Temperature Limit Switch Usage For Gas Heat Units - Trane YHC092E Installation, Operation And Maintenance Manual

Temperature Limit Switch Usage for Gas
Heat Units
Units are factory shipped in the down flow discharge
configuration but can be field converted to a horizontal
discharge configuration. Some, but not all units require a
different TCO1 limit switch, which is attached to the
combustion blower motor if horizontal discharge
configuration is used.
Note: The following units require a limit switch change
out for horizontal discharge. The additional limit
switch is shipped attached to the combustion
blower housing: YSC036E**(M,Y),
YSC036E**(H,Z), YSC048E**(H,Z),
YSC048E**(M,Y) belt drive ID motor,
YSC060E**(H,Z) direct drive ID motor,
YHC047E**(L,X), YHC048E/F**(L,X) direct drive ID
motor, YHC060E/F**(L,X) belt drive ID,
