摘要:
The disclosure includes an HVAC data processing and communication network and a method of manufacturing the same. In one embodiment the network includes a duct, a blower and a controller. The blower is configured to receive a control message from a data bus. The duct is configured to direct air flow from the blower. The controller is configured to publish the control message to the data bus. The controller thereby commands the blower to provide air to the duct at an initial volume rate and to increase the volume rate until the controller detects onset of a cutback mode of the blower.

The invention relates to a film having two major, opposing surfaces and impressments at both opposing surfaces. The film is useful as a liner, especially a waterproof liner such as a shower pan liner. The impressments take the form of at least a line, an indicium, or both. The lines can be rectilinear, curvilinear, or a combination of both in random or organized segments and can be measured in any system of units or combination of units. The indicia impressed at each surface of the waterproof liner can be in the same or different languages.

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.

An apparatus for checking conditioning mode of a heat pump system includes: (a) a temperature sensing device coupled with the heat pump system at a sensing locus; (b) a comparing device coupled with the temperature sensing device and configured for comparing a first temperature sensed by the temperature sensing device at a first time with a second temperature sensed by the temperature sensing device at a second time to determine an extant conditioning mode; the extant conditioning mode being a first conditioning mode when the second temperature is greater than the first temperature; the extant conditioning mode being a second conditioning mode when the second temperature is less than the first temperature.
