The standard wall thermostat interface provides a
simple to install thermostat connection. The unit has
a removable terminal connector to make field wiring
easy. See more info on wall thermostat connections
in the Dimensional Drawings and Installation Data
Section.
Notes
:
— Thermostat wire is field supplied and
recommended wire size is 18 to 20 gage
solid thermostat wire.
— Wire should never be routed through the
wall sleeve.
— It is recommended to include extra wires
in case a wire breaks or is cut during
installation.
— The thermostat is ordered separately and
a Carrier PTAC approved thermostat is
recommended, see the accessory chart in
the back.
