Abstract: A heating and cooling system for use with hot, cold and source fluid circuits. A conduit module couples a heating/cooling module with the fluid circuits. The conduit module includes four three-way valves to communicated fluid from and to the fluid circuits to first and second heat exchangers in the heating/cooling module. The first heat exchanger is used to heat a fluid flow and the second one chills a second fluid flow. The conduit module simultaneously supplies a hot fluid flow to a hot fluid circuit and a cold fluid to a cold fluid circuit. The source fluid is routed by the conduit module. A method of circulating fluid is also disclosed.

The system includes a power-in assembly, a trailer connection assembly and a breaker assembly that can be tailored to the particular electrical distribution needs of the RV. The trailer connection assembly includes a plurality of electrical terminals for engagement to wires connected to electrical components of the towing vehicle, such as brake lights, turn signal lights, etc. The breaker assembly includes a plurality of circuit breakers or fuses connected to the power-in assembly and to a plurality of corresponding output bars with output terminals to connect to the cables/wires for the auxiliary electrical devices. The system can include an auxiliary circuit for connection to an auxiliary power source, such as a solar panel array.

Abstract: A method of operating a heating and cooling system includes (1) providing a heating and/or cooling apparatus having first and second heat exchangers, (2) providing a conduit module modularly coupled to the heating and/or cooling apparatus and adapted to be coupled to a plurality of fluid circuits for heating or cooling loads, and (3) operating a control system configured to operate the conduit module in a heating or cooling mode. The conduit module is positioned between the heating and/or cooling apparatus and the plurality of fluid circuits. The conduit module includes first, second, and third supply conduits and first, second, and third return conduits, to convey first, second, and source fluids to and from respective first, second, and source fluid circuits. The conduit module includes first, second, third, and fourth three-way valves to selectively regulate flow of the first, second, and source fluids.

Abstract: In order to configure and monitor the operation of a span-powered T1 radio, use is made of the out-of-band facility data link channel that is available within an extended superframe of the T1 digital data stream transported between an indoor carrier services unit and the T1 framer of the radio. The facility data link channel is employed to transport packetized configuration and status information between the indoor carrier service unit and the span-powered T1 radio.
