Pressure Transducer Inputs
The pressure inputs P1 and P2 (shown in previous figure) are designed for 3-wire pressure sensor
transducers, specifically Kavlico™ brand, which require 5 Vdc input.
Important: If using a different brand of pressure sensor transducer, contact Trane for help ensuring
proper operation.
• P1 is typically used alone in single-duct applications when only one pressure measurement is
needed.
• P1 and P2 are typically used together in dual-duct applications when two pressure measurements
are needed. Examples include dual-duct VAV control and duct pressure measurement.
Binary Inputs
Connect to the binary inputs to monitor statuses such as fan on/off or alarm resets. The illustration
below shows a typical wiring for binary inputs to either UI or BI terminals.
