The RM7838A1014 from Honeywell’s 7800 Series functions as a microprocessor-controlled semi-automatic on-off burner control module. This component is a plug-in type designed to fit onto the Q7800A1005/Q7800B1003 wiring subbase for straightforward installation.
Under standard operating conditions, it can handle an input voltage of 120 VAC and operates effectively across frequencies of either 50 or 60 Hz. The temperature specifications for this module allow for extreme environmental adaptability, as it operates between -40°C and 60°C. When not in use, it remains safe and functional within a storage temperature spectrum from -40°C to 66°C.
Additionally, the device can tolerate humidity levels up to 85% RH without condensation, ensuring reliability in high-moisture environments. The maximum connected load that this unit can support is 2000 VA, and it has a maximum power dissipation rating of 10 watts. To protect the circuit, it is recommended to use a fast-blow fuse rated at 15A, specifically Type SC or an equivalent. The module is also rated for vibration exposure up to 0.5G, making it suitable for various installation locations.
