Boost Heat Option

To set the Boost Heat Option, move switch #8 to the UP (on) position.

Auxiliary controls
If the Zoneline is controlled by a wall thermostat and Boost switch #8 is set to the UP (on) position, only electric heat is available when the outdoor temperature is below 45° F.
The Boost Heat Option is more expensive than heating with the heat pump only.
Electric Heat Option
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.
To set the Electric Heat Option, move switch #7 to the UP (on) position.
