Fibaro control of Rain Bird 100-HV solenoid valve - coil heats up

The discussion revolves around controlling a Rain Bird 100-HV solenoid valve using a Fibaro double switch relay connected to a 230V power supply. The user reports that the solenoid coil heats up excessively, raising concerns about the compatibility of the 24V power supply, which is likely DC, with the valve designed for 24VAC. Participants suggest that a transformer with a capacity of at least 3A is needed for five valves, and emphasize the importance of using AC power to avoid overheating and buzzing noises. The user later connects a rectifier bridge, which alleviates the buzzing but raises questions about the appropriateness of this setup. The conversation also touches on the need for proper isolation of the Fibaro switch outputs and the potential for using a single transformer for multiple valves. Ultimately, the user seeks to ensure safe and effective operation of the irrigation system.
