it is designed for globe valves like the VB-7000 series and can be adapted for damper control using the appropriate AM-601 linkage kits

this DSI control board utilizes a microprocessor to ensure precise timing and diagnostic LED feedback for troubleshooting

Pressure Integrity: Designed to maintain a reliable seal under significant system pressure fluctuations

this is a 208/230V 1-Phase motor

the 120VAC coil is housed in a NEMA 4X enclosure

Resideo CPR8 Regulator 321702-401 it is designed for globeThe 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
