Boiler Reset Control
In stock
$0.00
This incentive is available for the addition of a supply temperature setpoint reset to natural gas boilers, allowing the boiler supply temperature setpoint to decrease by at least 20°F based on heating demand, such as zone demand or outside air (OA) temperature. There is also a Retro-commissioning (RCx) option for existing boilers with unused reset capabilities to optimize their operation according to the same criteria.

Required Documentation:
• Boiler input capacity, such as a nameplate picture and boiler specifications.
• HVAC control documentation: BAS graphic screenshots, control programming, sequence of operation, functional testing documentation. Confirm existing control: Fixed boiler setpoint.
• RCx option proof: Show reset control not functioning as described. (e.g., the setpoint may reset, but the supply temperature isn’t controlled accordingly).
• Post-implementation evidence: Boiler setpoint reset based on heating demand or outside air temperature. Requirement: Setpoint decreases by ≥20°F during reduced heating demand. Independent variable specification: Zone demand, outside air temperature. Example: Initial control fixed setpoint 180°F, minimum reset temperature ≤160°F.
Important Consideration:
• RCx option: Incentive only available every 15 years
• Applicability: Eligible for new construction and retrofit projects
• Baseline: The existing boiler must have a fixed supply temperature setpoint without the capability to adjust based on heating demand or outdoor temperature (except for the RCx option).
• Exclusions:
- Redundant boilers.
