CONTROLS
ADVANCED ROOFTOP UNIT CONTROLLERS Requirements:
• Rooftop units must be constant volume with single speed supply fan and have direct expansion cooling with heating. Rooftop units must also have a functioning economizer, have a ≥ 1.0 hp supply fan, and have ≥ 7 nominal tons of cooling. • The existing rooftop unit must serve a space occupied at least 1,500 hours per year. • Advanced rooftop unit controllers must provide: • Multispeed or variable speed control of the supply fan. • Modulating outdoor air damper control to maintain proper ventilation rates according to Wisconsin Commercial Building Code under different fan speeds. • Demand control ventilation (DCV) to modulate outdoor air supplied to the building. • Integrated economizer functionality (stages on and off as needed). • Projects applying for advanced rooftop unit controls cannot also apply for rebates for DCV and variable frequency drives. • Rebate is available for installation of advanced rooftop unit controllers on existing units or for new replacement rooftop units on existing buildings. Advanced rooftop unit controllers are not eligible when installed on a new replacement rooftop unit if the old rooftop unit had advanced rooftop unit controls. • A list of qualified advanced rooftop unit controllers can be found on focusonenergy.com/qpls. If a proposed advanced rooftop unit controller solution is not on the qualified products list, contact Focus on Energy prior to initiating the project to confirm the solution will qualify.
