Systems and methods for provisioning a component of an HVAC system are presented. A provisioning device, such as a smartphone, is used to scan HVAC component information obtained from a tag on each component and wirelessly transfers the information to a thermostat or HVAC system controller. The thermostat or system controller automatically configures itself to control the equipment based on the details in the tag which are transmitted to the thermostat. The label may include barcode or textual information, which is decoded by software executing in the provisioning device, the thermostat, or a server computer in communication with the provisioning device or the thermostat. In embodiments, the HVAC component information is transmitted to a web services application to facilitate the installation, support, maintenance, and repair of the HVAC system.

A temperature control apparatus is provided, which is capable of, even when it is necessary to perform control by means of valves in a plurality of channels, promptly controlling a temperature of an area to be temperature-controlled promptly to a desired temperature, while avoiding complication and enlargement of the apparatus as a whole. Passage and blockage of a heating medium passing through a first supply channel to a mixing channel, a temperature of the heating medium being controlled by a first temperature regulating unit at a predetermined temperature, and passage and blockage of a heating medium passing through a second supply channel to the mixing channel, a temperature of the heating medium being controlled by a second temperature regulating unit, are controlled by a valve unit. The valve unit includes a first spool valve and a second spool valve, which are coupled through a heat insulating layer.
