Factory Installed Options

 Cupro-nickel Coil:

— Recommended in conditions anticipating moderate

scale formation or in brackish water.

 Internal Electric Heat:

— Can be factory mounted or field installed. Choices

include 5, 10, 15, or 20 kilowatt back up or an emergency heater depending on the size of the

geothermal heat pump.

 Domestic Hot Water Heat Recovery Package:

— Used to heat domestic hot water using the wasted heat

from the hot compressed gas of the compressor.

 Dehumidification:

— Lower the humidity in your home allowing you to turn

up the thermostat in the summer.

 SmartStart:

— A factory installed start up device that improved start

up effieciency as much as 65% and helps reduce wear and tear on the compressor during start up.

Field Installed Accessories

 Thermostats:

— Bosch thermostats are fully customized to meet your

individual needs. True Communicating thermostat that displays the alert messages without having to go to the unit.

 DDC Control:

— Field Conversion Kit
