Please note Touch/Remotes do not dim wire-wound low voltage transformers, choose the Intelligent Dimmer (IQ Dimmer) or alternatively look at the 630 Watt Low Voltage Standard Dimmer to dim this type of transformer. The Touch/Remotes also do not dim fans and inductive loads, choose the Intelligent Dimmer (IQ Dimmer) or look at Fan Regulators for these awkward loads, [please check with manufacturer that appliance is dimmable].
