PRE-ALARM FUNCTION FOR
CHANNEL 1 REMOTE SENSOR
The alarm function also has a pre-alarm feature which can alert the
user before the preset alarm time when weather condition changes.
This pre-alarm function applies to Channel 1 Remote Sensor
only.
To enable this function:
1. First activate the alarm function. Then enter the Pre-Alarm
mode by pressing the [
] button twice. The "PRE-AL" icon
will be displayed.
2. Press and hold the [
] button for 3 seconds to set the
operating time interval for this pre-alarm function. Use the
[ ] or [ ] button to select from the 4 time-intervals: 15, 30,
45 or 60 minutes.
3. Press the [
] button to confirm and exit. The pre-alarm
function will be enabled automatically which is indicated by
the appearance of the [
] symbol.
4. To disable this function, press the [ ] button in the Pre-Alarm
mode. The [ ] symbol will disappear and [ - : -- ] will appear
to indicate disable of this function.
The pre-alarm will operate during the selected time interval before
the daily alarm time.
During the pre-alarm operating period, if the temperature recorded
at Channel 1 remote sensor falls to or below 2.0ºC, the pre-alarm
will be triggered. For example, if the daily alarm is set to go off
at 7:00 am and the pre-alarm operating time interval is set to 45
minutes, the pre-alarm will start to operate at 6:15 am (45 minutes
before 7:00 am). The Pre-Alarm icon will flash and the backlight
will be turned on for 5 seconds. An alarm sound will also go off
for 2 minutes as that of the daily alarm and the snooze function
will also be activated if the [ SNOOZE / LIGHT ] button or stand-
button is pressed.
Note: The daily alarm will NOT function until the next day if the
pre-alarm has been triggered beforehand. Deactivation of the
alarm function will disable the pre-alarm feature automatically.
NOTE ON REMOTE READINGS
Once batteries are in place in the remote unit, it will start
transmitting samplings at 40-second intervals. If no signals are
received when the remote sensor display is selected, "--- " will be
displayed. To force the main unit to search for remote sensor
signals, press [ MEMORY ] and [ CHANNEL ] simultaneously.
If that fails, check that the remote sensor is still in place. Make
sure the transmission is within range and the path is clear of
obstacles and interference. Repeat this procedure whenever you
find discrepancies between the display on the main unit and the
display on the remote sensor.
CHECKING INDOOR AND REMOTE
TEMPERATURES & HUMIDITIES
To display the indoor and outdoor temperature and humidity
readings, press the [ CHANNEL ] button to toggle among the
indoor, Channel 1, 2 and 3 displays.
