The Honeywell RM7890B1048 belongs to the 7800 Series and functions as an advanced microprocessor-based primary burner control module. This device weighs 1.83 lbs and is designed for automatic control in various applications. Operating at a voltage of 120 V AC, it supports input frequencies of 50 or 60 Hz, making it adaptable for different installations.

With a robust operating range, the module handles minimum temperatures as low as -40 °C and can function up to a maximum of 60 °C. Nonvolatile memory is integrated to ensure that essential data is retained even after power interruptions. This burner control module utilizes an intermittent pilot flame, with the flame establishment period adjustable between a fixed 4 seconds or 10 seconds, according to the specific application needs.

The main flame is established intermittently, providing a reliable response in line with operational requirements. This module features shutter drive capabilities and supports valve proving when paired with the S7800A1142 module for programming. For operational status monitoring, the RM7890B1048 includes five LED indicators, with the power LED blinking fault codes during lockout conditions, offering clear visibility into system status and indicating any issues that arise.
