Honeywell Pressure Switch C6065A1226 For Neckar Bosch Novastar New 24 AE Boiler
Pressure switch model C6065A1226, manufactured by Honeywell (engraved on the body as Yamatake-Honeywell) and made in Japan. It has a setting of 0.65 mbar (maximum 6 mbar) and contacts of 1.5(0.5)A at 250V~, complying with the DIN-DVGW 88.06 b 050 standard. It cuts the circuit if the pressure goes out of that range. The batch read on the label is 9404DYM. Compatible with the Neckar Bosch Novastar New 24 AE boiler.

How to check if ref. 87161461360 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 87161461360. 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 that require diagnosis in the pressure switch 87161461360
The pressure switch controls the air or water pressure to authorize operation. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler tries to ignite and quickly shuts off, without heating.
Cause: The pressure switch does not close the contact properly and the control board cuts off the gas supply.
Check that the extractor is working properly and without obstructions before inspecting the pressure switch.
- 02
It is necessary to turn the boiler off and on several times for it to start.
Cause: An unstable closing pressure switch causes intermittent lockouts that are temporarily resolved by resetting.
With the boiler on, use a multimeter to check if the pressure switch contact remains closed steadily.
- 03
The boiler takes longer than usual in the pre-ignition phase, as if it hesitates.
Cause: The pressure switch takes time to close because the air pressure signal is weak or irregular.
Check that the air intake and flue gas outlet ducts are clean and free of obstructions.
- 04
The fault occurs especially on very windy days or with a long flue.
Cause: External conditions affect the pressure that the pressure switch receives, which may be right at the limit of its adjustment.
Note if the problem occurs on windy days before considering that the pressure switch is faulty.
Neckar fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| C1 | The pressure switch has activated during operation. | The air pressure switch detects a loss of depression/draft (obstruction in venturi/hoses or fatigued diaphragm) and opens the circuit; check continuity in COM/NO while the fan starts and inspect connections, tubes, and venturi. |
| C4 | The pressure switch does not open in the rest position. | The pressure switch contact remains closed at rest due to a stuck diaphragm or blocked tube; check with a multimeter that the micro switch opens without depression and clean/renew hoses and connection to the venturi. |
| C6 | The pressure switch (differential) does not close. | With the fan running, the minimum depression is not reached due to lack of draft/obstruction or a misadjusted/faulty pressure switch; measure the electrical closure of the micro when applying depression and check the flue, venturi, and tubes. |
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.
