Abstract: A method of configuring a control schedule for an environmental control system using a control device is disclosed. The control device has a display and a directional input element such as a rotary dial. The method involves performing a time period configuration process for a sequence of time periods. A time period is added to the control schedule and a representation of the added time period is displayed. In response to directional activation of the directional input element, a duration of the added time period is adjusted, with the representation being updated to indicate the adjusted duration. The adjusted duration is stored in response to a confirmation input signal. The time period configuration process is repeated until it is determined that no more time periods are to be added to the control schedule.
Abstract: A battery-powered environmental control and/or sensor device is disclosed. The device includes a mounting plate arranged to be affixed to a support surface; and a main body including a battery compartment. The main body is adapted to be releasably secured to the mounting plate, with the battery compartment being substantially inaccessible when the main body is secured to the mounting plate. The mounting plate and main body comprise complementary securing elements arranged to secure the main body to the mounting plate. The mounting plate or the main body include a lever having a portion extending beyond a periphery of the device so as to be operable by a device user when the main body is secured to the mounting plate. The lever is operable when activated to disengage the complementary securing elements and separate the main body from the mounting plate to provide access to the battery compartment.
