QBK is fully confgurable: the same device can be used to control different types of gas and oil burners. Password is required to modify all parameters except for Communication settings.

Customers that want to modify the configuration can apply for specific agreement here. Once approved, all purchased units will have unique password assigned. Since a new label or remark must be placed on the unit when the original configuration is modified, this procedure is not recommended for occasional users.

Note on EC type-examination

Since EN 298 does not describe all functions of the QBK – implemented to manage all possible industrial scenarios – the operator is responsible for ensuring that parameters and functions are appropriate for the application.
Certification applies only for options and values allowed by EN-298.
