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.

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 4.

4 Display Console Set Up

Move the remote sensor(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 remote sensor, make sure they are all powered up and transmitting on different channels. Remove the battery door on the back of the display, as shown in Figure 5.

Figure 5

Remove the battery cover, and insert two AAA (alkaline or lithium, avoid rechargeable unless fully charged and high quality) batteries in the back of the display console. All of the LCD segments will light up for a few seconds (to verify all segments are operating properly).

1. Replace the battery door, and place the console in the upright position with the desk stand folded out.

The console will instantly display time and indoor temperature as designated. The remote temperature 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.

Version 1.0 ©Copyright 2017, Ambient LLC. All Rights Reserved. Page 6

Do not touch any buttons until the remote sensor has reported in, or the radio search icon is no longer constantly on, otherwise the remote sensor search mode will be terminated.

When the remote sensor temperature 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.

Version 1.0 ©Copyright 2017, Ambient LLC. All Rights Reserved. Page 9

1. If a specific channel is lost, press the CH/+ button to display this channel, then Press and hold the CH/+ button for 3 seconds, and the remote search icon will be constantly displayed for up to 3 minutes. Once the signal is reacquired, the remote search icon will turn off, and the current values will be displayed.

2. If new sensors are added, subtracted, or multiple sensor channels are lost, press and hold the

CH/+ button for 5 seconds (on any channel), 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.

5.5.2 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.

The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction decreases the transmission range by the factor shown below.

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.

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

Version 1.0 ©Copyright 2017, Ambient LLC. All Rights Reserved. Page 10

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.

5.6.1 Remote Sensor Temperature Calibration

Prior to entering the calibration mode, press the CH/+ button to select the remote temperature sensor you wish to adjust.

To enter the temperature calibration mode, press and hold the SET and CH/+ buttons at the same time for 5 seconds and the SENSOR temperature value will begin flashing. Press the CH/+ button to increase the temperature and the MIN/MAX button to decrease the temperature reading in 0.1° increments. To rapidly increase (or decrease) the temperature reading, press and hold the CH/+ or

MIN/MAX button.

To return the temperature to the actual or uncalibrated measurement, press the SET button.

Once the displayed temperature equals the calibrated source, press and hold the SET button for three seconds, or wait 15 seconds for timeout, and the temperature value will stop flashing.

5.6.2 Indoor (Console) Temperature Calibration

To enter the indoor temperature calibration mode, press and hold the SET and MIN/MAX buttons at the same time for 5 seconds and the INDOOR temperature value will begin flashing. Press the CH/+ button to increase the temperature and the MIN/MAX button to decrease the temperature reading in

0.1° increments. To rapidly increase (or decrease) the temperature reading, press and hold the CH/+ or

MIN/MAX button.

To return the temperature to the actual or uncalibrated measurement, press the SET button.

Once the displayed temperature equals the calibrated source, press and hold the SET 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.

Problem Solution

Wireless remote (thermo-hygrometer) not reporting in to console.

There are dashes (--.-) on the display console.

Temperature sensor reads too high in the day time.

If any of the sensor communication is lost, dashes (--.-) will be displayed on the screen. To reacquire the signal, press and hold the CH/+ button for 3 seconds, and the remote search icon will be constantly displayed.

Once the signal is reacquired, the remote search icon will turn off, and the current values will be displayed.

The maximum line of sight communication range is 300’ and 100’ under most conditions. Move the sensor assembly closer to the display console.

If the sensor assembly is too close (less than 5’), move the sensor assembly away from the display console.

Make sure the remote sensor LCD display is working and the transmitter light is flashing once per 60 seconds.

Install a fresh set of batteries in the remote thermo-hygrometer. For cold weather environments, install lithium batteries.

Make sure the remote sensors are not transmitting through solid metal (acts as an RF shield), or earth barrier

(down a hill).

Move the display console around electrical noise generating devices, such as computers, TVs and other wireless transmitters or receivers.

Move the remote sensor to a higher location. Move the remote sensor to a closer location.

Make sure the thermo-hygrometer is mounted in a shaded area on the north facing wall. Consider the following radiation shield if this is not possible: http://www.ambientweather.com/amwesrpatean.html

Version 1.0 ©Copyright 2017, Ambient LLC. All Rights Reserved. Page 13

Problem

Indoor and outdoor temperature do not agree

Solution

Allow up to one hour for the sensors to stabilize due to signal filtering. The indoor and probe temperature sensors should agree within 4 °F (the sensor accuracy is ± 2 °F).

Use the calibration feature to match the indoor and probe temperature to a known source.

Display console contrast is weak Replace console batteries with a fresh set of batteries.
