Initial use

Inserting the batteries

Before you can use the thermo hygrometer, you first have to insert two AAA batteries (included in delivery) into the battery compartment. Proceed as follows:

1. A round battery compartment lid is located on the rear of the thermo hygrometer. Twist the battery compartment lid anti-clockwise. Now remove the battery compartment lid.
2. Insert the two AAA batteries included in the delivery into the battery compartment. When inserting the batteries, pay attention to the correct polarity (+/−), as shown in the battery compartment. As soon as the batteries are correctly inserted, all display elements appear on the display for 3 seconds. The thermo-hygrometer then automatically switches to standard mode.
3. Before you replace the battery compartment lid, you first have to set the date and time. To do so, follow the instructions in the following section.

Setting the date/time/temperature unit

1. To switch between the 12- and 24-hour modes, press the [TIME] button. To switch between Celsius (°C) and Fahrenheit (°F), press the [UP/CF] button.

   The order in the settings menu is:

   Year → Month → Day → Hour → Minute

2. To access the settings menu, press and hold the [TIME] button for 3 seconds. The year starts to flash in the display.
3. Set the current year using the [UP/CF]/[DOWN] buttons. Confirm using the [TIME] button. The month now flashes in the display.
4. Now set the month, day, hour, and minute one after the other in the same manner using the [UP/CF]/[DOWN] buttons and confirm each using the [TIME] button.
5. If you do not press any buttons for 7 seconds in the settings menu, you will automatically exit the settings menu.
6. Place the battery compartment lid back on the battery compartment.
7. To close the battery compartment lid, twist it in a clockwise direction until you feel it click firmly into place. Make sure that the arrow markings of the device and the battery compartment lid line up.
8. You can use the fold-out stand to create a standalone device or you can mount it on the wall using the mounting fixture on the back of the device.

Resetting to factory settings

To reset the date and time to factory settings, briefly press the [RESET] button using a pointed object.

Usage

The thermo hygrometer has a standard mode and a timer mode.

Standard mode

If you do not press any buttons on the thermo hygrometer, the standard mode is automatically shown on the display.

Timer

You can also set a timer of up to 99 minutes on the thermo hygrometer.

1. In order to start the timer, set your desired timer duration using the [1 min] button and the [10 min] button. The set timer duration appears in the centre of the display. If you do not press any buttons for 3 seconds, the timer starts automatically with a beep. A beep sounds again when the timer elapses. To switch off the beep, press the [CLEAR] button.
2. To end a timer early, press the [CLEAR] button.

Cleaning and maintenance

IMPORTANT

• Clean the device with a damp cloth. Do not use any abrasive cleaning products or hard brushes.
• Under no circumstances may liquid enter the device.
• If you do not plan to use the device for a long period of time, we recommend that you store it in the original packaging in a dry environment, ensuring it is not weighed down by additional items.

Troubleshooting Beurer Thermo Hygrometer HM 22: Common Issues and Solutions

Encountering problems with your Beurer Thermo Hygrometer HM 22? Most issues are simple to resolve. If the display is blank, check and replace the 2x 1.5V AAA LR03 batteries, as low power is the primary cause—batteries are included initially but drain over time. For inaccurate readings, ensure the device is away from direct sunlight, drafts, or heat sources; calibration isn't user-adjustable, but accuracy is factory-set at ±1°C (0-40°C) and ±5% RH (40-80%).

No specific error codes are listed, but if the timer fails to signal, verify settings via touch buttons and reset by removing batteries for 1 minute. Humidity readings outside 20-95% may show limits—place in stable conditions for stabilization. Preventive measures: Avoid extreme temperatures beyond -10°C to +50°C, clean the housing with a dry cloth, and store batteries separately when unused.

For persistent issues, contact Beurer support via their website (beurer.com) or local distributors. The 3-year warranty covers defects; retain proof of purchase. Email customer service at service@beurer.com or check the manual for regional hotlines—quick resolutions ensure continued reliable indoor temperature and humidity tracking.
