3.3 Sensor Operation Verification
Verify the humidity sensors match closely with all of the sensors in the same location (about 5 to
10’ apart). The sensors should agree within 10% (the accuracy is ± 5%). Allow about 30 minutes
for all sensors to stabilize. The humidity can be adjusted or calibrated later to match each other
a known source.
Verify the temperature sensors match closely with all of the sensors in the same location (about
5 to 10’ apart). The sensors should be within 2°C (the accuracy is ± 1°C). Allow about 30 minutes
for all sensors to stabilize. The temperature can be adjusted or calibrated later to match each
other or a known source.
3.4 Radio Controlled Clock (RCC)
After the remote sensor is powered up, the sensor will transmit weather data for 30 seconds, and
then the sensor will begin radio controlled clock (RCC) reception. During the RCC time reception
period (maximum 5 minutes), no weather data will be transmitted to avoid interference. Once
the radio controlled time is received the RCC signal received successfully, the RCC reception
icon will turn on in the outdoor sensor LCD display. Then outdoor sensor sends the RCC signal
to display console, Once the radio controlled time is received, RCC reception icon will turn
on in the display console. (reference Figure 10).
If the signal reception is not successful within 3 minute, the signal search will be cancelled and
will automatically resume every six hours until the signal is successfully captured. The regular RF
link will resume once RCC reception routine is finished. In some locations, RCC reception may
take a couple of days to receive the signal.
4. Remote Sensor Installation
Before mount the units, ensuring that the receiver can still pick up the signal from transmitters. It is
recommended to mount the sensors on a north facing wall, in a shaded area. Direct sunlight and
radiant heat sources will result in inaccurate temperature readings. Although the sensors are
water resistant, it is best to mount in a well protected area, such as under an eve.
1. Use a screw or nail to affix the remote sensor to the wall, as shown in Figure 7
2. Hang the remote sensor up on string, as shown in Figure 8.
