Cotherm SBSC0077 Aquastat For Boiler CTVOL 804416D D06 TR And Compatible Models
If you notice that your boiler is not regulating the temperature properly or is blocking due to a false pressure loss, you may need the Cotherm SBSC0077 aquastat for the CTVOL 804416D D06 TR boiler and compatible models. This part measures and controls the pressure and temperature of the circuit, ensuring proper system operation. It is installed in boilers from the CTVOL range, among others like the GCR 502724D E31 EC and GCV 3035 16D D06 TS2R models. It is advisable to replace it when the readings are incorrect, as this can affect the performance of the boiler.

How to check if ref. SBSC0077 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 SBSC0077. 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 SBSC0077 resolves.
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 stops or locks out for no apparent reason, with no leaks or visible flame failure.
Cause: The aquastat detects an incorrect temperature or the contact does not close properly, and the control board shuts off for safety.
Check that the capillary bulb is properly inserted in its sleeve and in good contact, not loose or displaced.
- 02
The water in the circuit does not reach the set temperature even though the burner ignites normally.
Cause: The aquastat contact does not properly close the heat demand, so the control board does not receive the order to continue heating.
With a multimeter, measure the continuity of the contact while varying the temperature before replacing the part.
- 03
An error or interruption appears on the display related to the temperature sensor.
Cause: The damaged or disconnected capillary bulb sends an incorrect reading to the control board.
Visually check that the capillary is not bent, broken, or disconnected from the bulb.
- 04
The boiler heats intermittently, starting and stopping without any change in demand.
Cause: False contact in the water heater that causes the signal to be lost and recovered on its own.
With the boiler running, carefully move the aquastat connector to see if the fault repeats when you touch it.
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.
