Abstract
Abstract A method and control is provided wherein the sensors in a plurality of zones are properly associated with the dampers associated for each of the zones after installation. A technician goes to each zone and sends a signal from the sensor, and the control then makes a change at the associated damper. The technician can then ensure the two are properly associated within the control.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
154 words
A method of ensuring proper installation of an HVAC system comprising the steps of: (1) providing an HVAC system including a plurality of zones each having a damper and an associated sensor, and a control associating each of said dampers, with one of said sensors; (2) moving the control into a verification mode, and sending a signal from one of an associated set of a damper and a sensor at said control, said control then performing a change at the other of said associated sensor and damper to allow a technician to ensure said damper and sensor are proper, as associated within said control; (3) repeating step (2) at a second zone; (4) said technician sending a signal from said sensor, and said control changing the position of said damper based upon a receipt of said signal; and (5) said dampers of zones other than said first zone are maintained static during step 2.
Claim 2
Independent Claim
154 words
A method of ensuring proper installation of an HVAC system comprising the steps of: (1) providing an HVAC system including a plurality of zones each having a damper and an associated sensor, and a control associating each of said dampers, with one of said sensors; (2) moving the control into a verification mode, and sending a signal from one of an associated set of a damper and a sensor at said control, said control then performing a change at the other of said associated sensor and damper to allow a technician to ensure said damper and sensor are proper, as associated within said control; (3) repeating step (2) at a second zone; (4) said technician sending a signal from said sensor, and said control changing the position of said damper based upon a receipt of said signal; and (5) said dampers of zones other than said first zone are maintained static during step 2.
Claim 3
Dependent Claim
25 words
The method as set forth in claim 1 , wherein said dampers of zones other than said first zone are maintained closed during step 2.
Claim 4
Dependent Claim
21 words
The method as set forth in claim 1 , wherein said signal is sent by said sensor by actuating an input.
Claim 5
Dependent Claim
32 words
The method as set forth in claim 1 , wherein if the change at the other of said associated sensor and damper is not seen, an identification of a mis-wiring is made.
Claim 6
Independent Claim
150 words
A method of ensuring proper installation of an HVAC system comprising the steps of: (1) providing an HVAC system including a plurality of zones each having a damper and an associated sensor, and a control associating each of said dampers, with one of said sensors; (2) moving the control into a verification mode, and sending a signal from one of an associated set of a damper and a sensor at said control, said control then performing a change at the other of said associated sensor and damper to allow a technician to ensure said damper and sensor are proper, as associated within said control; (3) repeating step (2) at a second zone; (4) said technician sending a signal from said sensor, and said control changing the position of said damper based upon a receipt of said signal; and (5) said signal being sent from said sensor by disconnecting a wire.
Claim 7
Independent Claim
150 words
A method of ensuring proper installation of an HVAC system comprising the steps of: (1) providing an HVAC system including a plurality of zones each having a damper and an associated sensor, and a control associating each of said dampers, with one of said sensors; (2) moving the control into a verification mode, and sending a signal from one of an associated set of a damper and a sensor at said control, said control then performing a change at the other of said associated sensor and damper to allow a technician to ensure said damper and sensor are proper, as associated within said control; (3) repeating step (2) at a second zone; (4) said technician sending a signal from said sensor, and said control changing the position of said damper based upon a receipt of said signal; and (5) said signal being sent from said sensor by disconnecting a wire.
Claim 8
Dependent Claim
115 words
An HVAC system comprising: a plurality of zones each having a damper and an associated sensor, and a control associated with each of said sensors with one of said dampers; said control being movable into a verification mode at which it receives a signal associated with one of said sensors to indicate a location for an installation check, said control associating said signal from said one of said sensors with a particular damper, and changing the position of said damper to in turn allow a technician to ensure said sensor and said damper are properly associated at said control; and said signal being sent from said sensor by disconnecting a wire associated with said sensor.
Claim 9
Dependent Claim
115 words
An HVAC system comprising: a plurality of zones each having a damper and an associated sensor, and a control associated with each of said sensors with one of said dampers; said control being movable into a verification mode at which it receives a signal associated with one of said sensors to indicate a location for an installation check, said control associating said signal from said one of said sensors with a particular damper, and changing the position of said damper to in turn allow a technician to ensure said sensor and said damper are properly associated at said control; and said signal being sent from said sensor by disconnecting a wire associated with said sensor.
