6. Use
• Make sure batteries are present inside main station and external sensor (refer to §8).
• When batteries are present, the main unit will display the indoor temperature [A]. To toggle between
°C or °F display, press the °C/°F selector [D].
• Hold the external sensor ±1m (±3ft) from the main station and press the power on/off button [3].
• The local temperature is shown on the display [1]. To toggle between °C or °F display, open the
external sensor by turning the top (with antenna) counter clockwise. Press the °C/°F selector [7].
Verify that the rubber seal is in place and in good condition. Place the top back and secure it by
turning clockwise until you hear a click.
Note: when the external sensor is open, no temperature is measured or displayed.
• The external sensor will now attempt to connect to the main station. The status of the link between
the main unit and external sensor is indicated by the link status indicators on the main unit [C] and on
the external sensor [2]:
steady no signal detection
blinking sending/receiving signal
steady main and external sensor synchronized
• When the main station does not receive a (valid) signal, the outdoor temperature indication [B]
remains blank (--.-). Press the re-sync button [F] to try again.
• The external sensor will send temperature data to the main station every 3 minutes, indicated by a
blinking status LED [5] and blinking link status indicators [2] and [C].
Note: Working frequency is 433MHz. Signal transmission/reception may be interfered by other devices
using the same frequency. If this interference is temporarily, normal operation will resume once
the source of interference disappears.
• Place the main unit indoors, preferably in line-of-sight of the external sensor, but keep at least 1m
(3ft) distance from metal window frames or sources of interference e.g. computer monitors, TV-sets....
Mount the unit on the wall using the wall mounting hole [J] or flip down the foldable stand [H] and
secure it by pushing it inside the housing (see the illustration on page 2).
• Place the external sensor in a pool/hot tub/pond/…, protected from direct sunlight and (heavy) rain.
The maximum distance from the main unit is ±30m (100ft), but distance is reduced depending on the
number, size and type of obstacles between main station and external sensor.
• The maximum and minimum measured temperatures are stored in memory. To recall the memory,
press the max/min button [E] once to see the maximum [A] and minimum [B] indoor temperature.
Press the max/min button [E] again to see the maximum [A] and minimum [B] outdoor
temperature. Press again or simply wait ±10s to return to normal display.
• Press the clear button [G] to clear the maximum and minimum temperature memory.
• To reset the main station, press the reset button [K] which is located under the foldable stand [H] at
the back of the device. This will also clear the stations’ memory and re-initiates the wireless
communication link.
• When the low battery indication appears in the indoor temperature display area [A] or pool
temperature display area [B], replace the batteries of the main station respectively the external
sensor (see §8).
7. Troubleshooting
• No outdoor temperature is displayed.
• Verify whether the external sensor is on. Make sure the batteries of the external sensor are still
sufficiently charged.
• Press the re-sync button [F] and wait ±6 minutes. If this doesn’t help, verify whether the
distance between main station and external sensor is within limits and no interference is present.
