Setup Procedure
For best operation:
1. Assign different channels to different remote units.
2. Insert batteries for remote unit before doing so for
the main unit (see battery installation section).
3. Place the main unit as close as possible next to
the remote unit, reset the main unit after installing
batteries. This will ensure easier synchronization
between the transmission and reception of signals.
4. Position the remote unit and main unit within
effective transmission range, which in usual
circumstances, is 20 to 30 meters.
Note: that the effective range is vastly affected by the
building materials and where the main unit and remote
units are positioned. Try various set-ups for the best
results.
GETTING STARTED
Once batteries are in place for the remote units, they
will start transmitting temperature readings at 30-second
intervals.
The main unit will also start searching for signals for
about 2 minutes once batteries are installed. Upon
successful reception, the individual channel temperatures
reading will be displayed on the top line and the
respective humidity reading on the bottom line. The
main unit will automatically update its readings at about
30-second intervals.
If no signals are received, blanks “- - -” will be displayed
and the kinetic wave icon will not show.
To force a signal search:
• Press and hold IN/REMOTE for 2-seconds to enforce
a 3-minute search.
This is useful in synchronizing the transmission and
reception of the remote and main unit.
Repeat this step whenever you find discrepancies
between the reading shown on the main unit and that on
the respective remote unit.
HOW TO CHECK REMOTE AND INDOOR
TEMPERATURES
Display of readings from a remote sensor or the main
unit is a one step procedure. The remote sensor channel
or the main unit display is indicated in a box under the
kinetic wave icon.
To display temperature/humidity readings from the main
unit:
• Press IN/REMOTE until the dot is displayed in the box
under the kinetic-wave.
To display temperatures/humidity readings from a remote
sensor:
• Press CHANNEL until the appropriate remote sensor
channel is displayed in the box under the kinetic-wave.
If no readings are received from one particular channel
for more than 15 minutes, blanks, “- - -” will be displayed
until further readings are successfully searched. Verify
the remote unit is sound and secure.
HOW TO READ THE KINETIC WAVE DISPLAY
The kinetic wave display shows the signal receiving
status of the main unit. There are three possible forms.
COMFORT LEVEL ICONS
The comfort level is based on the recorded relative
humidity. An indicator will be displayed or show if the
level is comfortable, wet or dry.
TEMPERATURE AND HUMIDITY TREND INDICATORS
NOTE: If the temperature goes above or below the
temperature measuring range of the main unit or the
remote unit (stated in specifications), the display will
show “HHH” or “LLL”.
REMOTE SENSOR SCANNING
This unit can be set to automatically scan and display
readings from the remote sensors. When the remote-
sensor mode is active, the display will show the readings
from one channel for about 4-seconds and then proceed
to the next channel display.
To activate the remote-sensor scanning mode:
• Press and hold CHANNEL for 2 seconds.
To deactivate the remote-sensor scanning mode:
• Press any button.
MAXIMUM AND MINIMUM TEMPERATURE AND
HUMIDITY
The maximum and minimum recorded temperatures and
humidity will automatically be stored in memory.
To display the Min/max readings:
1. Select the channel to be checked.
2. Press MEM/CLEAR once to display the maximum
temperature/humidity. Press again to display the
minimum temperature/humidity. The respective
indicators (MAX or MIN) will be displayed.
To clear the memory:
Press and hold the MEM/CLEAR for 2-seconds.
HOW TO USE CHANNEL-1 TEMPERATURE/HUMIDITY
ALARM
Upper and lower temperature and humidity limits for
channel-1 can be set so that an alarm activates when the
limits are exceeded.
The high and low temperature and humidity displays are
selected sequentially pressing HI/LO.
The high-low displays are as follows:
To set the alarm:
1. Press HI/LO, channel-1 will be displayed.
2. Press ▲to set the temperature or humidity limit. Each
press will increase increments by 1° or %RH.
