Description

Honeywell RM7850A1001/U is an automatic burner control unit. It manages the burner's operating sequence, supervises the flame, and provides system status indication via five LEDs. The controller performs self-diagnosis and fault detection, and supports external voltage monitoring. It operates on 220–240 V at 50–60 Hz, with a power consumption of 10 W and an external fuse rating of 20 A. Startup and purge times are each 2 seconds.

Vibration	0.5G in the immediate environment

Choosing and fitting

When selecting a replacement for this series, confirm that the mounting base has 22 pins. The controller uses interchangeable removable flame signal amplifiers, so the amplifier type must match the controller. Also verify that any peripheral modules (purge timer, network interface, etc.) are compatible with the controller. Overall thickness may vary depending on the base model used, so measure the available space.
