Scatola di comando Brahma 37100204 CM11F

Brahma CM11F is a modern “burner management unit” (burner control unit) for complete automation and control of intermittent‑cycle atmospheric gas burners. The CM11F model can work both with forced‑air burners (with a fan) and with burners without a fan. Purpose and applications The Brahma CM11F model is designed for controlling two‑stage atmospheric gas burners operating in intermittent (cyclic) mode. This high‑tech controller is used in a wide range of heat‑generating equipment: Heating and combination boilers. Hot air generators and hot air guns, including Master models BV70, BV110, BV170, BV290, B230, B360 and Oklima. Air heaters, radiant tube heaters, water heaters. Furnaces, combi steamers and other process equipment. Main specifications and functions Parameter Value Model Brahma CM11F Article numbers 37100204, 246.124.077 Burner type Two‑stage, atmospheric (with or without fan) Operating mode Intermittent (cyclic) Pre‑purge time (TW/TP) 1.5 seconds Safety time (TS) 5 seconds Waiting time (TW) 1.5 seconds Supply voltage 220‑240 V AC, 50/60 Hz, 7 VA Enclosure protection class IP00 (requires installation inside a protective cabinet/enclosure) Operating temperature –20 °C to +60 °C Dimensions (W×H×D) 107 × 81 × 36 mm Weight 0.17 kg Base included No (purchased separately) Service life > 250,000 cycles Standards compliance EN 298:1993, EN 298:2003, CE PIN 0694BR1154 Key features Reliable two‑stage burner control – The Brahma CM11F is designed for two‑stage burners, providing clear switching between power levels. Manual lockout reset – In the event of an abnormal situation, restarting the burner requires manually pressing the Reset button on the housing. This guarantees safety and prevents automatic start‑up. Ionisation flame control – The controller uses an ionisation electrode for flame detection, providing a response time on flame loss of less than 1 second. Important: The device has no protective resistance – touching the detection electrode is unsafe. Built‑in ignition transformer – Equipped with a high‑efficiency solid‑state ignition device, simplifying installation and eliminating the need for a separate ignition unit. Reliability and protection: Electronics protected against external influences; impact‑resistant housing. Built‑in varistor for protection against voltage surges. Built‑in electromagnetic interference (EMI) filter for stable operation and long service life. Auxiliary contact – For low‑power ignition or for controlling the main solenoid valve in systems with intermittent power supply. Installation and operation recommendations Mounting – Protection class IP00 requires the unit to be installed inside a protective cabinet or enclosure. Any mounting position is possible. Wiring – Strictly observe polarity when connecting live and neutral wires. Use a base, purchased separately. Molex connectors are provided for reliable connection. Maintenance – Regularly check the condition of the ionisation electrode and the reliability of connections. For stable operation it is recommended that the ionisation current be 3‑5 times higher than the minimum value (1.2 µA). Important: This unit is a critical safety component for gas equipment. Advantages of choosing Brahma CM11F Ideal compatibility – A specialised solution for gas two‑stage burners. Safety first – Manual reset eliminates the risk of automatic start‑up and meets the highest standards. Versatility – Suitable for a wide range of climate control and heat‑generating equipment. Quality and durability – More than 250,000 operating cycles, Italian quality of assembly and components. Order codes 37100204 246.124.077
