UMA modules deliver on/off control for appliances, fan/pump motors and outdoor lighting transformers (see model UML, dimmer modules for incandescent lamp control). Installation is simple: the module is plugged into a standard 120 VAC outlet and the appliance or light to be controlled is plugged into the bottom of the module. The connected appliance can be manually controlled by a UPB switch or multi-button controller, or automatically with a scheduler (model UCS-01), I/O module (model UMI) or with any PC / security / home automation controller that provides a UPB serial driver software option (see Frequently Asked Question for a current listing).
The UMA-20-W includes a powerful timer option that can automatically turn off the controlled outlet after a preset period of: 1, 5, or 30 seconds; 1, 2, 4, 10, 20, 30, 40, or 50 minutes; 1,2, 3, or 4 hours. The timer can be disabled so the UMA-20-W functions like a standard appliance module (no timer function). A UPB switch, such as the US2-40, can command any of the UMA-20-W timer functions via lighting scene-link commands to enable any selection of the timed off options.
