A trained, experienced
the technician must install this product. Carefully read these instructions. You could damage this product or cause a hazardous condition if you fail to follow these instructions.

Installation Tips

The thermostat should be installed approximately 4 to 5 feet above the floor. Select an area with average temperature and good air circulation.

Pick an installation location that is easy for the user to access. The temperature of the location should be representative of the building.

Subbase Installation

1. Horizontal Mount
2. Vertical Mount

For vertical mount put one screw on the top and one screw on the bottom. For horizontal mount put one screw on the left and one screw on the right.

Do not install thermostats in locations

• Chose to hot or cold air ducts
• That is in direct sunlight
• With an outside wall behind the thermostat
• In areas that do not require conditioning
• Where there are dead spots or drafts(in corners or behind doors) Where there might be concealed chimneys or pipes

Installation Tip:

Electrical Hazard
Failure to disconnect the power before beginning to install this product can cause electrical shock or equipment damage.

Mercury Notice
All of our products are mercury-free. However, if the product you are replacing contains mercury, dispose of it properly. Your local waste management authority can give you instructions on recycling and proper disposal.

Mount Thermostat
Align the 4 tabs on the subbase with corresponding slots on the back of the thermostat, then push gently until the thermostat snaps in place.

Battery Installation
Battery installation is recommended even if the thermostat is hardwired (C terminal connected). When the thermostat is hardwired and batteries are installed, the thermostat will activate a compressor delay of 5 minutes when the thermostat detects a power outage from the hardwired power supply.

Getting to know your thermostat

1. Indicates the current room temperature
2. Time and day of the week
3. Low Battery Indicator: Replace batteries when this indicator is shown.
4. Program Time Periods: This thermostat has 4 programmable time periods per day.
5. System Operation Indicators:
6. The COOL ON, and HEAT ON will display when COOL or HEAT is on.
   Note: The Compressor delay feature is active if these are flashing.
7. The hold is displayed when the thermostat program is permanently overridden.
8. Setpoint: Displays the user-selectable setpoint temperature.
9. Stages: Indicates the stages of heat that are active.

Important
The low battery icon is displayed when the AA battery power is low. Whenever the thermostat detects low battery voltage from the AA batteries, the low battery icon will begin flashing on the screen for 21 days (if the batteries are not changed). If the batteries are not changed 22 days after the thermostat detects low battery voltage, the thermostat screen will only show the flashing battery icon until the buttons are pressed. If the batteries are not changed 43 days after the thermostat detects low battery voltage, the thermostat screen will only show the flashing battery icon until buttons are pressed and the set points will offset to 85°F/29°C in cooling and 55°F/13°C in heating. At this stage, set point changes can be made temporarily but, the set points will change back to defaulted values after a 4-hour period. The thermostat will continue to perform this low battery flashing, temperature offset condition until the internal voltage threshold is reached. When the thermostat internal voltage threshold is reached, all relays will be opened and the thermostat will become inoperable until new batteries are installed.

Wiring

Caution: Electrical Hazard Failure to disconnect the power before beginning to install this product can cause electrical shock or equipment damage.

1. If you are replacing a thermostat, make note of the terminal connections on the thermostat that is being replaced. In some cases, the wiring connections will not be color coded. For example, the green wire may not be connected to the G terminal.
2. Loosen the terminal block screws. Insert wires then retighten terminal block screws.
3. Place non-flammable insulation into the wall opening to prevent drafts. All components of the control system and the thermostat installation must conform to Class II circuits per the NEC Code. Do not overtighten terminal block screws, as this can damage the terminal block. A damaged terminal block can keep the thermostat from fitting on the sub base correctly or cause system operation issues.

Tech Settings

This thermostat has a technician setup menu for easy installer configuration. To set up the thermostat for your particular application:

The Technician Setup Menu

1. To enter all other steps press and hold and buttons together for 3 seconds. This 3-second delay is designed so that homeowners do not accidentally access the installer settings.
2. Use buttons to set.
3. Press the Program button to advance to the next step.
4. Press the time button to go back to the previous stop.
5. Press the Hold/Run button to exit.

Swing Setting Tip
The temperature swing, sometimes called differential or cycle rate, can be customized for this individual application. For most applications choose a swing set that is as long as possible without making the occupants uncomfortable

Room Temperature Calibration	This feature allows the installer to change the calibration of the room temperature display. For example, if the thermostat reads 70˚ degrees and you would like it to read 72˚ then select +2.	CAL 0	You can adjust the room temperature display to read 4˚above or below the factory calibrated reading.	0
Compressor Short Cycle Delay	The compressor short cycle delay protects the compressor from short cycling. This feature will not allow the compressor to be turned on for 5 minutes after it was last turned off.	Cd	Selecting “ON” will not allow the compressor to be turned on for 5 minutes after the last time the compressor was switched off. Select “OFF” to remove this delay.	0N

Swing Setting Tip
The temperature swing, sometimes called differential or cycle rate, can be customized for this individual application. For most applications choose a swing set that is as long as possible without making the occupants uncomfortable.

F or C	Select F for Fahenheit temperature read out or select C for Celsius read out.	FC F	F for Fahrenheit C for Celsius	F
Dual Fuel	For Dual Fuel applications (Gas/ Fossil fuel Auxiliary Heat), turn this setting ON to LOCKOUT the Heat Pump (Y) when Auxiliary Heat (W2) is on. If desired- This can also be used with Electric Auxiliary.		OFF Will allow Y(1st stage of Heat) and W2 (Aux Heat) to run together if called for. ON Will de-energize Y terminal 45 seconds after a call for Auxiliary Heat (W2).	OFF
Auxiliary

Cooling Swing	The swing setting often called “cycle rate”, “differential” or “ anticipation” is adjustable. A smaller swing setting will cause more frequent cycles and a larger swing setting will cause fewer cycles.		The cooling swing setting is adjustable from 0.2˚ to 2˚. For example: A swing setting of 0.5˚ will turn the cooling on at approximately 0.5˚ above the setpoint and turn the cooling off at approximately 0.5˚ below the setpoint.	0.8
Heating Swing	The swing setting often called “cycle rate”, “differential” or “anticipation” is adjustable. A smaller swing setting will cause more frequent cycles and a larger swing setting will cause fewer cycles.	HE	The heating swing setting is adjustable from 0.2˚ to 2˚. For example: A swing setting of 0.5˚ will turn the heating on at approximately 0.5˚ below the setpoint and turn the heating off at approximately 0.5˚ above the setpoint.	0.8
Cooling Setpoint Limit	This feature allows you to set a minimum cool setpoint value. The setpoint temperature cannot be lowered below this value.	44 CL	Use the    and      key to select the minimum cool setpoint.	44
Heating Setpoint Limit	This feature allows you to set a maximum heat setpoint value. The setpoint temperature cannot be raised above this value.	90 HL	Use the    and      key to select the maximum heat setpoint.	90
