This is the Variable-Voltage, Variable Frequency (VVVF) power supply for the blower motor.  This was donated to UTC by PEC (Process Engineering Company), now a division of Wood's.

These are sometimes called "inverters"

This is the Pressure Control Drive = PCZ

It gets a signal from the PRC and drives the motor with the % of full power as specified by the PRC

This is the blower motor.  It is a 3-phase, 230 volt AC motor. It is 1/2 horsepower.

This is the Temperature Transmitter = TT

The TT is a Solid state integrated circuit transducer, it is known as an LM-35.  It sends a signal voltage out that is proportional to the temperature in the duct.

This is one of two dampers. They close off one or two of the three arms of the pressure system that the blower supplies.  To see a movie of the damper operating, click below.
