Abstract: A networked heating, ventilation and air-conditioning (HVAC) system is provided. The networked HVAC system includes HVAC equipment deployed in a building and an element of HVAC equipment, which is communicatively coupled with the HVAC equipment to collect types of diagnostic information relating to the HVAC equipment. The element of HVAC equipment is normally operable in a normal mode and is selectively operable in a service mode. The normal mode is characterized in that diagnostic information is collected by the element of HVAC equipment at a first rate. The service mode is characterized in that diagnostic information is collected by the element of HVAC equipment at a second rate, which is greater than the first rate.

Abstract: Aspects of the present disclosure are directed to a multi-function cooking oven having horizontally and vertically oriented heating elements and cooking functions that configure horizontal and vertical position, horizontal and vertical rotation, radiation and superheated air circulation for cooking food within the oven enclosure. Cooking functions include horizontal rotisserie, vertical rotisserie, baking, warming, dehydrating, pizza, barbecuing, kebabs, toasting, boiling, and air frying. Depending on the cooking function, a timer is set for turning on and off the horizontally and vertically oriented heating elements and a fan providing heated airflow within the oven enclosure. The timer also controls rotation of a vertical axis turntable assembly and a horizontal spit assembly configured with or without a wire drum.
