One aspect of the disclosure describes a controller for a heating, ventilation, and air conditioning (HVAC) unit. In one embodiment, the HVAC controller includes an interface and a processor. In this embodiment, the interface is configured to receive a delay originating signal. In one embodiment, the processor is configured to: (1) automatically generate an offset delay value for the HVAC unit upon receipt of the delay originating signal; (2) apply the offset delay value based on an offset enabled configurable parameter; and (3) delay starting identified components of the HVAC unit based on the offset delay value.

1. A controller for a heating, ventilating and air conditioning (HVAC) unit, comprising: an interface configured to: receive an originating signal, the originating signal indicating that a component of the HVAC unit requires starting;receive an offset enabled configurable parameter, the offset enabled configurable parameter associated with a plurality of events for which delayed starting of the component of the HVAC unit is enabled;receive a notification of an event associated with the originating signal; anda processor communicatively coupled to the interface, the processor configured to: automatically generate an offset delay value for the HVAC unit upon receipt of the originating signal;apply the offset delay value based on the offset enabled configurable parameter and the event associated with the originating signal; anddelay starting the component of the HVAC unit based on the offset delay value. 2. The HVAC controller as recited in claim 1 wherein the plurality of events include a processor reset due to loss of network communications, or a network command. 3. The HVAC controller as recited in claim 1 wherein a user can set the offset enabled configurable parameter so that no events will delay starting the component of the HVAC unit. 4. The HVAC controller as recited in claim 1 wherein the offset enabled configurable parameter is a factory default setting. 5. The HVAC controller as recited in claim 4 wherein the factory default setting for the offset enabled configurable parameter includes power-on-reset (POR) and coming-out-of-night setback events. 6. A method for starting a heating, ventilating and air conditioning (HVAC) unit, said method comprising: receiving an originating signal at a controller for the HVAC unit, the originating signal indicating that a component of the HVAC unit requires starting;receiving an offset enabled configurable parameter, the offset enabled configurable parameter associated with a plurality of events for which delayed starting of the component of the HVAC unit is enabled;receiving a notification of an event associated with the originating signal;automatically generating an offset delay value for the HVAC unit based upon receipt of the originating signal;applying the offset delay based on the offset enabled configurable parameter and the event associated with the originating signal; andstarting the component of the HVAC unit based on the offset delay value. 7. The method as recited in claim 6 wherein the plurality of events include a processor reset due to loss of network communications, or a network command. 8. The method as recited in claim 6 wherein a user can set the offset enabled configurable parameter so that no events will delay starting the component of the HVAC unit. 9. The method as recited in claim 6 wherein said offset enabled configurable parameter is a factory default setting. 10. The method as recited in claim 9 wherein the factory default setting for the offset configurable parameter includes power-on-reset (POR) and coming-out-of-night setback events. 11. A heating, ventilating and air conditioning (HVAC) system, comprising: a first and second HVAC unit, each HVAC unit including: a refrigeration circuit having at least one compressor, a corresponding evaporator coil and a corresponding condenser coil;an indoor air blower configured to move air across the evaporator coil;an outdoor fan configured to move air across the condenser coil; anda controller coupled to the refrigeration circuit, the indoor air blower and the outdoor fan, the controller having:an interface configured to: receive an originating signal, the originating signal indicating that a component of the first HVAC unit requires startingreceive an offset enabled configurable parameter, the offset enabled configurable parameter associated with a plurality of events for which delayed starting of the component of the first HVAC unit is enabled;receive a notification of an event associated with the originating signal; anda processor communicatively coupled to the interface, the processor configured to: automatically generate an offset delay value for the first HVAC unit upon receipt of the originating signal;apply the offset delay valued based on the offset enabled configurable parameter and the event associated with the originating signal; anddelay starting the component of the first HVAC unit based on the offset delay value, wherein an offset delay value for the first HVAC unit differs from an offset delay value for the second HVAC unit. 12. The HVAC system as recited in claim 11 wherein the plurality of events include a processor reset due to loss of network communications, or a network command. 13. The HVAC system as recited in claim 11 wherein a user can set the offset enabled configurable parameter so that no events delay starting the component of the HVAC unit. 14. The HVAC system as recited in claim 11 wherein the offset enabled configurable parameter is a factory default setting. 15. The HVAC system as recited in claim 14 wherein the factory default setting for the offset enabled configurable parameter includes power-on-reset (POR) and coming-out-of-night setback events.
