Baxi Roca R 30/30F Control Electronic Module Ref. 122122200
Control electronic module for Baxi Roca boilers R 30/30F. It is printed with the code E960421H / 12.201.03A and the Roca logo engraved on the copper of the circuit, so the PCB is manufactured by Baxi Roca. The transformer block mounted on it is from the brand AVISOR, not from Roca. It is replaced when the control module stops functioning.

How to check if ref. 122122200 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 122122200. 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 122122200 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 shows no signs of life: no indicators, no display, and the fan does not start.
Cause: The control module is the one that manages the entire startup; if it is dead, the boiler remains completely silent.
Check that power is reaching the boiler and that the main fuse of the installation is not blown.
- 02
The boiler starts and shuts down by itself after a few minutes, with no visible mechanical cause.
Cause: An intermittent fault in the module can cause it to lose the reading from the sensors or restart by itself halfway through the cycle.
Before changing the module, check that the sensor connectors and wiring are not loose or corroded.
- 03
The control or panel of the boiler does not respond to any commands, even though the display remains lit.
Cause: The entire control of the boiler goes through this module; if it fails, it stops responding even though it seems there is power.
Disconnect and reconnect the flat connector between the panel and the module before declaring the PCB faulty.
- 04
The boiler works intermittently, as if it is losing and regaining power sporadically.
Cause: The transformer block mounted on the module (from the brand AVISOR, not Roca) powers the electronics; if it fails, the PCB experiences intermittent power loss.
Measure with a multimeter if the transformer delivers current steadily before considering the complete PCB as good.
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.
