The RM7845A1001 from Honeywell belongs to the 7800 Series and serves as an advanced automatic burner control unit. Constructed around a microprocessor, this device is engineered for optimal performance in demanding environments. It achieves flame establishment in a maximum of 10 seconds, ensuring timely ignition. The voltage rating for this unit is 120 VAC, and it accommodates input frequencies of 50 or 60 Hz.

Operating conditions are critical, and this module satisfies a broad range, functioning efficiently between -40°C and 60°C. For storage, it can endure temperatures from -40°C to a maximum of 66°C. Additionally, this unit operates effectively in humid environments with up to 85% relative humidity, as long as conditions are non-condensing.

The maximum connected load that the RM7845A1001 can support is 2000 VA, while the device itself has a power dissipation of not more than 10 watts. To ensure safety, it incorporates fusing rated at a maximum of 15A, and it requires a Type SC or a similarly rated fast-blow fuse. This control unit is suitable for vibration environments rated up to 0.5G.

Installation is simplified, as the module is designed for plug-in mounting on Q7800A or Q7800B wiring subbases. Additionally, it offers flexibility in flame initiation, allowing for a pilot flame establishing period of either 4 or 10 seconds, thus adapting to various operational requirements.
