3. Convenience Outlet:
Outlet shall be factory-installed and internally mounted with easily accessible 115-v female receptacle. Outlet
shall include 15 amp GFI (ground fault interrupter) receptacle with independent fuse protection. Voltage required
to operate convenience outlet shall be provided by a factory-installed step-down transformer. Outlet shall be ac-
cessible from outside the unit.
4. Thermostat Controls:
a. Programmable multi-stage thermostat shall have 7-day clock, holiday scheduling, large backlit display, remote
sensor capability, and Title 24 compliance.
b. Commercial Electronic Thermostat shall have 7-day time clock, auto-changeover, multi-stage capability, and
large LCD (liquid crystal display) temperature display.
5. Louvered hail Guard Package:
Louvered hail guard package shall protect coils against damage from hail and other flying debris.
6. Condenser Coil Grille (Novation coil models 07--14):
Grille shall add decorative appearance to unit and protect condenser coil from large objects and vandalism.
