Temperature Limit Switch Usage for Gas
Heat Units
Units are factory shipped in the downflow 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 either attached to the
combustion blower motor (6 to 12.5T) or to the installed
TCO1 limit switch (15 to 25T) if horizontal discharge
configuration is used.
If any of the units are installed in the downflow discharge
configuration and have the alternate TCO1 limit switch
provided, remove the additional TCO1 limit switch which is
either attached to the combustion blower motor (6 to 12.5T)
or to the installed TCO1 limit switch (15 to 25T) and
discard.
For detailed instructions, refer to
