OPERATING YOUR THERMOSTAT AND REMOTE SENSOR

Be sure that the remote sensor is set for the proper

identification (A, B or C for indoor or O for outdoor) and

the thermostat and remote sensor are set to the same

frequency.

On the thermostat, enter the thermostat Configuration

Menu by pressing the SYSTEM button to OFF and then

momentarily pressing

and at the same time.

Momentarily press SYSTEM button to advance to step 2

of the Configuration Menu. The display will show “LER”

and “OFF”.

Momentarily press

or to select “LER” and “On”.

The display will flash “LER” with “On” displayed con-

stantly.

On the wireless remote sensor, enter the Installer

Configuration Menu by pressing

and for five

seconds. The remote sensor display will change to

“LEARN OFF”.

Momentarily press

or to select “LEARN On”.

Exit the menu. The sensor will begin the Learn mode.

After the thermostat has successfully identified the

remote sensor in approximately one minute, the sensor

information will be stored and the thermostat display will

change to “LER” and “OK”.

If the identification sequence is not successful after ten

minutes, the thermostat display will show “LER”, “Fault” and

the antenna icon. If the Learn Mode is unsuccessful, refer to

Troubleshooting section, Antenna + Fault.

If you are replacing a thermostat that has more than one

wireless remote sensor, the Learn Mode must be performed

for each sensor. Once a sensor has been identified, it will

remain in the thermostat memory until the Learn Mode is

performed again and a different sensor for the stored

channel is identified.

Wireless Remote Indoor

Temperature Averaging

Your thermostat is designed to sense the temperature of

the indoor remote sensor and average or weight it with the

local sensor in the thermostat for each program period. The

averaging will only be active when both the local and the

indoor remote sensors are functional and turned on in the

configuration menu. When the thermostat is placed in view

schedule mode (press PRGM once), the weight of the

indoor remote sensor will be shown on the left side of the

display when HOLD button is pressed. The weighting

classes of the indoor remote sensor are designated as A

(default for average weight), HI (high weight), or LO (low

weight). The HI weight is two times the weight of A (aver-

age). The A weight is two times the weight of LO. The weight

of the local sensor is fixed to A (average weight).

The actual temperature displayed, in the clock digits, in the

normal operation mode is the mathematical weighted sum

of the enabled functioning sensors. For example, if the local

sensed temperature is 80°F and the remote sensed

temperature is 70°F then:

If weight selected is HI , then the averaged temperature is

(2 x (80°F) + 4 x (70°F))/ 6 = 73.3°F.

If weight selected is A , then the averaged temperature

is (2 x (80°F) + 2 x (70°F))/ 4 = 75°F.

If weight selected is LO , then the averaged temperature

is (2 x (80°F) + 1 x (70°F))/ 3 = 76.6°F.

The example above shows that the weight selected would

prioritize the overall averaged temperature between the two

sensors. The high weight selection caused the remote

sensor to carry more weight in the calculated temperature

average than the local sensor. The low weight selection

caused the remote sensor to carry less weight in the

calculated temperature average than the local sensor.

Choose the Fan Setting (Auto or On)

Set the FAN Switch to Auto or On.

Fan Auto is the most commonly selected setting and runs

the fan only when the heating or cooling system is on.

Fan On runs the fan continuously for increased air circula-

tion or to allow additional air cleaning.

Choose the System Setting

(Heat, Off, Cool, Auto, Emer)

Press the SYSTEM button to select:

Heat: Thermostat controls only the heating system.

Off: Heating and Cooling systems are off.

Cool: Thermostat controls only the cooling system.

Auto: Auto Changeover is used in areas where both heating

and cooling may be required on the same day. AUTO allows

the thermostat to automatically select heating or cooling

depending on the indoor temperature and the selected heat

and cool temperatures. When using AUTO, be sure to set the

Cooling temperatures more than 1° Fahrenheit higher than

the heating temperature.

Emer: Setting is available only when the thermostat is

configured in HP1 or HP2 mode.

Manual Operation for

Non-Programmable Thermostats

Press the SYSTEM button to select Heat or Cool and use

the

or buttons to adjust the temperature to your

desired setting. After selecting your desired settings you can

also press the SYSTEM button to select AUTO to allow

the thermostat to automatically change between Heat and

Cool.

Manual Operation (Bypassing the Program)

Programmable Thermostats

Press or and adjust the temperature wherever you

like. Then press HOLD. This will override the program. The

HOLD feature bypasses the program and allows you to

adjust the temperature manually, as needed. Whatever

temperature you set in HOLD will be maintained 24 hours a

day, until you manually change the temperature or press

RUN to cancel HOLD and resume the programmed sched-

ule.

Program Override (Temporary Override)

Press or buttons to adjust the temperature. This will

override the temperature setting for a (default) four hour

override period. The override period can be shortened or

lengthened by adjusting the temporary hold time in the

configuration menu.

Example: If you turn up the heat during the morning pro-

gram, it will be automatically lowered later, when the

temporary hold period ends. To cancel the temporary setting

at any time and return to the program, press RUN.

If the SYSTEM button is pressed to select AUTO the

thermostat will change to Heat or Cool, whichever ran last. If

it switches to heat but you want cool, or it changes to cool

but you want heat, press both

and buttons simulta-

neously to change to the other mode.
