Question 1

How do I know if this PCB is for my boiler?

Accepted Answer

Verify the reference H052005326 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.

Question 2

What is it used for?

Accepted Answer

The PCB controls the ignition, modulation, sensor readings, and safety features of the boiler.

Question 3

Is the boiler not igniting, locking out, or is the control board unresponsive?

Accepted Answer

After ruling out mains voltage, fuse, and connectors, a damaged PCB causes lockouts, blackouts, or erratic display. Repair the external cause before installing the new one.

Question 4

Which models is it suitable for?

Accepted Answer

Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.

Question 5

Installation and recommendations

Accepted Answer

After installation, a technician must adjust the service parameters (type of gas, power settings) and check combustion and safety features.

Question 6

What does refurbished mean and what coverage does it have?

Accepted Answer

Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.

Question 7

What does fault code F.61 mean in Renova?

Accepted Answer

Fault: gas valve control The PCB governs the coils of the valve; if the driver/output on the board fails, a control error is detected. Check voltage and continuity to the valve and, if correct, replace the PCB.

Question 8

What does fault code F.62 mean in Renova?

Accepted Answer

Error: gas valve disconnection controller The valve control circuit is on the PCB; a fault in that stage may leave the valve powered or cut off late. Check electrical closure after demand and, if wiring/valve are OK, replace the PCB.

Question 9

What does fault code F.63 mean in Renova?

Accepted Answer

Error: EEPROM The EEPROM memory is integrated into the PCB; data corruption or memory IC failure triggers this code. Verify with parameter reset (d.96) and, if it reappears, replace the PCB.

Question 10

What does fault code F.64 mean in Renova?

Accepted Answer

Error: electronics / sensor / analog to digital transformer The A/D converter and its inputs (NTC) reside in the PCB; if this electronics fails, F.64 is registered. Check NTC/wiring; if they are correct, the cause is the PCB.

Question 11

What does the fault code F.65 mean in Renova?

Accepted Answer

Error: electronics temperature too high The thermal sensor on the PCB detects overheating or the circuit is faulty. Check for external causes (heat/ventilation) and, if it persists without reason, replace the PCB.

Question 12

What does the fault code F.67 mean in Renova?

Accepted Answer

Incorrect value returned by ASIC (flame signal) The ASIC on the PCB interprets ionisation; if the ASIC/flame channel fails, F.67 appears. Check for the presence of flame and grounding; if they are correct, the PCB is the cause.

Question 13

What does the F.70 code mean in Renova?

Accepted Answer

Invalid product code (DSN) The DSN/coding reside in the PCB; if the display and PCB are changed without readjusting the DSN, F.70 will trigger. Check and reprogram DSN according to the manual; if not corrected, recode or replace the PCB.

Question 14

What does the Connection code mean in Renova?

Accepted Answer

No communication between the main PCB and the user interface. The PCB manages communication with the UI; a bus/driver fault on the board triggers this alarm. Check connectors X32/X35 and 24 V; if the wiring is fine, replace the PCB.
