Abstract

This disclosure is directed to an electronic thermostat for a heating, ventilation, and air conditioning (HVAC) system that includes an electronic level feature and leveling register that allow the thermostat housing to be rotated about a mounting wall plate to place the thermostat housing in a leveled position. In one aspect, the thermostat includes at least one accelerometer. Other systems and methods are disclosed.

Abstract

In various implementations, a multi-burner head assembly may include a venturi inlet coupled to burner heads. The multi -burner head assembly may allow control of the flame profile generated by the assembly. For example, burner heads of the multi-burner head assembly may include different characteristics, such as height.

IPC Classes  ?

• F23D 14/10 - Premix gas burners, i.e. in which gaseous fuel is mixed with combustion air upstream of the combustion zone induction type, e.g. Bunsen burner with elongated tubular burner head
• F23D 14/58 - Nozzles characterised by the shape or arrangement of the outlet or outlets from the nozzle, e.g. of annular configuration
• F27D 99/00 - Subject matter not provided for in other groups of this subclass

Abstract

In various implementations, a condition of a motor may be monitored based at least partially on time required to achieve a change in speed. A notification may be transmitted based on the condition of the motor.
