The transmitting device includes a connector for removably installing and connecting to electrical power in the vehicle and a transmitter for transmitting a signal to a remote receiver. The ECU comprises of an exterior control panel and microprocessor-based controller for operating environmental devices within a facility or other defined space. When the controller receives an input from any of the receiver and an external environmental device, it activates at least one of the environmental devices. When the controller receives any such input that is outside a predefined range, the controller generates any of a visual or audible alarm and notifies a predetermined recipient. ## Claims ### Claim 1 A transmitting device for installation in a vehicle and for signaling a receiver to activate an environmental control unit, comprising: a housing;
