Cewal Thermometer for Saunier Duval Thelia Twin 28 E Boiler
Sphere and bulb thermometer with a scale of 0-120°C, manufactured by Cewal (Camponogara, Italy), screen printed on the piece itself. It is installed in Saunier Duval boilers from the Thelia Twin, Themis Twin, Sylva, Isotwin, and Twin C/F ranges. The boiler manufacturer is not the manufacturer of the component. It is replaced when the thermometer does not indicate temperature or the bulb loses tightness.

How to check if the ref. 05601000 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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 05601000. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the pressure gauge 05601000 solves.
The manometer shows the pressure of the boiler circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The thermometer does not register a temperature or the needle is completely stuck.
Cause: The remote bulb loses tightness or the mechanism gets stuck, preventing the needle from responding to the heat of the circuit.
Check that the bulb is properly inserted into its measuring sleeve and has not come out before replacing the part.
- 02
The dial is cracked or the temperature scale is not clearly visible.
Cause: The glass of the gauge cracks due to impacts or continuous vibration from the boiler in operation.
Check if the internal mechanism is still functioning despite the crack: does the temperature of the boiler rise or fall, and observe if the needle follows the change before discarding the entire part.
- 03
There is a leak or moisture in the area of the temperature bulb.
Cause: The bulb, which is a sealed reservoir, can lose its tightness over time or due to corrosion, causing it to start leaking.
Dry the area of the bulb and its sleeve, and check again in a few hours: if moisture reappears right there, the leak is from the bulb and not from another nearby connection.
- 04
The needle moves but indicates a temperature very different from what is felt in the circuit.
Cause: The bulb may have shifted from its contact point in the sleeve, or the mechanism has lost precision with use.
Check that the bulb reaches the bottom of its immersion sleeve, without being halfway, before considering the reading as incorrect.
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.
