Replacement Options for ERM-FLU
Issue
ETC has discontinued the ERM-FLU as of May 5th, 2026. If you experience a failure of these devices after existing stock has run out, there are a few options for replacement, depending on the use case and available space. The main factors that will affect what kind of controller you should replace with are going to be available space for the controller and load amperage.
Plug Loads
Plug loads can vary heavily in amperage; a household vacuum cleaner can pull up to 12 amps (A), depending on the as such, an ELED1 or ELEDR is not going to be a suitable replacement. The best controller for a plug load will be the ERNR (15A max load) . These controllers also have an auxiliary out to control a second, non-switched plug load.
Consistent Loads
For a load that will not experience regular changes in amperage (i.e. most things not connected to a wall outlet), the main limiting factor is available space. The ELED1 is the most similar in size to an ERM-FLU if the device needs to fit in a smaller space, but its relay is only rated to 11.5A. If your load is higher amperage, you will need to use an ELEDR, which is rated to 16A for an electronic ballast or LED driver and 20A for a magnetic ballast and other standard loads.
