2.4.2 Sensor Operation Verification
Verify the indoor and outdoor humidity match closely with the console
and sensor array in the same location (about 1.5 to 3 meters apart).
The sensors should be within 10% (the accuracy is ± 5%). Allow about
30 minutes for both sensors to stabilize. The humidity can be adjusted
or calibrated later to match each other a known source.
Verify the indoor and outdoor temperature match closely with the
console and sensor array in the same location (about 1.5 to 3 meters
apart). The sensors should be within 2°C (the accuracy is ± 1°C). Allow
about 30 minutes for both sensors to stabilize. The temperature can be
adjusted or calibrated later to match each other or a known source.
3. Remote Sensor Installation
It is recommended you mount the remote sensor on a south facing
wall, in a shaded area. Direct sunlight and radiant heat sources will
result in inaccurate temperature readings. Although the sensor is water
resistant, it is best to mount in a well protected area, such as under an
eve. Use a screw or nail (not included) to affix the remote sensor to the
wall, as shown in Figure 6.
Figure 6

4. Display Features
4.1 Comfort Icon
The comfort icon is based on humidity ranges specified in Figure 7 .
The icon is displayed for indoor humidity, remote channel 1 humidity
and optional remote channels 2 through 8 humidity.
Figure 7
4.2 Rate of Change Icon
The rate of change icon detects rapid changes in temperature and
humidity. If the arrow points upward, the temperature is increasing at a
rate of +2°C per 30 minutes (or greater), or humidity is increasing at a
rate of +5% per 30 minutes (or greater). If the arrow points downward,
the temperature is decreasing at a rate of -2°C per 30 minutes (or less),
or humidity is decreasing at a rate of -5% per 30 minutes (or less).
5. Console Operation
Note: The console has three buttons for easy operation:
MIN/MAX/- button, CLEAR/ADJUST button, and CHANNEL/+ button.

are lost, press the CHANNEL/+ button until the indoor channel
is displayed. Press and hold the CHANNEL/+ button for 3
seconds, and the remote search icon will be constantly
displayed for up to 10 minutes. Once the signal is reacquired, the
remote search icon will turn off, and the current values will be
displayed.
5.5 Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls
and metal barriers. We recommend the following best practices for
trouble free wireless communication.
-9-

1. Electro-Magnetic Interference (EMI). Keep the console several
feet away from computer monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 433
MHz devices and communication is intermittent, try turning off
these other devices for troubleshooting purposes. You may
need to relocate the transmitters or receivers to avoid
intermittent communication.
3. Line of Sight Rating. This device is rated at 100 meters line of
sight (no interference, barriers or walls) but typically you will get
30 meters maximum under most real-world installations, which
include passing through barriers or walls.
4. Metal Barriers. Radio frequency will not pass through metal
barriers such as aluminum siding. If you have metal siding,
align the remote and console through a window to get a clear
line of sight .
5.6 Adjustment or Calibration
Note: The calibrated value can only be adjusted on the console.
The remote sensor(s) always displays the un-calibrated or measured
value.
Note: The measured humidity range is between 10 and 99%.
Humidity cannot be accurately measured outside of this range.
The purpose of calibration is to fine tune or correct for any sensor error
associated with the devices margin of error. The measurement can be
adjusted from the console to calibrate to a known source.
Calibration is only useful if you have a known calibrated source you
can compare it against, and is optional. This section discusses
practices, procedures and sources for sensor calibration to reduce
manufacturing and degradation errors. Do not compare your readings
obtained from sources such as the internet, radio, television or
newspapers. They are in a different location and typically update once
per hour.
-10-

The purpose of your weather station is to measure conditions of your
surroundings, which vary significantly from location to location.
5.6.1 Humidity Calibration
Prior to entering the calibration mode, press the CHANNEL/+ button to
select the humidity sensor you wish to adjust.
To enter the humidity calibration mode, press and hold the
ADJUST and MIN/MAX buttons at the same time for 5 seconds
and the humidity value will begin flashing. Press the CHANNEL/+
button to increase the humidity and the MIN/MAX/- button to
decrease the humidity reading in 1% increments. To rapidly
increase (or decrease) the humidity reading, press and hold the
CHANNEL/+ or MIN/MAX/- button.
To return the humidity to the actual or uncalibrated measurement,
press the ADJUST button.
Once the displayed humidity equals the calibrated source, press
and hold the ADJUST button for three seconds, or wait 15
seconds for timeout, and the humidity value will stop flashing.
5.6.2 Temperature Calibration
Prior to entering the calibration mode, press the CHANNEL/+ button to
select the temperature you wish to adjust.
To enter the temperature calibration mode, press and hold the
ADJUST button for 5 seconds and the temperature value will begin
flashing. Press the CHANNEL/+ button to increase the temperature
and the MIN/MAX/- button to decrease the temperature reading in
0.1°C increments. To rapidly increase (or decrease) the temperature
reading, press and hold the CHANNEL/+ or MIN/MAX/- button.
To return the temperature to the actual or uncalibrated measurement,
press the ADJUST button.
Once the displayed temperature equals the calibrated source, press
and hold the ADJUST button for three seconds, or wait 15 seconds for
timeout, and the temperature value will stop flashing.
