Hermann Micra 2 / Supermaster Thermomanometer Ref. H047006226
Pressure gauge for the boiler's water circuit. The dial shows a scale from 1 to 4 bar; the body has a small label with text that is illegible in the photos, so the manufacturer and code are not specified. It is replaced when it stops indicating pressure correctly or leaks from the fitting.

How to check if ref. H047006226 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Locate the reference printed on the body of the pressure gauge you have installed: it should indicate H047006226.
- Check your boiler model on the nameplate and look for it in the list of compatible models on this page.
- Compare the connections and the body with the original part before installing.
- If you have any doubts, send us a photo of the screen printing via WhatsApp and we'll confirm it for you before you purchase.
Symptoms and faults resolved by pressure gauge H047006226
The pressure gauge shows the pressure of the boiler circuit. These are the typical symptoms and what to do:
The pressure gauge stays at zero and doesn't respond no matter how much you fill the circuit.
Cause: The measurement mechanism is faulty and does not register the pressure even though the water enters normally.
Check with the filling key that water is indeed entering (you can notice the flow) before assuming the pressure gauge is broken.
The needle is stuck at a value and doesn't change no matter what I do with the filling valve.
Cause: The gear that moves the needle has seized internally and does not reflect the actual pressure changes.
Bleed a nearby radiator while monitoring the pressure gauge; if the pressure should drop and the needle doesn't move, it's the part.
Water is leaking right at the fitting where the pressure gauge connects to the boiler.
Cause: The sealing gasket of the connection has degraded over the years due to the pressure and temperature of the circuit.
Dry the area, tighten the fitting carefully, and observe for a few minutes; if it starts leaking again, the leak is from the pressure gauge.
The dial is not clear, it's fogged up or dirty, and it's difficult to read the pressure.
Cause: Moisture has gotten inside the glass or the dial has become dirty over time, without the mechanism necessarily being broken.
Clean the glass on the outside and check if the needle moves normally when bleeding; if the problem is only visual, assess it before replacing the part.
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
