Refurbished Chaffoteaux Pressure gauges & aquastats

Chaffoteaux Celtic 2.16-2.24 RSc Aquastat Ref. 60100606-30

If you notice that the boiler does not regulate the temperature properly or gets blocked due to a false pressure drop, a technical diagnosis must confirm if you need a new pressure gauge, such as the Chaffoteaux Celtic 2.16-2.24 RSc aquastat. This part measures and controls the pressure or temperature of the circuit, ensuring proper operation. It is installed in boilers from the Celtic range, including models such as 2.16, 2.18, 2.20, 2.20 FF, 2.23, and 2.24 RSc, among others. A technician must confirm through diagnosis if it needs to be replaced when the readings are incorrect, as it can affect the performance of the boiler.

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.

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.
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.

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 boiler heats less than what you request or never turns off due to temperature.
Cause: The aquastat does not cut the signal when it should, due to the wear of the internal contact.
Measure the continuity of the aquastat with the multimeter in both cold and hot conditions to check if it changes state.
02
The boiler keeps stopping and starting constantly, in very short cycles.
Cause: The aquastat contact operates intermittently and does not stay fixed in its position.
Make sure that the bulb is properly seated in its sleeve, without any play or rust around it.
03
The boiler locks out due to overheating even though the water is not particularly hot.
Cause: The aquastat gives an incorrect reading because the bulb does not make good thermal contact with the water.
Clean the sleeve of the bulb from scale or dirt before replacing the part.
04
The boiler does not ignite at all, as if it is not receiving a prior command.
Cause: The aquastat contact remains permanently open and interrupts the ignition circuit.
Measure the continuity of the aquastat when disconnected to confirm if the contact is broken before purchasing a new one.

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.

Frequently Asked Questions

Frequently asked questions about the pressure gauge

What temperature is the aquastat of the Chaffoteaux Celtic 2.20 FF set to?

According to two independent external sources, at 57 °C, equivalent to the TC300001 model with a single bulb.

Do the photos on the datasheet for Ref. 60100606-30 correspond exactly to the part that is shipped?

No: the photos show a TC30002 label of a different part with a double bulb, and should not be taken as technical data for the unit being sold.

Is this aquastat suitable for the Celtic 2.16 or only for the 2.24 RSc?

It is suitable for both: Celtic 2.16, 2.18, 2.20, 2.20 FF, 2.23, 2.24 RSc, and Celtig TIG16 are on the compatibility list.

Does the aquastat Ref. 60100606-30 being sold have one or two bulbs?

According to external sources identifying it as TC300001, a single bulb; the photo with a double bulb (TC30002) corresponds to another piece and is not representative.
