 bar on the manometer. You turn off these two valves. You write it down and tell other household members how to get water into the central heating system.

I did this, the error actually disappeared, the stove seems to be working, the bathroom radiators are warm, but the temperature does not change on the Salus controllers and I actually feel that the house is not warmer. Should I wait or do something else? Did it matter which of these valves I opened completely and which only a little? Added after 8 [minutes]: I also changed the temperature on the floor stove from 37 to 45, but it didn't help

The thing about underfloor heating is that it takes a long time to heat up and releases heat for a long time. It`s better to keep the temperature low all the time rather than suddenly.

Thanks for the advice, problem solved

Hello,
Error 04 is displayed on the Ecocondens boiler. I have a single-function boiler. According to the instructions, it is a pressure problem and the central heating system needs to be refilled (there is no water). In the case of single-function boilers, water is topped up in the installation using a filling valve located on the central heating system. The question is which valve is it? I am attaching 2 photos.
