2024 HVAC Catalog

VARIABLE SPEED PUMP WITH ELECTRONICALLY COMMUTATED MOTOR (ECM) Requirements: • Variable speed electronically commutated motor (ECM) pumps are for the replacement of constant speed permanent split capacitor (PSC) motor pumps. • Pump may replace domestic hot water recirculation pumps, heating hot water circulation pumps, cooling water circulation pumps, and/or water loop heat pump circulation loops. • Existing pumps being replaced may be continuous run, timer controlled or controlled by aquastat temperature sensor. • New pump speed must be automatically controlled by differential pressure, flow, temperature or other variable signal. • For new construction projects, variable speed pumps that are required in accordance to International Energy Conservation Code 2015 are not eligible. For HVAC applications, this includes: • Variable speed drives for HVAC pump systems are required by code for hydronic HVAC systems greater than or equal to 300,000 BTU/hr. Variable speed drives on pump motors for hydronic systems ≥ 300,000 BTU/hr DO NOT qualify for incentives.

• For other HVAC VFD systems and larger motors, please see Variable Frequency Drives (VFD) in the previous section. • For constant torque VFD incentives, please see the variable frequency drive section of Process Systems Incentive Catalog. • Variable speed ECM pumps used for industrial process incentives may qualify for a custom incentive.
