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

1. 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.

2. The method as set forth in claim 1, wherein said dampers of zones other than said first zone are maintained closed during step 2.

3. The method as set forth in claim 1, wherein said signal is sent by said sensor by actuating an input.

4. 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.

5. 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.

6. 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.
