Introduction.
This two-part wireless thermostat system is designed to provide precision temperature control
without the installation headaches and expense of wiring. Powered by four batteries, the
thermostat will operate for approximately 1 year, and can be mounted in any suitable location
that will ensure good temperature control. 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 HV C equipment and communicates with its thermostat using unlicensed 900MHz
radio frequency energy. t the time of installation, the thermostat is linked to one or more
receivers. 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.

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 DOW 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.
The RU 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 whi e 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.

Installing or removing receiver.
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
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 memory—It is not necessary to re-link a thermostat and receiver if the
thermostat batteries are removed or after a power outage.
If mu tip e insta ation teams are insta ing and inking thermostats at the same time, coordinate
the activity to avoid the possibi ity of insta ers simu taneous y attempting to perform the inking
process. Because this is an RF system, insta ers in nearby rooms/areas where it is possib e RF
over ap cou d exist run the risk of interfering with each other. Insta ation and inking activity
going on around a system a ready insta ed wi not interfere with it.

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. 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. void 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 HV C equipment in which the receiver is installed. With power restored,
force the thermostat to talk to the receiver(s) by pushing the FA 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 can’t 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.
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?”
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: lways seek out competent professional electrical and HV C contractors when working
with your heating and cooling system and the electrical wiring in your home or commercial
property. lways consult with an HV C contractor and/or original equipment manufacturer
before modifying any equipment.
“The display on the thermostat is blank. What happened?”
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 “B TTERIES –
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 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 RU 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.
