Abstract

Abstract A temperature conditioning system has a temperature conditioning apparatus such as a heating apparatus or cooling apparatus, an air treatment for cleaning apparatus and a fan for moving air through the temperature conditioning apparatus and air treatment apparatus to supply the conditioning air to a space in which the temperature is controlled by a space thermostat connected to control the heating and cooling apparatuses. The space thermostat has a switch connected through a fan cycler to provide for cycling the fan independent of the operation of the heating and/or cooling apparatus to periodically move air through the air treatment apparatus and throughout the space to insure that the air is periodically treated and moved throughout the space to prevent stagnation when there is no call for operation of the heating and/or cooling apparatus.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 139 words
In a space forced air temperature conditioning system comprising: a thermostat mounted in a space in which the air is to be conditioned; air temperature conditioning apparatus remotely located from the space; circuit means connecting said thermostat to control the operation of said air temperature conditioning apparatus; air moving fan means connected to said conditioning apparatus for delivering temperature conditioned air through ducts to the space from said air temperature conditioning apparatus to maintain a desired temperature in the space as set by said thermostat; said air moving fan means normally being operated when said temperature conditioning apparatus is energized; cycling means connected to said air moving means and connected to be controlled by a switch on said thermostat to cycle said air moving means to periodically deliver air to said space when said conditioning apparatus is not operating.
Claim 2
Dependent Claim 139 words
In a space forced air temperature conditioning system comprising: a thermostat mounted in a space in which the air is to be conditioned; air temperature conditioning apparatus remotely located from the space; circuit means connecting said thermostat to control the operation of said air temperature conditioning apparatus; air moving fan means connected to said conditioning apparatus for delivering temperature conditioned air through ducts to the space from said air temperature conditioning apparatus to maintain a desired temperature in the space as set by said thermostat; said air moving fan means normally being operated when said temperature conditioning apparatus is energized; cycling means connected to said air moving means and connected to be controlled by a switch on said thermostat to cycle said air moving means to periodically deliver air to said space when said conditioning apparatus is not operating.
Claim 3
Dependent Claim 123 words
An improvement in a space temperature control system wherein a space thermostat controls a remote temperature conditioning apparatus to deliver temperature conditioned air by means of a fan to a space wherein there is a need to have movement of air in the space for comfort when normal operation of the fan is not taking place, the improvement comprising: manually operated switch means mounted on the space thermostat; cycling switch means connected to the fan to cycle the fan operation independent of the operation of the temperature conditioning apparatus; circuit means connected said manually operated switch means to said cycling switch means for cycling the fan to maintain movement of air in the space even though the temperature conditioning apparatus is not operating.
Claim 4
Dependent Claim 123 words
An improvement in a space temperature control system wherein a space thermostat controls a remote temperature conditioning apparatus to deliver temperature conditioned air by means of a fan to a space wherein there is a need to have movement of air in the space for comfort when normal operation of the fan is not taking place, the improvement comprising: manually operated switch means mounted on the space thermostat; cycling switch means connected to the fan to cycle the fan operation independent of the operation of the temperature conditioning apparatus; circuit means connected said manually operated switch means to said cycling switch means for cycling the fan to maintain movement of air in the space even though the temperature conditioning apparatus is not operating.
