The Boost Heat Option increases
the Zoneline air temperature by
adding electric heat to supplement
the heat pump. It automatically
turns on when the outside tempera-
ture is between 25 F. and 45 F.
To set the Boost Heat Option, move
switch 8 to the ON (up) position.
The Electric Heat Option increases
the Zoneline air temperature by
using electric heat only. The heat
pump is not used to produce any
heat.
If you want warmer air from the
Zoneline, and the Boost Heat
Option is not warm enough, this
option will provide the hottest air
available.
If the Zoneline is controlled by
a wall thermostat, the Boost Heat
Option provides ALL the heat
when the outside temperature is
below 45 F.
The Boost Heat Option is more
expensive than heating with the
heat pump only.
To set the Electric Heat Option,
move switch 7 to the ON (up)
position.
Using the Electric Heat Option is
much more expensive than heating
with the heat pump only.
