Carte électronique (carte de commande) Honeywell SM07414

Honeywell SM07414U control board for Hermann Thesi gas boiler. Original electronic controller (BMBC CONTROLLER THESI 2 PMIX). The Honeywell SM07414U board is a specialized electronic control module designed for gas boilers. This device is also known under manufacturer part number 52005814 and in warehouse inventory systems as 534.568.033. The original BMBC Controller board provides full control over the heating system operation, fault diagnostics, and safe equipment operation. Purpose and compatibility: The SM07414U control board was developed by Honeywell engineers specifically for Hermann Thesi gas boilers. This controller (type BMBC CONTROLLER THESI 2 PMIX) is the "brain" of the heating system and is responsible for all key processes. The module is ideal for: Replacing a failed board: If the boiler does not start, displays an error, or operates unstably, electronics replacement is likely required. Planned maintenance: Creating a spare parts stock for service departments. Restoring operation of various Hermann Thesi boiler modifications. Functional capabilities: The original Honeywell SM07414U board performs critical functions ensuring stable and safe boiler operation: Gas supply control: Regulates fuel supply to the burner based on required temperature. Ignition control: Ensures correct flame ignition and monitoring. Sensor signal processing: Reads information from temperature (NTC), pressure, and water flow sensors, adjusting operating modes. Safety: Monitors emergency conditions (overheating, lack of draft, pressure drop) and automatically shuts down the boiler when faults occur, preventing serious damage. Pump control
