This two-part wireless thermostat system is designed to provide precision temperature control without the installation headaches and expense of wiring. Powered by four AA batteries, the thermostat will operate for approximately 1 year, and can be mounted in any suitable location that will ensure good temperature control. A large LCD display provides the user with current space temperature, set point temperature, time, program interval and other system status information. The second part of the system is the receiver. The receiver interfaces with the desired HVAC equipment and communicates with its thermostat using unlicensed 900MHz radio frequency energy. At the time of installation, the thermostat is linked to one or more receivers. A thermostat and receiver that have been linked will not interfere with or be affected by any other thermostat or receiver in adjacent rooms, apartments or neighboring homes. Batteries. Installing/Changing A low battery icon will light on the thermostat display when the batteries are within a week or two of being exhausted. The thermostat is designed to use standard AA-size 1.5 volt batteries. If the batteries are depleted, the heating/cooling system will go to the OFF state. Replacing Batteries To open the thermostat, remove the security screw
(#2 Phillips or #2 security screw). Using both hands, press the two push-tabs on the bottom of the thermostat housing with your thumbs, while pulling the front of the thermostat away from the base. Thermostat cover Base plate Latches The thermostat operates with 4 AA batteries. Batteries are paired, one set on top of the other. Thermostat opened back 4 Thermostat will operate on either Set A, Set B or both. When changing, replace with all new batteries. Never use a mix of old and new. Battery orientation is critical.

Step Four Press the CLOCK button to keep all clock changes you have made and resume normal operation. 6 49-7574 v06 6/7/07 9:44 AM Page 7 Thermostat programming. The thermostat provides four program periods: Morning, Day, Evening and Night. A time and temperature can be set for each period. Upon initial power up, the thermostat loads time and temperature program default parameters for weekday and weekend days of the week. Default settings are:
WEEKDAY DEFAULT PROGRAM TIMES AND TEMPERATURES Period MORNING DAY EVENING NIGHT Time 6:00 AM 8:00 AM 6:00 PM 10:00 PM Heat 70 62 70 62 Cool 75 83 75 78 WEEKEND DEFAULT PROGRAM TIMES AND TEMPERATURES Period MORNING DAY EVENING NIGHT Time 8:00 AM 10:00 AM 6:00 PM 11:00 PM Heat 70 62 70 62 Cool 75 83 75 78 Separate heating and cooling programs can be entered. The mode the thermostat is in is displayed in the upper right side of the LCD screen. The mode the thermostat is in when the PROGRAM button is pressed is the mode that will be controlled by that program. If in the COOL mode, the program entered will be stored as the program for cooling. To program the thermostat, you will use the PROGRAM, HEAT/COOL, UP and DOWN buttons. 7 49-7574 v06 6/7/07 9:44 AM Page 8 Thermostat programming (cont.). Step One Press the PROGRAM button to put the thermostat into the programming mode. The display will blink all of the day-of-the-week icons. Pressing the UP or DOWN button will toggle between the weekday icons and the weekend icons. Ensure the display is blinking the one you want to program. Press HEAT/COOL. Step Two Next, the morning period will blink. Use the UP or DOWN button to toggle through Morning, Day, Evening or Night, stopping at the period you want to program. Press HEAT/COOL. Step Three Next, the hour of the day will blink. This is the starting hour of the period you have selected. Use the UP or DOWN button to change the selected hour start time. Press HEAT/COOL. Step Four The minute of the day will blink next. This is the starting minute in the hour. Use the UP or DOWN button to change the minute digits to the desired setting. (Note that minutes change in five-minute increments.) Press HEAT/COOL. Step Five The desired set point will now be blinking. This is the temperature you want the thermostat to go to at the time of day you have selected. Press the UP or DOWN button to change to the desired set point temperature. Press HEAT/COOL. This completes the programming of the first period of the day. Step Six If you started with the Morning time period, the next period, Day, will now be blinking. Follow steps two, three, four and five for each period you wish to program. 8 49-7574 v06 6/7/07 9:44 AM Page 9 Navigating. You can quickly step through to a specific item you want to change by pressing the HEAT/COOL button until the item you want to change is flashing. When the item you want to change is flashing, use the UP or DOWN button to make your change. Exiting program mode. Pressing the PROGRAM button at any time will exit you out of the programming mode, save your changes to memory and return you to normal thermostat operation. Run button program/manual operation. Th O Day HEAT Fan Auto 11:20 AM The RUN button toggles the thermostat between program operating mode and manual operating mode. When in the program mode, your thermostat responds to the times and temperatures programmed. Program Mode One of the four periods, in this case Day, is displayed, letting you know which period of the day it is in. Changing temperature while running a program. You can always change the temperature up or down while a program is running. However, when the program moves to the next period, the programmed set point temperature for that period will start. For instance, assume the current program peri-
od is Evening, with a programmed temperature of 70 and the next period, Night, is pro-
grammed for 65, scheduled to start at 11 pm. If during the Evening time period you want it warmer, press the UP button and raise the temperature above 70. The thermostat will hold that temperature until the next programmed period comes around, at which point the temper-
ature will adjust to what is programmed. In this case, the Night period is set for 11 pm and 65. Manual Mode When in the manual mode, there will be no time period displayed. Instead, the word Hold will be displayed above the Set Point tem-
perature, indicating the thermostat is holding that temperature. Adjust to the desired temperature, using the UP and DOWN buttons, and the thermostat will maintain the temperature you set until you manually change it again.

The thermostat and receiver will not operate as a system until they are linked together through the installation process. The linking process binds one or more receivers to a thermostat so that they will communicate with each other as a control system. Up to eight (8) receivers can be linked to a single thermostat. Until linked, a control receiver will not operate. Once linked, a control receiver will only respond to its specific thermostat. Link the Thermostat to the Receiver A thermostat and receiver that have been linked will not interfere with or be affected by any other thermostat or receiver in adjacent rooms, apartments or neighboring homes. Linking information is stored in memoryIt is not necessary to re-link a thermostat and receiver if the thermostat batteries are removed or after a power outage. If multiple installation teams are installing and linking thermostats at the same time, coordinate the activity to avoid the possibility of installers simultaneously attempting to perform the linking process. Because this is an RF system, installers in nearby rooms/areas where it is possible RF overlap could exist run the risk of interfering with each other. Installation and linking activity going on around a system already installed will not interfere with it. 10 49-7574 v06 6/7/07 9:44 AM Page 11 Installing or removing receiver (cont.). A. Press the SW4-INSTALL button inside the thermostat. Press the HEAT/COOL button on the front of the thermostat to select your choice. Press the UP button to set the receiver number (0-7) and press the HEAT/COOL button to set the receiver. B. Press the SW9-LINK button inside the thermostat. Within 5 seconds, press the RESET/LINK button (PB3) on the receiver. The Good message will appear if linked. The Bad message will appear if not linked. C. Press the SW4-INSTALL button to close the installation session.

SW12RESET Master Reset Returns thermostat to all factory defaults. SW4INSTALL Starts an installation session. SW9LINK Used to link the thermostat to control receiver(s). NOTE: The display always blinks the item that is active and can be changed. Uninstalling a Receiver Unlike installing a receiver, the procedure to remove will uninstall all receivers installed to the thermostat at once. You cannot remove a single receiver at a time. Step One Press the SW4-INSTALL button inside the thermostat. The Install icon will flash. Press the UP button to get the Remove choice and press the HEAT/COOL button to select. The Heat and/or Cool icons will be displayed and all display items will be on steady; nothing will be flashing. Step Two Press the SW9-LINK button on the back of the thermostat printed circuit board. Within 5 seconds, activate a Link Service Request on the receiver. When the SW9-LINK button is pressed, the thermostat will display the Please Wait message in the bottom right corner of the LCD while it searches for a receiver. Once the thermostat finds its installed receiver(s), linking information is removed from the receivers and the thermostat, the Please Wait message is extinguished and a Good message will appear. 11 49-7574 v06 6/7/07 9:44 AM Page 12 Installing or removing receiver (cont.). Thermostat Installation Reset If there is difficulty installing a receiver, perform the following:
Step One Press the SW4-INSTALL button inside the thermostat. The Install icon will flash. You only need to begin the installation session to perform this reset. Step Two Press and hold the PB1-NETWORK button on the inside of the thermostat board for approximately 2 seconds. No response is displayed. All previous installation records will be wiped from thermostat memory. You can continue from this point with the installation procedure. The PB1-NETWORK button will only reset the thermostat installation data base if the thermostat is already in an Installation Session (SW4-INSTALL button has been pressed). Otherwise, the PB1-NETWORK button will have no effect. 12 49-7574 v06 6/7/07 9:44 AM Page 13 Frequently asked questions. Where should I locate my thermostat?
For best results, the thermostat should be located approximately five feet above the floor on an inside wall in an area with good air circulation. A thermostat should not be located where air is stagnating, such as behind doors, in corners or under cabinets. Hot or cold drafts from air ducts and windows should be avoided. Avoid direct heat from the sun, lighting fixtures, appliances, fireplaces, etc. What does the antenna symbol on the display mean?
The thermostat displays the antenna symbol as indication that it is communicating with its receiver(s). If, after several tries, communication is not established, the antenna symbol will go out. What do I do if the antenna symbol is no longer displayed?
Check power to the HVAC equipment in which the receiver is installed. With power restored, force the thermostat to talk to the receiver(s) by pushing the FAN button or running the set point temperature above or below the room temperature (above in heating, below in cooling). The thermostat will also automatically try to communicate within a maximum of ten minutes from the last attempt. If communication is successful, the antenna icon will turn back on. Coincidental RF interference could cause a temporary loss of communication. In virtually all such cases, the interference is temporary. The thermostat will attempt to re-establish communication with its receiver(s) within a maximum of ten minutes. Can I run multiple heating or cooling loads such as electric baseboard heating and a window air conditioner with one thermostat?
Yes. In fact, one thermostat can control up to eight (8) different receivers. Can I use another thermostat without interference?
Yes. This wireless thermostat and its receiver(s) will talk between themselves, but will never respond to or control another thermostat in adjacent rooms, apartments or neighboring homes. When my a/c turns off, why cant I immediately make it run again?
This is normal. What you are experiencing is called an anti short-cycle delay. Because of high pressure in the system, it is not a good idea to start your air conditioner immediately after it has just shut down. The thermostat automatically prevents this from happening by imposing a delay of approximately 3 minutes. 13 49-7574 v06 6/7/07 9:44 AM Page 14 Frequently asked questions (cont.). I just installed the thermostat and the antenna symbol goes on and off. What should I do?
A weak RF signal between the thermostat and one or more receivers is the cause. The further away the thermostat and receiver are from each other, the weaker the signal. Distance and/or something shielding or blocking the RF signal is the likely cause. Distance is typically not a problem. The most common cause for this is an object acting as a shield, such as sheet metal. Changing the position of the receiver or thermostat or both may be required. In rare cases where the receiver cannot be repositioned or where it is completely enclosed in a sheet metal control box, a small section of sheet metal may need to be removed and, if necessary, replaced with plastic or other nonmetallic material. NOTE: Always seek out competent professional electrical and HVAC contractors when working with your heating and cooling system and the electrical wiring in your home or commercial property. Always consult with an HVAC contractor and/or original equipment manufacturer before modifying any equipment. The display on the thermostat is blank. What happened?
A blank display indicates that your batteries are depleted. When the Low Battery icon comes on, there is only 1 or 2 weeks of battery life remaining. (See the BATTERIES Installing/Changing section of this manual for information on how to change the batteries.) We recommend that when you change batteries, always use batteries that you know are fresh. Use four (4) new high-quality AA batteries. If you are using the wireless thermostat to control a heating system, we recommend as a general practice putting fresh batteries in at the start of the heating season. If I am away for an extended time such as a vacation, how do I set the thermostat so my system does not run excessively?
You have a couple choices. The first is to press the HEAT/COOL button on the thermostat until the display reads OFF. (Particularly during the heating season, we do not recommend going to the OFF mode.) The second option is to put your thermostat in manual mode by pressing the RUN button. You know that you are in the manual mode because none of the period icons, Morning, Day, Evening or Night will be displayed. The Hold icon located above the Set Point temperature will be displayed. Next, adjust the set point temperature to minimize system operation. For example, you could adjust to a Set Point of 85 in cooling or 65 in heating, keeping in mind what your temperature selection could affect, such as plants and animals that stay in your home while you are away. During the cooling season, consider humidity, as well as indoor temperature. When your air conditioner runs, it not only cools the air, it also removes moisture, lowering humidity. High humidity can encourage mold growth. 14 49-7574 v06 6/7/07 9:44 AM Page 15 Troubleshooting tips. Problem No display Solution Make sure batteries are fresh and installed correctly. See the Batteries section in this manual. Verify that wiring is correct. System fan does not come on properly Program schedule activates Check time (AM/PM) set on thermostat (see Programming). at the wrong time Thermostat does not follow program Fan runs continuously Verify that it is in Program mode; check time (AM/PM); check if in Manual Mode (Hold Set Point and temperature are in the display). Check Fan Auto/On switch. If set to Fan 1 or Fan 2 position, fan will run continuously. If a wired thermostat was removed, make sure that the hole in the wall was sealed with nonflammable insulation or putty, or use a wall plate obtained from a local hardware or home building store. There is a protective time delay (approximately 3 minutes) to prevent tripping of the compressor overload. For this reason, the unit may not start normal cooling or heating for 3 minutes after it is turned back on. Room temperature is not correct Compressor doesnt run or turn on immediately when changing function or setting displays on screen Time in display is not correct Replace batteries with 4 fresh AA alkaline batteries. Set clock/time. 15 49-7574 v09 6/28/07 10:51 AM Page 16 Thermostat Warranty. Staple your receipt here. Proof of the original purchase date is needed to validate the warranty. For The Period Of:
