signifies hazards that could result in personal injury or

death.

CAUTION

is used to identify unsafe practices which would result in

minor personal injury or product and property damage.

NOTE

is used to highlight suggestions which will result in enhanced

installation, reliability, or operation.

PERSONAL INJURY, DEATH AND / OR PROPERTY

DAMAGE HAZARD

Failure to follow this warning could result in personal injury,

death or property damage.
Improper

installation,

adjustment,

alteration,

service,

maintenance, or use can cause explosion, fire, electrical shock,

or other conditions which may cause personal injury or

HEATING AND COOLING YOUR HOME

Your geothermal system operation is controlled by the thermostat
which is generally mounted in a central location in the home.
A wide variety of thermostats can be used with your geothermal
unit. You can set the desired heating and cooling “set-points” on
your thermostat. The thermostat senses indoor temperatures and
sends a signal to the geothermal unit to heat, cool, turn off, or
change stages.
For enhanced comfort, consider setting your thermostat in
“constant fan” mode. This mode keeps the fan/blower operating
continuously which can provide more consistent temperatures
throughout the home, eliminating hot spots and cold spots.
Using the “auto change-over” mode on your thermostat will enable
the unit to automatically switch from heating to cooling (and
vice-versa) when necessary. This mode is beneficial, for example,
during the spring or fall when heating may be needed at night and
cooling may be needed during the day.

THERMOSTATS

A wide variety of thermostats can be used with your geothermal
unit. For thermostat operation instructions, refer to the thermostat
Owner’s Guide.

PROGRAMMABLE THERMOSTATS

If your thermostat is programmable, using the set-back feature can
provide additional energy savings. However, energy savings may
not be maximized if the heating set-back temperature is
substantially different from the normal temperature. For example,
if you want the “occupied” temperature to be 72ºF (22ºC), and you
program the thermostat for a set-back temperature of 60ºF (15ºC),
then the geothermal unit will likely engage the auxiliary back-up
heat when it is time for the normal temperature setting to be
achieved, in order to attain the programmed higher temperature in a
short period of time. The energy savings gained during the
set-back period may be lost if the unit has to operate with auxiliary
electric to bring the temperature back up to the normal setting.
Therefore, it is recommended to limit the difference between the
normal temperature setting and the set-back temperature during
heating to minimize the use of auxiliary electric.
