REFRIGERATION CONTROLS
General Requirements: Rebates are available for installing controls on non-self-contained refrigeration equipment, either existing equipment or in conjunction with new equipment listed on this page. Controls costs must be itemized separately on invoice. Rebates are not available for replacing existing controls.
ANTI-SWEAT HEATER CONTROLS Requirements:
• Controls must be designed specifically as anti-sweat (anti-condensate) heater controls and must sense the relative humidity in the air outside of the display case and turn off the anti-sweat heaters at low humidity conditions. • Controls may be programmed in a larger store system, such as PMAC or EMS. If so, please include the system
information along with the options for anti-sweat heater controls denoted. • Must control heaters on rail (mullion) and door, if equipped with heater. Application Measure Description Code

DEMAND DEFROST CONTROLS Requirements: • Rebate is based on kW of electric defrost controlled. Please include the evaporator make and model information, along with the defrost controls make and model information on the application, invoice, or manufacturer specification sheet. • Electric defrost heater controls in coolers may be eligible for a custom incentive.

Include supporting documentation such as compressor make and model, spec sheet, or nameplate photos to confirm hp. • If the refrigeration system hp is unavailable, convert the low temperature (LT) and medium temperature (MT) systems’ rated cooling capacity in BTU/h using the following factors:
• LT hp = LT compressor capacity (BTU/h)/6,000 • MT hp = MT compressor capacity (BTU/h)/8,700
