If your heat pump has Energy Monitoring installed, the screen shall be this:

If the FAN hasn’t been on for an hour, the fan will start cycling based on these times. Default is OFF. The first screen is the amount of time you want the fan to be energized. Ranges are

OFF to 20 minutes in 5 minute increments. Then adjust the time of the fan is OFF. Ranges are 5-40 minutes in 5 minute increments. Fan ON and OFF cycles will continue until the fan has been energized by a call for heating or cooling.

Humidity

(NOTE: This option is not available if configured as a Zone

Thermostat, but is available at the MasterStat)

NOTE: The humidity function must be enabled by the installer for it to display on this screen. If your system does not use a humidifier this function may not be enabled.

(If configured as a Zone Thermostat, the menu will appear as depicted below.)

Fan Operation

The thermostat can operate the fan in three ways:

AUTO (on only during heating and cooling calls)

CONTINUOUS (always on)

INTERMITTENT (cycles fan)

1. From the Home screen or Menu, press the Fan button.

2. Select the operation you desire as described above by pressing the up and down arrows ▲▼.

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.

The humidity function must be enabled by the installer for this screen to be visible. If your system does not use a humidifier then this option may not be enabled. This allows adjustment of

Humidification and Dehumidification settings. Options are Auto,

Manual, factory default setting for Dehumidification is “Auto”.

Humidification “Auto” is only available if an outdoor sensor is installed. Humidification only works with an active heating call. Manual humidity choices range from 15% to 50% in 1% increments. Dehumidification choices range from 35% to 65% in 1% increments.

Active dehumidification

(Variable Speed Heat Pumps Only)

This feature will only activate during cooling operation and is based upon the humidity set point of the thermostat being at least 5% below the actual relative humidity. When in active dehumidification the room temperature could be overcooled 1.5°F below set point.

In this mode you may see increased energy usage due to the additional compressor run time.

Display Dealer Information

The installing dealer’s contact information can be displayed on this screen. From the main screen, press Menu and then press

Dealer. Simply press the screen segment where information is to be entered and a keypad will appear.

Installer Information/Advanced Features

Safety Considerations

Improper wiring or installation may damage thermostat. Wiring must conform to local and national electrical codes.

Introduction

The thermostat is a wall mounted, low-voltage thermostat which 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

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:

• Remove existing thermostat from wall.

• Disconnect wires from existing thermostat, one at a time.

Be careful not to allow wires to fall back into the wall.

• As each wire is disconnected, record wire color and terminal marking.

• 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.

7. Connect wires to proper terminal of the connector block in the front plastic.

8. Push any excess wire back into wall. 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 operation.

9. Snap front and back pieces of plastic together.

10. Turn on power to the unit.

CAUTION: To clean the thermostat display, lightly dampen a clean non-abrasive cloth with water or any non-abrasive household cleaner. To clean, gently wipe the surface of the thermostat.

NOTE: Do not spray liquids directly on the

Smart Recovery

(NOTE: This option is not available if configured as a Zone

Thermostat.)

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.
