Installing/ChangingA low battery icon will light on the thermostat display when the batteries are within aweek or two of being exhausted. The thermostat is designed to use standard AA-size 1.5 voltbatteries. If the batteries are depleted, the heating/cooling system will go to the OFF state.Replacing BatteriesTo open the thermostat, remove the security screw (#2 Phillips or #2 security screw). Using both hands, pressthe two push-tabs on the bottom of the thermostat housingwith your thumbs, while pulling the front of the thermostataway from the base.The thermostat operates with 4 AA batteries.Batteries are paired, one set on topof the other.4Introduction.This two-part wireless thermostat system is designed to provide precision temperature controlwithout the installation headaches and expense of wiring. Powered by four AA batteries, thethermostat will operate for approximately 1 year, and can be mounted in any suitable locationthat will ensure good temperature control. A large LCD display provides the user with currentspace temperature, set point temperature, time, program interval and other system statusinformation. The second part of the system is the receiver. The receiver interfaces with thedesired HVAC equipment and communicates with its thermostat using unlicensed 900MHzradio frequency energy. At the time of installation, the thermostat is linked to one or morereceivers. A thermostat and receiver that have been linked will not interfere with or be affectedby any other thermostat or receiver in adjacent rooms, apartments or neighboring homes.Batteries.ThermostatcoverLatchesBase plateThermostat will operateon either Set A, Set B orboth.

Pressing the UP or DOWN button will toggle betweenthe weekday icons and the weekend icons. Ensure the display is blinking the one you want toprogram. Press HEAT/COOL.Step TwoNext, 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 ThreeNext, 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 FourThe minute of the day will blink next. This is the starting minute in the hour. Use the UP orDOWN button to change the minute digits to the desired setting. (Note that minutes change in five-minute increments.) Press HEAT/COOL.Step FiveThe desired set point will now be blinking. This is the temperature you want the thermostat togo to at the time of day you have selected. Press the UP or DOWN button to change to thedesired set point temperature. Press HEAT/COOL.This completes the programming of the first period of the day.Step SixIf you started with the Morning time period, the next period, Day, will now be blinking. Followsteps two, three, four and five for each period you wish to program.49-7574 v06 6/7/07 9:44 AM Page 8
Navigating.You can quickly step through to a specific item you want to change by pressing theHEAT/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, saveyour changes to memory and return you to normal thermostat operation.Run button – program/manual operation.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 ModeOne of the four periods, in this case “Day,” is displayed, letting youknow 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 programmedset 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 itwarmer, press the UP button and raise the temperature above 70°. The thermostat will holdthat 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 ModeWhen 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 willmaintain the temperature you set until you manually change it again.Fan AutoDay11:20 AMTh HEAT71OOSet PointFan Auto11:20 AMTh HEATOFF70OOSet PointHold949-7574 v06 6/7/07 9:44 AM Page 9
10Installing or removing receiver.The thermostat and receiver will not operate as a system until they are linked together throughthe installation process. The linking process binds one or more receivers to a thermostat so thatthey will communicate with each other as a control system. Up to eight (8) receivers can belinked 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 ReceiverA thermostat and receiver that have been linked will not interfere with or be affected by anyother thermostat or receiver in adjacent rooms, apartments or neighboring homes. Linkinginformation is stored in memory—It is not necessary to re-link a thermostat and receiver if thethermostat batteries are removed or after a power outage.If multiple installation teams are installing and linking thermostats at the same time, coordinatethe activity to avoid the possibility of installers simultaneously attempting to perform the linkingprocess. Because this is an RF system, installers in nearby rooms/areas where it is possible RFoverlap could exist run the risk of interfering with each other. Installation and linking activitygoing on around a system already installed will not interfere with it.49-7574 v06 6/7/07 9:44 AM Page 10

13Frequently asked questions.“Where should I locate my thermostat?”For best results, the thermostat should be located approximately five feet above the floor on aninside wall in an area with good air circulation. A thermostat should not be located where air isstagnating, such as behind doors, in corners or under cabinets. Hot or cold drafts from air ductsand 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 itsreceiver(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 setpoint 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 minutesfrom 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 neverrespond to or control another thermostat in adjacent rooms, apartments or neighboringhomes.“When my a/c turns off, why can’t I immediately make it run again?”This is normal. What you are experiencing is called an anti short-cycle delay. Because of highpressure in the system, it is not a good idea to start your air conditioner immediately after ithas just shut down. The thermostat automatically prevents this from happening by imposing a delay of approximately 3 minutes.49-7574 v06 6/7/07 9:44 AM Page 13
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 furtheraway the thermostat and receiver are from each other, the weaker the signal. Distance and/orsomething shielding or blocking the RF signal is the likely cause. Distance is typically not aproblem. 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 caseswhere the receiver cannot be repositioned or where it is completely enclosed in a sheet metalcontrol box, a small section of sheet metal may need to be removed and, if necessary, replacedwith plastic or other nonmetallic material.NOTE: Always seek out competent professional electrical and HVAC contractors when workingwith your heating and cooling system and the electrical wiring in your home or commercialproperty. Always consult with an HVAC contractor and/or original equipment manufacturerbefore 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 arefresh. Use four (4) new high-quality AA batteries. If you are using the wireless thermostat tocontrol 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 mysystem does not run excessively?”You have a couple choices. The first is to press the HEAT/COOL button on the thermostat untilthe 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 pressingthe 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 Pointtemperature 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 thatstay in your home while you are away. During the cooling season, consider humidity, as wellas indoor temperature. When your air conditioner runs, it not only cools the air, it also removesmoisture, lowering humidity. High humidity can encourage mold growth.1449-7574 v06 6/7/07 9:44 AM Page 14
