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

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

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.

6.3 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.

Verify the indoor and outdoor temperature match closely with the console and sensor array in the same

location (about 1.5m to 3m apart). The sensors should be within 4°F(the accuracy is ± 2°F). Allow

about 30 minutes for both sensors to stabilize.

7. Indoor Sensor Installation

Indoor use only. It is recommended you mount the Indoor sensor on a north facing wall, in a

shaded area. Direct sunlight and radiant heat sources will result in inaccurate temperature read-

ings. Use a screw or nail (not included) to affix the indoor sensor to the wall, as shown in Figure
