The Copeland 943-0120-00 SecureStart Module Kit is a field-proven soft start controller designed specifically for single-phase compressors in residential and commercial HVAC units

For technicians troubleshooting intermittent lockout codes or high-resistance readings at the sensor probe

this component features tin-plated brass quick-connect terminals for reliable signal transmission and is a direct factory update for older SWT2685 and SWT-2685 variants often found in AUC and TUC furnace series

Dwyer Instruments 2002 Pressure Gage 321042-401 always refer to the schematicThe Dwyer 2002 Magnehelic Gage is the industry standard for monitoring differential pressure in commercial HVAC systems, cleanrooms, and air handling units. Specifically calibrated for a range of 0 2. 0" w. c., this diaphragm actuated gage provides high precision monitoring of air and compatible non combustible gases with an accuracy of 2% of full scale. The friction free Magnehelic movement utilizes a high torque magnetic linkage rather than
