Pressure Gauge Boiler Wiesberg RSN/RSS - Unical Dua

The pressure gauge for the Wiesberg RSN/RSS boiler - Unical Dua is a device that measures and controls the pressure of the boiler circuit. If it fails, you will notice incorrect readings, which can cause the boiler to lock out due to a false lack of pressure or not regulate the temperature properly. This pressure gauge is compatible with several boiler models, including the Dua BTFS 24, Dua BTN 24, Dua CTFS 24, among others from the Unical range, as well as with the Wiesberg RSN 24, RSNE 24, RSS 24, and RSSE 24 models. A technician must confirm through diagnosis whether it is necessary to replace it when it shows faults in the readings or malfunctions.

Guide

How to check if it is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference —. If it is not visible, do not identify the part by its shape alone.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Diagnosis and fault codes

Symptoms that require diagnosis on the manometer

The manometer shows the pressure of the boiler circuit. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The needle does not move, regardless of the circuit pressure.

    Cause: The internal mechanism does not respond to changes in water pressure.

    Bleed a radiator to lower the pressure and see if the needle moves even a little.

  • 02

    The pressure cannot be read from the front of the boiler.

    Cause: If the dial is dirty, scratched, or fogged, the reading is not reliable even if the circuit is functioning properly.

    Clean the dial and check if the problem was just visibility before assuming that the pressure gauge is broken.

  • 03

    The needle remains fixed at the same value, whether bleeding or filling.

    Cause: The mechanism that moves the needle has seized up and does not follow the actual water pressure.

    Fill the circuit for a few seconds with the filling key and observe if the needle moves away from the fixed value.

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.
