Auxiliary PCB CP16.01 Demrad Aden / Heatline Ref. 3003200183
The auxiliary PCB CP16.01 from Demrad Aden / Heatline is a fundamental component that controls the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, lock out, or operate erratically. The user may notice error messages such as "Err: User interface failure (PCB/keyboard-display) or its communication with the main board" or "F70: User interface incompatible with the main board." This board is compatible, among others, with the Heat Line HK V 124 boiler. It should be replaced when the mentioned symptoms occur.

How to check if ref. 3003200183 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 3003200183. 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 PCB 3003200183 resolves.
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler ignites and heats, but the domestic hot water doesn't reach or comes out cold.
Cause: The auxiliary PCB manages the switch to the domestic hot water circuit; if it fails, this function is lost without affecting the heating.
Check if the fault occurs only when opening the hot water tap and not when requesting heating, before replacing this PCB.
- 02
The display shows a code that the manual associates with an auxiliary component (pump, valve, secondary sensor).
Cause: This PCB manages additional functions, and a fault can be interpreted as a failure of that component.
Check the connector between the main PCB and this auxiliary one, ensuring that it is not loose or corroded, before replacing it.
- 03
The boiler operates normally most of the time, but it always fails at the same point in the cycle.
Cause: An intermittent fault in the electronics of this PCB always interrupts the same stage of the process.
Note the exact moment it fails (when starting, when modulating, when stopping); this helps to confirm the diagnosis before replacing it.
- 04
After a power outage or a power surge, the boiler stops responding normally.
Cause: The electronics of these auxiliary PCBs are sensitive to voltage spikes and can be damaged without leaving visible marks.
Cut the power to the boiler for a couple of minutes and restore the power before assuming that the PCB is dead.
Fault codes for Airsol that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| Err | User interface fault (PCB/keypad-display) or its communication with the main board. | The Auxiliary PCB (user interface) fails or loses communication with the main PCB. Check the wiring/connector between the interface and the main PCB; if the issue persists, replace the interface. |
| F70 | User interface incompatible with the main PCB. | An incompatible Auxiliary PCB has been installed or with incorrect DSN/coding. Check that the DSN/code on the display matches that of the boiler and the installed reference; correct the coding or replace the interface with the appropriate 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.
