Nothing gets lost
Your exchanges stay, grouped by date. Pick up the conversation from three weeks ago, rename it, delete it.
The right value, or nothing at all.
Hey JP answers with the exact passage from the manual — make, model, page. And when he does not have it, he tells you, instead of inventing a figure you would carry down to the boiler room.
Vaillant ecoTEC plus showing F.28, what’s the check procedure?
F.28 is a failed ignition at start-up. Check, in order: gas cock open, gas inlet pressure, then the ignition electrode and its lead.
Open the source and read the passage yourself before you touch the gas valve.
What this drew onSource 01Vaillant ecoTEC plus, installation and maintenance instructions, fault codes
Vitodens 200-W showing E10, what’s the check procedure?
I do not have any information on code E10 for the Vitodens 200-W in my documentation.
I will not guess a procedure on a gas appliance: the fault code list is in Viessmann's service instructions.

Your own manuals, in his answers.
Manufacturer documentation does not cover everything. Your internal procedures, your job sheets, the manual for a machine only you service: drop them in, and Hey JP answers from them.
Drop the manual in
PDF, Word or image, 25 MB per file, several at once. You fill in the make, the model and the year, and you choose whether the document stays with your company or goes to the community.
The document waits, its fields filled in, before you send it. It joins the base
Processing starts on its own. Every document shows its state — pending, processing, ready — with its make, its model, its size and who added it.
“1 document added. Processing starts.” Ask your question
Hey JP answers from your document and shows which one. You open the source to read the exact passage, and you decide.
The answer, and beneath it the document that produced it.

The ƒ(x) button in the composer opens a calculator, and its result goes into the exchange — assumptions and warnings included.

Narrow from the make, to the discipline, to the model printed on the casing, to the exact unit in front of you — and see every document and fault code Hey JP holds on it.
In the workshop.
What is being built right now, and what each one will change in your day.
