An indoor environmental conditioning system and a method for controlling the circulation of non-conditioned air. The system comprises a conditioning source, air distribution source and air distribution conduit. The air may be propelled at at least two different flow rates.

Indoor environmental conditioning system and method for controlling the

An apparatus and method for preparing an indoor environmental conditioning system for spaces, for operation. The apparatus and method are advantageously configured for use with an indoor environmental conditioning system in which the spaces are provided with an indoor environmental conditioning input and an indoor environmental conditioning sensor, both operably connected to an indoor environmental conditioning source. Each space is further provided with means for actuating the indoor environmental conditioning source. The apparatus and method enable the indoor environmental conditioning system to be placed in an initial condition such that no space can receive, and no sensor report, indoor environmental conditioning. The indoor environmental conditioning inputs are actuated one at a time, and operably linked thereafter with the indoor environmental conditioning sensor which reports a change in environmental conditioning status.

Installation link-up procedure

A control system for a fluid-fuel burner, such as a furnace for an HVAC system. The furnace has a variable flow of fuel into the burner. In addition, the circulating air blower is also variable. The furnace heat exchanger plenum is maintained at a substantially constant temperature, as a means for providing substantially constant temperature air to the spaces to be heated.

Control methods and apparatus for gas-fired combustors

A method and apparatus for controlling the circulation of heat transfer fluid for thermal conditioning systems for spaces, in which the temperatures of several at least partially thermally separate spaces are monitored and averaged, and compared with a predetermined set point temperature, for purposes of controlling the operation of a source of thermal conditioning. In addition, the temperature differentials between the several spaces are also monitored, for purposes of controlling the circulation of the heat transfer fluid. The present invention permits the continued circulation of the heat transfer fluid, even if no heating or cooling is required, for purposes of reducing the temperature differentials between the several spaces.
