code

In communications and information processing, code is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form, sometimes shortened or secret, for communication through a communication channel or storage in a storage medium. An early example is an invention of language, which enabled a person, through speech, to communicate what they thought, saw, heard, or felt to others. But speech limits the range of communication to the distance a voice can carry and limits the audience to those present when the speech is uttered. The invention of writing, which converted spoken language into visual symbols, extended the range of communication across space and time.
The process of encoding converts information from a source into symbols for communication or storage. Decoding is the reverse process, converting code symbols back into a form that the recipient understands, such as English or/and Spanish.
One reason for coding is to enable communication in places where ordinary plain language, spoken or written, is difficult or impossible. For example, semaphore, where the configuration of flags held by a signaler or the arms of a semaphore tower encodes parts of the message, typically individual letters, and numbers. Another person standing a great distance away can interpret the flags and reproduce the words sent.

    WB Greenstar 4000 Combi Fault Code 2965

    What is the boiler flow temperature required to flag this 2965 fault code?. This, I believe, is a blocking code that trips the burner but when/if it resets. the burner will refire without any boiler reset? If this fault code is up while in CH mode and there is a demand for HW, will the boiler...

    Ideal boiler had the F1 code, so topped pressure up but code persists.

    After researching as much as I can to sort this problem, I keep reading that if your Ideal boiler has an F1 code and the pressure is low, it needs topping up. If it has an F1 code but the pressure is fine, then this indicates a potential pressure sensor fault. What if it was low (completely...
