• When synchronization is successful, the hands will move towards the correct time. If it fails
however, the hands will move towards the time that was memorized.
Reset
• To reset the time and memory, use a piece of metal (e.g. a blank paperclip) to short circuit the
two metal reset pins [A].
• All hands will move to the 12:00 position and the memory is cleared. The clock will attempt to
synchronize to the master clock.
8. Temperature indication
Refer to the illustrations on page 2 of this manual.
• On the clock face, there are two LCDs indicating the outdoor [6] and indoor [7] temperature
[Q] and trend [L]. The indoor temperature sensor is inside the clock housing and is refreshed
every 15s; the outdoor temperature is measured using a remote sensor which synchronizes
every 30s.
Remote sensor
• Make sure batteries are present inside the remote sensor and LCD battery compartment (see §10).
• Release the screw on the back of the remote sensor and set the channel selector [S4] to the
desired channel (1~3). The channel is indicated on the LCD [S1].
Note: when multiple sensors are used they must be set to different channels.
• Set the same channel on the clock using the channel selector [F]. The channel is shown [K] on
the outdoor display [6].
• Press the test button [S3] to test the link between the sensor and the clock. When everything
works fine, the link indicator [N] on the LCD [6] lights up briefly and the clock will beep once.
• Press the °C/°F selector [S5] to set the temperature scale on the remote LCD [S1] to °C or °F.
Note: this setting is only applicable for the temperature indication on the remote sensor itself,
not on the clock.
• Close the back of the sensor and secure it with the screw.
• The sensor can be used freestanding by unfolding the foldable stand [S7] or hung on the wall
by the suspension [S2]. Always placed the sensor in a location protected from rain, moisture,
splashing and dripping liquids.
General
• Set the temperature scale to °C or °F by pressing the °C/°F selector [J]. The scale is indicated
on the display [P]. Note that the setting is applicable for both indoor and outdoor temperature
indications.
• The temperature trend [L] (rising, steady, decreasing) is shown for both indoor [7] and outdoor
temperatures [6].
• To see the maximum measured temperature since last reset, press the max/min button [G]
once. Press again to see the minimum temperature since last reset.
• Press the max/min button [G] a third time to see the current temperature. Note: the
temperature indication returns to current temperature automatically after ±8 seconds.
• To reset the maximum and minimum values, press and hold the max/min button [G] for ±2s.
• When multiple sensors are used (max. 3, only 1 sensor included), press the channel selector [F]
to switch between the different remote sensors.
• To re-initialize the temperature indication completely (clear all limits and max/min values for all
channels) use a small pin (e.g. a paper clip) to press briefly on the reset button [5].
Alarm setting
• The clock can generate an alarm when a preset upper or lower temperature limit is reached.
These limits can be set individually for the 3 available sensor channels.
• Press and hold the alarm button [H] for ±2s. The upper temperature limit value and indicator
[M] start flashing on the LCD [6] (default: +70°C/ +158°F).
• When no key is touched within ±5s, the LCD will resume normal operation.
• Use the up [I] and/or down [J] button to set the desired upper temperature limit. Press and
hold the buttons will increase setting speed.
• When multiple sensors (channels) are used, press the channel button [F] to move to the next
channel and set its desired upper temperature limit.
• Press the alarm button [H] again to store the setting. The lower temperature limit value and
indicator [M] start flashing on the LCD [6] (default: -50°C/ -58°F).
