The assembly typically includes the connector housing and internal terminal seating designed for standard gauge HVAC control wiring

Does this thermostat require a common wire (C-wire)

Use a jumper across the Speedup pins on the board

This high-speed performance ensures the forced-air induction required for complete combustion

The minimum speed is factory-calibrated via the start voltage

Trane CNT3159 Pressure Switch 319848-301 The assembly typically includes theThe Trane CNT3159 Pressure Switch is an essential high pressure cut out designed for precise refrigerant circuit monitoring in residential and light commercial HVAC units. This SPNO (Single Pole Normally Open) switch serves as a critical safety component, engineered to open the circuit when system pressure reaches 400 PSI and reset upon falling to 250 PSI. Built for compatibility with modern high pressure refrigerants like R 410A, the CNT3159 prevents
