Technical Specifications - Velleman WS1170 Notice D'emploi

 The alarm will automatically reactivate once the value has
fallen below the set temperature value or if a new value is
entered.
The outdoor weather alarm
When a set outdoor alarm has been triggered, it will flash on the
LCD display. The general outdoor alarm icon and HI / LO alarm
icon will flash accordingly. Example: In outdoor temperature
mode, the dew point icon will flash along the outdoor alarm and
the HI alarm icons when the dew point HI alarm is triggered.
This will indicate that the current alarm source is from the dew
point.

humidity maximum – Indoor temperature maximum – Outdoor humidity maximum – Outdoor
temperature maximum – Pressure maximum.
 In MIN mode, press + to display the following minimum values with their time and date: Indoor humidity
minimum – Indoor temperature minimum – Outdoor humidity minimum – Outdoor temperature minimum
– Pressure minimum.
 Press SNOOZE / LIGHT to return to the normal display mode
Reset
The SET button resets the values in MIN or MAX mode. To reset the values:
 In MIN or MAX mode, press and hold SET for 2 seconds to reset the MIN or MAX values and h-the time

e. Calibrating Indoor and Outdoor Humidity
The WS1170 weather station allows you to calibrate both the indoor and the outdoor humidity. Humidity is
a difficult parameter to measure accurately. The calibration option allows you to zero out this error. Note
that you will need a hygrometer calibration pack (not included).
Proceed as follows:
1. Press SET and select the indoor humidity function.
2. Press + or MIN / MAX to increase or decrease the humidity setting in increments of 1 % until the setting
matches the calibrated humidity source.
3. Press and hold SET for 3 seconds to confirm.
4. Do the same for the outdoor humidity function.
Note: The remote outdoor sensor will not display the calibrated humidity level but only the measured
humidity level. The dew point calculation is based on the calibrated humidity level.
