Resideo CPR8 Regulator 321702-401 the Nordyne 491226R 8KW HeaterThe Resideo CPR8 Regulator is a critical replacement component for the CPRD8 bypass damper system, engineered to manage pressure fluctuations in constant volume and variable air volume HVAC systems. Designed for heavy duty zoning bypass control, this regulator ensures the barometric damper maintains appropriate static pressure as zone dampers open and close. By utilizing a precise weighted pressure regulator mechanism, the CPR8 prevents excessive air
