Honeywell PCB Cointra Europa M 20 L Ref. V7726
The Honeywell Cointra Europa M 20 L PCB (control board) Ref. V7726 is a control module that regulates the ignition, burner modulation, pump, and safety features of the boiler. If this part fails, you will notice that the boiler does not start, locks out, or exhibits erratic behavior. It is compatible with the Europa M 20 L and M 20 L models, among others. It is recommended to replace it when you experience these symptoms to avoid further issues in the system.

How to check if the part number V7726 is the one 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 V7726. 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 V7726 PCB solves.
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 does not ignite or shows an ignition fault.
Cause: The PCB controls the ignition: it opens the gas, generates the spark, and checks the flame. If something goes wrong, it aborts the ignition.
Before changing the PCB, make sure that the ignition electrode and the ionization electrode are clean and properly positioned.
- 02
A fault related to the flow switch or the gas valve has occurred.
Cause: The PCB receives the signal from the flow switch and controls the gas valve; if it does not receive the signal correctly, it cuts off the gas for safety.
Check that there is enough water flow and that the flow switch is not stuck or dirty.
- 03
The temperature control is unresponsive: the water always comes out at the same temperature.
Cause: The temperature regulation stages adjust the power according to the setpoint; if they fail, the boiler does not modulate.
Before replacing, check the settings of the control and make sure that the temperature selector is not loose or damaged.
- 04
The module does not respond to changes from the remote control or the thermostat.
Cause: The PCB receives commands from the thermostat and the control; if the input fails, it ignores any external commands.
Bridge the thermostat terminals on the PCB to check if the boiler responds; if it does not react, the problem is with the PCB.
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.
