Figure 67. Damper actuator for mixing

section

Model Number Digit 31 = C or D

Damper actuator.

This damper actuator uses a 0–10 Vdc signal and is factory-wired and

mounted to the damper assembly. It allows zero to 100 percent fresh air.

The damper will drive open to an adjustable minimum stop-position

whenever the fan is running during occupied mode and will spring-return

closed when the fan turns off.

Trane recommends using the low temperature detection option with

fresh air dampers to detect possible freeze conditions.

Figure 68. Miscellaneous end devices

Optional end devices include (clockwise L-R): discharge air sensor (digit

31=A, B, C, D), duct static pressure transducer (digit 32=B), condensate

overflow switch (digit 30=1), and fan status switch (digit 30=1).
