A quick reference to controls

A quick reference to the display screen

Set the time and day

1. Press the SET CLOCK/DAY/SCHEDULE button, then press to set the clock time.
2. Press the SET DAY button, then press to select the day of the week.
3. Press DONE to save & exit.
   Note: If the SET CLOCK/DAY/SCHEDULE option is not displayed, press DONE or RUN SCHEDULE.
   Note: If the display flashes Set Clock, the thermostat will follow your settings for the weekday “Wake” time period until you reset the time and day.

Select the fan setting

Press the FAN button to select Auto or On.
In “Auto” mode (the most commonly used setting), the fan runs only when the heating or cooling system is on. If set to “On,” the fan runs continuously. Use this setting for improved air circulation, or for more efficient air cleaning.

Select the system setting

Press the SYSTEM button to select:

• Heat: Controls only the heating system.
• Cool: Controls only the cooling system.
• Off: Heating and cooling systems are off.
• Auto: Automatically selects heating or cooling depending on the indoor temperature.
• Em Heat (only for heat pumps with auxiliary heat): Controls Emergency Heat.
  The compressor is locked out.

Note: The Auto and Em Heat system settings may not appear, depending on how your Comfort Control was installed.

Save money by setting program schedules

It’s easy to program your system for maximum energy savings. You can program four time periods each day, with different settings for weekdays and weekends.

• Set to the time you awaken and the temperature you want during the morning, until you leave for the day.
• Set to the time you leave home and the temperature you want while you are away (usually an energy-saving level).
• Set to the time you return home and the temperature you want during the evening, until bedtime.
• Set to the time you go to bed and the temperature you want overnight (usually an energy-saving level).

EnergyStar® settings for maximum cost savings

This Comfort Control is pre-set to use EnergyStar® program settings. We recommend these settings since they can reduce your heating/cooling expenses by as much as 33%. (See next page to adjust times and temperatures of each time period.)

Program schedules

To adjust program schedules

1. Press SET CLOCK/DAY/SCHEDULE, then SET SCHEDULE.
2. Press to set your weekday Wake time (Mon–Fri), then press NEXT.
3. Press to set the temperature for this time period, then press NEXT.
4. Set time and temperature for the next time period (Leave). Repeat steps 2 and 3 for each weekday time period.
5. Press NEXT to set weekend time periods (Sat-Sun), then press DONE to save & exit.
   Note: Make sure the Comfort Control is set to the system you want to program (Heat or Cool).
   Note: You can press CANCEL PERIOD to eliminate unwanted time periods (except Wake).

Program schedule override (temporary)

Press to cancel temporary setting and resume program schedule.
Note: Make sure the Comfort Control is set to the system you want to control (heat, cool, or auto).

Press to immediately adjust the temperature. This will temporarily override the temperature setting for the current time period.
The new temperature will be maintained only until the next programmed time period begins. For example, if you want to turn up the heat early in the morning, it will automatically be lowered later, when you leave for the day.
To cancel the temporary setting at any time, press RUN SCHEDULE.

Auto Changeover (heat/cool)

Auto Changeover is a feature used in climates where both air conditioning and heating are used on the same day. When the system is set to Auto, the Comfort Control automatically selects heating or cooling depending on the indoor temperature.
Heat and cool settings must be at least 3 degrees apart. The Comfort Control will automatically adjust settings to maintain this
3-degree separation (called “deadband”).
The 3-degree separation between heating and cooling set temperatures is fixed, and cannot be changed.

Built-in compressor protection

This feature helps prevent damage to the compressor in your air conditioning or heat pump system.
Damage can occur if the compressor is restarted too soon after shutdown. This feature forces the compressor to wait for a few minutes before restarting.
During the wait time, the display will flash the message Cool On (or Heat On if you have a heat pump). When the safe wait time has elapsed, the message stops flashing and the compressor turns on.

Adaptive Intelligent Recovery (AIR)

Adaptive Intelligent Recovery eliminates guesswork when setting your schedule.
It allows Comfort Control to “learn” how long your furnace and air conditioner take to reach the temperature you want.
Just set your program schedule to the time you want the house to reach your desired temperature. The Comfort Control then turns on the heating or cooling at just the right time to reach your scheduled temperature at your scheduled time.
For example: Set the Wake time to 6 am and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6.

Note: When Adaptive Intelligent Recovery is in effect, the thermostat will display “In Recovery”.

Battery Replacement

Batteries are optional (to provide backup power) if your Comfort Control was wired to run on AC power when installed.
Install fresh batteries immediately when the REPLACE BATTERY warning begins flashing. The warning flashes about two months before the batteries are depleted.
Even if the warning does not appear, you should replace batteries once a year, or before leaving home for more than a month.
If batteries are inserted within two minutes, the time and day will not have to be reset. All other settings are permanently stored in memory and do not require battery power.

If you have difficulty with your thermostat, please try the following suggestions.
Most problems can be corrected quickly and easily.

Limited Warranty Low Voltage Room Comfort Controls (Parts Only)
This limited warranty is extended by the manufacturer to the original purchaser and to any succeeding owner of the real property to which the low voltage room comfort control is originally affixed and applies to products purchased and retained for use within the U.S.A. and Canada.
The limited warranty period begins when the low voltage room comfort control installation is complete, verified by the installer’s invoice or similar document. If installation completion and start-up date cannot be verified by installer’s invoice or similar document, limited warranty coverage begins six (6) months after the date of manufacture based on the low voltage room comfort control serial number.
If any part of your low voltage room comfort control fails because of a manufacturing defect within five (5) years from the date the limited warranty period begins, Warrantor will furnish without charge a new low voltage room comfort control. Any local transportation, related service labor, and diagnosis calls are not included.
This limited warranty does not apply if the low voltage room comfort control was purchased direct (i.e. from internet websites or auctions) on an uninstalled basis. Additionally, this limited warranty will not apply unless the low-voltage room comfort control is:

1. installed by a licensed or qualified HVAC technician,
2. applied and installed in accordance with the manufacturer’s recommendations in its Installer’s Guide, and
3. in compliance with all industry standards, and national, state, and local codes.

This limited warranty does not cover your low voltage room comfort control if it is damaged while in your possession; including, but not limited to

1. damage caused by unreasonable use of the low voltage room comfort control,
2. damage from failure to properly maintain the low voltage room comfort control as set forth in the Use and Care manual,
3. damage that is not considered a manufacturing defect, such as acts of God, malfunctions or failures resulting from fire, water, storms, lightning, earthquake, theft, riot, misuse, abuse, increased utility usage costs, or
4. performance problems due to improper selection/equipment match-up, installation, or application.

THE LIMITED WARRANTY AND LIABILITY SET FORTH HEREIN ARE IN LIEU OF ALL OTHER WARRANTIES AND LIABILITIES, WHETHER IN CONTRACT OR IN NEGLIGENCE, EXPRESSED OR IMPLIED, IN LAW OF IN FACT, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR PARTICULAR USE, AND IN NO EVENT SHALL WARRANTOR BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES.

Some states do not allow limitations on how long an implied limited warranty lasts or do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.
