General
Data
What you should know about this designation...
1 Opposite-end coil piping connections are provided when selecting the 4-pipe or coupled coil option.
Same-side coil connections are not provided from Trane.
2 If a cooling coil is selected in DIGIT 12, the drain pan slopes toward the cooling coils piping connection.
TUC and ZN520 Controls
1 If DDC (TUC or ZN520) controls are selected, the coil control valves and actuators must be ordered from
the factory. This is to ensure that the system hardware is capable of working intimately with the con-
troller to allow the system to function properly.
2 Fan and filter status is available when selecting the Integrated Comfort System ONLY. Standalone con-
trols do not contain a device for status report for this option.
3 All internal sensors are provided in the unit if factory mounted DDC controls are selected.
Pneumatic Controls
1 Pneumatic controls are available with face and bypass coil control with exception of 4-pipe and steam
coil selections. This is due to the need for isolation valve control for the coils
on a pneumatic system.
2 Because the pneumatic package is factory calibrated from Johnson Controls
possible.
End Device Controls
1 The end device control package is available with factory wired valves, actuators and freeze-stat (but
not required). A 24-volt transformer and a start/stop relay is provided with this control option.
2 Face and bypass is not a selectable option with the end device package because of terminal strip wiring
limitations.
3 Trane zone sensors will not be provided with this control option.
4 DX, electric heat, and steam coils will not be allowed when selecting end device controls.
5 Crossover piping is not allowed when selecting end device controls.
1 The face and bypass selection (Digit 16 = 2,3,4,5,7) is allowed with the TUC and ZN520 controls ONLY.
All E, F, X, R and DK-style coils are not available with the face and bypass selection.
2 Isolation valves may be factory piped or shipped loose to the job site. They are of open or closed op-
eration ONLY. Modulating valves are not available. The valves spring return to their "normal" or non-
energized state (either normally open for heating, or normally closed for cooling).
3 Valve control for pneumatic controls is provided when Digit 16 = D,E,F,M,N,P. The valves may be fac-
tory piped, or shipped loose.
4 Valve control for TUC, ZN520 and end device controls is provided when Digit 16 = 8,9,W,G,H,X,Y,Z,Q,R.
The valves may be factory piped, or shipped loose.
5 Valve control for steam coils are provided when Digit 16 = T,U,V. These valves are shipped loose ONLY,
and are used with TUC, ZN520, end device and pneumatic controls.
1 Single stage DX control (Digit 17 = 1) is allowed with the TUC and ZN520 controls ONLY.
2 Isolation valves may be factory piped or shipped loose to the job site. They are of open or closed op-
eration ONLY. Modulating valves are not available. The valves spring return to their "normal" or non-
energized state (either normally open for heating, or normally closed for cooling).
3 Valve control for pneumatic controls is provided when Digit 17 = D,E,F,M,N,P. The valves may be fac-
tory piped, or shipped loose.
4 Valve control for TUC, ZN520 and end device controls is provided when Digit 17 = W,G,H,Z,Q,R. The
valves may be factory piped, or shipped loose.
device controls.
2 2-position damper control (Digit 18 = B,C) is only available when selecting TUC or ZN520 controls.
3 The manual quadrant adjust damper control (Digit 18 = D) remains in a fixed position. The unit must
be physically opened, and manually adjusted to a new position.
