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:
2. Do not adjust for 30 minutes after installation because the board may be heated by handling. The selected number is the number of degrees, plus or minus, which will be added to the actual temperature. The numbers can range between -5˚ and +5˚. Default values are set to 0˚ offset. Temperature Offset
3. Remote Indoor Offset (if the sensor is attached) Outdoor Offset (if the sensor is attached)

Humidity Offset
This option allows the calibration of the humidity sensor. Adjustments can range between -10% and +10%. The default is 0% offset.

Auto Changeover
With the auto changeover, the thermostat automatically switches itself from heating to cooling, or vice 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. The mode is set to AUTO for this operation to work.MENU → SETTINGS → AUTO CHANGEOVER Time – This setting sets the minimum off time before the thermostat can change from one mode to another. The default is 5 minutes. The 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.

1. MENU → SETTINGS → INTERMITTENT FAN
2. If the FAN hasn’t been on for an hour, the fan will start cycling based on these times. The default is OFF. The first screen is the amount of time you want the fan to be energized. Ranges are OFF, or 5-20 minutes in 5-minute increments.
3. After entering this time and pressing the center button ■, the next screen is the amount of time the fan is OFF. Ranges are 0 minutes or 5-40 minutes in 5-minute increments.
4. After entering this time and pressing the center button ■ you will be returned to the Setting Menu screen.
5. Fan ON and OFF cycles will continue until the fan has been energized by a call for heating or cooling.

Service Information
MENU → SETTINGS → SERVICE INFO These screens help an installer or contractor to have a good understanding of what problems might be occurring before arriving for service.

WARNING: Before installing the thermostat, turn off all power to the unit. There may be more than one power disconnect. Electrical shock can cause personal injury or death.

Installer Information/Advanced Features
Safety Considerations
Improper wiring or installation may damage a thermostat. Wiring must conform to local and national electrical codes

Introduction
The thermostat is a wall-mounted, low-voltage thermostat that maintains room temperature by controlling the operation of a heating and air conditioning system. Batteries are not required; temperature and mode settings are preserved with the power off.

Installation Considerations
The thermostat requires no batteries. The thermostat is not a power-stealing device and MUST have both R and C connected.

Installation

Thermostat Location
The thermostat should be mounted:

• Approximately 5 ft. (1.5m) from the floor.
• Close to or in a frequently used room, preferably on an inside partitioning wall.
• On a section of the wall without pipes or ductwork.

The 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 another 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 the unit.
2. If an existing thermostat is being replaced:
   • Remove the existing thermostat from the wall.
   • Disconnect wires from the existing thermostat, one at a time. Be careful not to allow wires to fall back into the wall.
   • As each wire is disconnected, record the wire color and terminal marking.
   • Discard or recycle old thermostats.
     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 holes 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 the wall where marked.
   (NOTE: Mounting holes on the 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 the plastic.
7. Connect wires to proper terminal of the connector block in the front plastic.
8. Push any excess wire back into wall. The excess wire inside the thermostat plastic case can interfere with proper air flow across the temperature sensor. Seal hole in wall to prevent air leaks. Leaks can affect operations.
9. Snap front and back pieces of plastic together.
10. Turn on power to the unit.

Wiring Diagrams

All excess wire should be pushed back into the wall as far as possible. Excess wire inside the thermostat plastic case may interfere with the air flow across the temperature sensor. Thermostat Connections

Installer Settings
NOTE: These options are intended to be used by the installer. End users are not advised to change or modify any of these settings. Doing so may make your equipment stop working properly and/or may void the warranty of the thermostat as well as the equipment hooked up to the thermostat. To access the installer setting menu, the mode must be set to OFF. Then, press both the up and down arrow keys at the same time for at least 5 seconds to enter the installer screen.

Model Configuration
Options to select from
PROGRAMMABLE / NONPROGRAMMABLE, SINGLE-STAGE/MULTI STAGE

• Single Stage – Used with heat pumps with PSC motors
• Multi-Stage – Used with heat pumps with ECM motors, either Single Speed or Dual Capacity

NORMAL/DUAL FUEL/INTELLIGENCE STANDARD/ INTELLIGENCE NO DOWN STAGING Normal – used for normal operation
Dual Fuel – used on dual fuel systems. Needs an outdoor sensor to lockout dual fuel. IntelliZone Standard – used with IntelliZone. The ‘W’ acts like a Y3 and requires less droop. It activates 3rd stage with the same time/temperature weighting as Y1 and Y2. IntelliZone No Down Staging – used with IntelliZone and if used, SHOULD BE ONLY ON MAIN ZONE. The thermostat will hold the deepest call encountered and should minimize compressor speed changes.

Dehumidify – Turns on the DH output when the room humidity is above the set point and the MODE is set to COOL or AUTO when Cool was the last mode run.
Both – HUMIDIFY operates in the HEAT mode and
DEHUMIDIFY operates in COOL mode.
None – Neither is active.

Reversing Valve Option
Option of the reversing valve (O output) being on when in cooling or heating. The default is COOLING.

Restore Defaults
This will allow you to revert to the factory default settings.

Anticipator
This adjustment controls the sensitivity and cycle rate of the thermostat. Higher numbers decrease the cycle rate. Lower numbers increase the cycle rate. The default value is 0, and the range is 0-4.

Differential
This adjustment will vary the number of degrees, from the set point, before a call for heating or cooling is made. Adjustments can range between 0.5˚ and 4˚ differential. The default is 0.5˚ offset. (If your set point is 70˚F in heating, your thermostat will not call for heat until the temperature is 69.5˚F, with a 0.5 differential).

Cycles Per Hour
This feature will not allow more than the specified number of equipment cycles per hour. Values can range from 4 or 6 (or 1 cycle every 15 minutes (default) or 1 cycle every 10 minutes, if 6 is set).

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 a 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 setbacks in the heating mode.

Events Per Day
This is where you can set the number of events per day. (An event is a period of time scheduled with a certain heating and cooling setpoint.) For instance, if you are away from your home from 8am to 5pm, make this period of time an event and set the thermostat at an energy-saving setting. You have the option of setting the events per day to 4-RESIDENTIAL (4 events), 2-RESIDENTIAL (2 events) or 2-BUSINESS (2 events).

Smart Heat Staging (Heat Pump Only)

This delays 3rd stage heating for a set time. Options are ON or OFF. The default is OFF. The range for this are 0-120 minutes in 5-minute increments. If set to ON, 30 minutes is the default time.( If ‘ON’ is selected and the demand has not been satisfied the thermostat will energize electric heat after the selected time has expired regardless of demand.)

Cooling Lockout
When an outdoor temperature sensor is installed, it can be set up so the cooling option doesn’t energize if the outdoor temperature is below a certain temperature. Ranges for this are NONE
(default), 45˚F, 50˚F, or 55˚F.

Electric Heat Or Dual Fuel Lockout
When an outdoor temperature sensor is installed, you can set it up so the electric heat or Dual Fuel option doesn’t energize if the outdoor temperature is above a certain temperature. Ranges for this are NONE (default), 5˚F to 60˚F in 5˚ increments.

Compressor Satisfy
Normal – Allows compressor downstaging from Y2 to Y1. Recommended setting for most products. Y2 Finish – Once the heat pump has engaged Y2 the thermostat will not allow downstaging to Y1. The call is satisfied in Y2.

Remote Sensor
Allows selection of the remote sensor to determine indoor temperature. Options are REMOTE SENSOR, AVERAGE, and STAND ALONE. The REMOTE SENSOR is connected to the ID and GND on the thermostat terminals.

Faults

Non-Critical Faults
Non-critical faults are displayed below the temperature on the main screen. These faults will clear themselves if the fault condition corrects itself. Your dealer should be informed when either a critical or non-critical fault occurs.
Lockout/Critical Faults
Critical faults will change the screen to the service needed screen and turn the backlight color to red. The system can be reset by pressing the left arrow key on the thermostat. Some of the faults will clear themselves if the fault condition corrects itself. Your dealer should be informed when either a critical or non-critical fault occurs.
