8. Close the battery door. Make sure the gasket (around the battery

compartment) is properly seated in its trace prior to closing the door. Tighten

the set screw.

2.4 Display Console Set Up

1. Move the remote thermo-hygrometer(s) about 5 to 10' away from the

display console (if the sensor is too close, it may not be received by the display

console). If you have more than one thermo-hygrometer, make sure they are all

powered up and transmitting on different channels.

2. Remove the battery door on the back of the display, as shown in Figure

4. Insert four AAA (alkaline or lithium, avoid rechargeable) batteries in the back

of the display console

Figure 4

All of the LCD segments will light up for a few seconds to verify all segments

are operating properly.

3. Replace the battery door, and fold out the desk stand and place the

console in the upright position.

The console will instantly display time, indoor temperature and humidity as

designated by the icon. The remote temperature and humidity will update

on the display within a few minutes on the appropriate channel.

While in the search mode, the remote search icon will be constantly displayed.

If you have more than once remote sensor (up to eight remotes are supported),

the display will automatically toggle between sensors until all sensors have

reported in.

Do not touch any buttons until the remote sensor has reported in, or the radio

search icon is no longer on, otherwise the remote sensor search mode will

be terminated. When the remote sensor temperature and humidity has been

received, the console will automatically switch to the normal mode, and all

further settings can be performed.

If the remote does not update, please reference the troubleshooting guide in

Section 8 .

2.4.1 Display Console Layout

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 5 to 10' 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 5 to 10' apart). The sensors should be

within 2°F (the accuracy is ± 1°F). 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 north 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°F 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°F per 30 minutes (or less), or humidity is decreasing

at a rate of -5% per 30 minutes (or less).

5.7 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.

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 300 feet line of sight (no

interference, barriers or walls) but typically you will get 100 feet

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 .

5.8 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. Thus, the humidity cannot

be calibrated below 10% or above 99%.

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.

The purpose of your weather station is to measure conditions of your

surroundings, which vary significantly from location to location.

5.8.1 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 SET/ADJUST and

CLEAR/- 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

CLEAR/- button to decrease the humidity reading in 1% increments. To rapidly

increase (or decrease) the humidity reading, press and hold the CHANNEL/+

or CLEAR/- 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.

Discussion: Humidity is a difficult parameter to measure electronically

and drifts over time due to contamination. In addition, location has an adverse

affect on humidity readings (installation over dirt vs. lawn for example).

Official stations recalibrate or replace humidity sensors on a yearly basis. Due

to manufacturing tolerances, the humidity is accurate to ± 5%. To improve this

accuracy, the indoor and outdoor humidity can be calibrated using an accurate

source, such as a sling psychrometer:

or one step humidpak calibration kits (reference Section 9 ). You can

also use common table salt, water and a plastic bag:

5.8.2 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 SET/ADJUST

and CHANNEL/+ buttons at the same time for 5 seconds and the temperature

value will begin flashing. Press the CHANNEL/+ button to increase the

temperature and the CLEAR/- button to decrease the temperature reading in

0.1° increments. To rapidly increase (or decrease) the temperature reading,

press and hold the CHANNEL/+ or CLEAR/- 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.

Discussion: Temperature errors can occur when a sensor is placed too

close to a heat source (such as a building structure, the ground or trees).

To calibrate temperature, we recommend a mercury or red spirit (fluid)

thermometer. Bi-metal (dial) and other digital thermometers are not a good

source and have their own margin of error. Using a local weather station in your

area is also a poor source due to changes in location, timing (airport weather

stations are only updated once per hour) and possible calibration errors (many

official weather stations are not properly installed and calibrated).

Place the sensor in a shaded, controlled environment next to the fluid

thermometer, and allow the sensor to stabilize for 48 hours. Compare this

temperature to the fluid thermometer and adjust the console to match the fluid

thermometer.
