Initial operation

Use a pen (e.g. ballpoint pen) to open the device. Push the round button at 

the back and simultaneously slide the back of the housing to the left. Putting 

the thumb into the USB recess may help.

slot in the direction indicated by the arrow, with the labelled side facing up. 

Make sure that the card is inserted completely.

Note: Recording of the measured values starts automatically after insertion 

of the microSD-card. The symbol 

 appears on the display. This may take 

several minutes, depending on the selected measurement interval. 

1. Push the locking button

2. Simultanously slide the back to the left

Wall mounting

To mount the device on the wall, use the notches provided in the lower 

part of the rear of the device. The notches can easily be perforated, e.g. with 

a small screwdriver. Use fl at head screws to avoid damage to the batteries.

All connectors (alarm, external temperature sensor and mini USB) and the 

opening for the internal sensor should be freely accessible. Use a pen or 
crochet hook to remove the device from the wall bracket.

Setup

Confi guration can be carried out using the buttons on the device, with the 

IR remote control, or via PC software.

Confi guration on the device

Push buttons are located on the front of the device, left and right of the 

IR sensor. To prevent tampering, the buttons can only be pressed with a 

paper clip or similar tool. The left button corresponds to the remote control’s 

button arrow up “

“. The right button corresponds to the remote control’s 

“+“ button.

After 4 seconds without user input, the menu navigation aborts without 

saving values and the display shows the current temperature and humidity.

MIN / MAX

Shows the measured minimum and maximum values since the last reset or 

battery change.

RES - Alarm acknowledge (reset)

Confi rms an existing alarm, i.e. the device deactivates the alarm output. The 

device reactivates the alarm output again as soon as the alarm limits are 

exceeded. A delay time can be set in the menu item “DLY” to prevent the 

device immediately triggering an alarm (e.g. when the show case is open).

CLK - Date and time setting

Date and time adjustment in the order: YR: Year, Mon: Month, Day: Day, HR: 

Hour in 24h format, MIN: Minutes. Confi rm with button ”

“, the display 

shows  “OK“.

Note: The device has no time zone information. To ensure that the times in 

the PC software are displayed correctly we recommend entering Coordinat-

ed Universal Time (UTC). The PC software automatically sets the device time 

as UTC. Thus local times can be calculated if the device is used to document 

international transports across time zones. The PC software automatically 

displays local times, based on the UTC time of the device.

Coordinated Universal Time (UTC) is Central European Time (CET) minus 1 

hour and Central European Summer Time (CEST) minus 2 hours.

ALM - Alarm

Defi nes the alarm limits. First set MIN/MAX temperature, then MIN/MAX 

humidity. Confi rm with the “

“ button. The display shows “OK“. The active 

alarm limits are saved on the microSD-card and preserved even during a 

battery change.

DLY - Alarm Delay

Delays alarm trigger, e.g. during transport to the device’s destination or 

while a show case adjusts to the desired climate. Select a value in hourly 

increments and confi rm with the “

“ button.
