Offsets
1. MENU → SETTINGS → OFFSETS
Temperature Offsets
This option allows calibration (or deliberate
miscalibration) of the room temperature sensor(s). There
are various reasons why the displayed temperature
would be adjusted to a higher or lower value. NOTE: Do
not adjust for 30 minutes after installation because board
may be heated by handling. The selected number is the
number of degrees, plus or minus, which will be added to
actual temperature. The numbers can range between -5˚
and +5˚. Default values are set to 0˚ offset.
Temperature Offset
Remote Indoor Offset (if sensor is attached)
Outdoor Offset (if sensor is attached)
Humidity Offset
This option allows calibration of the humidity sensor.
Adjustments can range between -10% and +10%. Default
is 0% offset.
Auto Changeover
With auto changeover, the thermostat automatically switches itself
from heating to cooling, or vise versa, based on the setpoints.
When setting up the thermostat you have to enter both a cooling
setpoint and a heating setpoint. The thermostat will also prevent
the user from setting the cooling setpoint lower than the heating
setpoint. Mode is set to AUTO for this operation to work.
MENU → SETTINGS → AUTO CHANGEOVER
Auto Changeover Time – This setting sets the minimum off time
before the thermostat can change from one mode to
another. Default is 5 minutes. Range is from 0-120
minutes in 15 minute increments.
Auto or Manual Change – Default is AUTO. If MANUAL is
chosen, you will need to change from heating to
cooling or vise versa. When MANUAL is set, AUTO is
removed from the MODE screen as a choice.
Instantaneous Energy Monitoring
Instantaneous Energy Monitoring
can be found under the main menu,
if the energy monitoring option has
been enabled on the Aurora Control
System. The screen displays energy
usage in real time, the current mode
of the heat pump, and the outdoor air
temperature (if installed).
Superboost (Variable Speed Heat Pumps ONLY)
Superboost can be found under the main menu. The Superboost
option temporarily enables a larger cooling capacity range. The
screen will allow the homeowner to turn on or off the Superboost
option. The option will enable by default for a 24 hour period of
time and then will automatically be disabled.
WARNING: OVERUSE OF THIS OPTION MAY
CAUSE OVERHEATING OF LOOPS.
Intermittent Fan
Temperature conditions can vary widely between the thermostat
location and extremities of the space the thermostat serves.
This air stratification problem can be especially pronounced
during mild outdoor conditions when long periods elapse
between space conditioning demands from the thermostat. This
intermittent fan operation can also improve the performance of
air cleaning or special filtration systems that locate the cleaning
or filtration media at the return air side of the fan.

Thermostat Location
Thermostat should be mounted:
- Approximately 5 ft. (1.5m) from floor.
- Close to or in a frequently used room, preferably on an
inside partitioning wall.
- On a section of wall without pipes or duct work.
Thermostat should NOT be mounted:
- Close to a window, on an outside wall, or next to a door
leading to the outside.
- Exposed to direct light and heat from a lamp, sun,
fireplace, or other temperature-radiating object which
may cause a false reading.
- Close to or in direct airflow from supply registers and
return-air grilles.
- In areas with poor air circulation, such as behind a door
or in an alcove.
Install Thermostat
1. Turn off all power to unit.
2. If an existing thermostat is being replaced:
a) Remove existing thermostat from wall.
b) Disconnect wires from existing thermostat, one at a
time. Be careful not to allow wires to fall back into the

c) As each wire is disconnected, record wire color and
terminal marking.
d) Discard or recycle old thermostat.
NOTE: Mercury is a hazardous waste and MUST be
disposed of properly.
3. Separate the front and back pieces of plastic.
4. Route thermostat wires through hole in back piece of
plastic. Level plastic against wall (for aesthetic value only
- thermostat need not be leveled for proper operation) and
mark wall through 2 mounting holes.
5. Drill two 3/16-in. mounting holes in wall where marked.
(NOTE: Mounting holes on thermostat are designed to fit
on a horizontal J-box).
6. Secure back plastic to wall with 2 anchors and screws
provided making sure all wires extend through hole in plastic.

Smart Recovery
Smart recovery is a feature of your thermostat designed to
improve comfort by adjusting temperatures to achieve a room
temperature by the programmed time. When it’s time for a
programmed temperature change, smart recovery begins working
in advance, turning the system on and off as needed to adjust
the indoor temperature. During these transition periods, you
may notice that the actual temperature and your temperature
setting don’t match. That’s smart recovery in action, adjusting
temperatures in small increments for greater energy efficiency.
This is more energy efficient than simply allowing the system to
operate at full capacity until the desired temperature has been
met. Smart Recovery helps avoid excessive use of auxiliary heat
when recovering from night setback in the heating mode.
