IMPORTANT: Read entire instructions before starting the
installation. Leave installation instructions with owner af-
ter performing installation.

SAFETY CONSIDERATIONS

Read and follow manufacturer instructions carefully. Fol-
low all local electrical codes during installation. All wiring
must conform to local and national electrical codes. Im-
proper wiring or installation may damage thermostat.
Recognize safety information. This is the safety alert sym-
bol . When the safety alert symbol is present on equip-
ment or in the instruction manual, be alert to the potential
for personal injury.
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety alert sym-
bol. DANGER identifies the most serious hazards which will
result in severe personal injury or death. WARNING signi-
fies a hazard which could result in personal injury or death.
CAUTION is used to identify unsafe practices which would
result in minor personal injury or property damage.

GENERAL

The wireless, 7-day, commercial, programmable ther-
mostats maintain room temperature by controlling the

Wireless Transmitter
operation of an HVAC (heating, ventilation, and air condi-
tioning) system. Separate heating and cooling set points and
auto-changeover capability allow programming of 4 differ-
ent time periods for energy savings.
All thermostats allow up to 4 time/temperature settings to
be programmed per 24-hr period. Each thermostat stores pro-
grams for 7 independent days. Batteries are required for op-
eration. During power interruption (batteries removed) the
internal memory stores configuration and comfort schedules
for an unlimited time. The clock will need to be reset
everytime power is lost (batteries changed).
The wall mounted or hand-held transmitter sends its sig-
nal to a receiver installed near the HVAC unit. Each trans-
mitter and receiver can be given a separate house code for
multiple thermostat applications. Up to 4 transmitters can
send information to one receiver device.
The thermostat can be configured to accept several
different equipment configurations, including heat pump
operation.
IMPORTANT: The transmitter and receiver are factory con-
figured with a house code of 0. If more than one set of
wireless transmitters and receivers are used in the same
location, the house codes must be different for the ther-
mostats to communicate properly.

INSTALLATION

Install Batteries -

Two AA lithium batteries are in-
cluded with the transmitter. Remove the back cover and in-
stall batteries. To ensure proper operation, only use AA lithium
batteries as replacements.

Select Transmitter Location (Optional) -

transmitter is wireless and no mounting or wiring of the trans-
mitter is required. However, if a mounting location is de-
sired for the transmitter, the transmitter should be mounted:
• approximately 5 ft from the floor
• close to or in a frequently used room, preferably on an
inside partitioning wall
• on a section of wall without pipes or ductwork
• where temperature operating limits are within 41 to 104 F
(5 to 40 C)
• where humidity operating range is within 0 to 95% rela-
tive humidity, non-condensing
The thermostat should NOT be mounted:
• close to a window, on an outside wall, or next to a door
leading to the outside
• where exposed to direct light and heat from a lamp, the
sun, a fireplace, or any other temperature-radiating object
which may cause a false reading
