Introduction
The BRESSER Temeo Quadro Temperature Station is designed to monitor temperature and humidity at up to four different locations simultaneously. This system includes a main display unit and three remote sensors, allowing you to track environmental conditions both indoors and outdoors, or in various rooms of your home. The remote sensors transmit data wirelessly to the main unit via a 433 MHz radio signal.

- Mounting Hole: For wall mounting.
Setup
1. Battery Installation
- For Remote Sensors:
- Open the battery compartment cover on the back of each remote sensor.
- Insert 2x AAA (LR03) batteries into each sensor, observing the correct polarity (+/-).
- Set the channel switch (1, 2, or 3) on each sensor to a unique channel.
- Close the battery compartment cover.
- For Main Display Unit:
- Open the battery compartment cover on the back of the main unit.
- Insert 3x AAA (LR03) batteries, observing the correct polarity (+/-).
- Close the battery compartment cover. The main unit will power on and begin searching for sensor signals.
2. Sensor Pairing
- After installing batteries in both the sensors and the main unit, the main unit will automatically attempt to connect with the remote sensors.
- Ensure the remote sensors are within range (typically up to 30 meters in open air) of the main unit during initial setup.
- The corresponding channel numbers (1, 2, 3) on the main unit's display will show readings once a connection is established. The 'IN' channel displays the main unit's internal readings.
- If a sensor does not connect, remove and reinsert its batteries, then press the 'CHANNEL' button on the main unit to initiate a new search.
3. Placement
- Place the main unit indoors in a central location, away from direct sunlight or heat sources.
- Position remote sensors in desired monitoring areas. For outdoor use, place sensors in a sheltered spot to protect them from direct rain and sun, which can affect accuracy and device longevity.
Operating Instructions
Viewing Temperature and Humidity
- The main display unit continuously shows the current temperature and humidity for the internal sensor ('IN') and the three remote sensors (1, 2, 3).
- The display also indicates comfort levels (e.g., 'COM' for comfortable, 'DRY' for dry, 'WET' for wet) based on humidity levels.
MAX/MIN Records
- Press the MAX/MIN button once to display the maximum temperature and humidity recorded since the last reset.
- Press the MAX/MIN button a second time to display the minimum temperature and humidity recorded.
- To clear the MAX/MIN records, press and hold the MAX/MIN button for approximately 3 seconds while MAX or MIN values are displayed.
Temperature Unit Selection (°C/°F)
- On the main unit, press the SET button to toggle between Celsius (°C) and Fahrenheit (°F).
Setting Alarms (if applicable)
- Press the ALARM button to enter alarm setting mode.
- Use the CHANNEL and MAX/MIN buttons to adjust the desired high and low temperature/humidity alarm thresholds for each channel.
- Press ALARM again to confirm settings and activate the alarm. An alarm icon will appear on the display.
- When an alarm threshold is met, the unit will emit an audible alert and the corresponding channel's reading will flash.
Maintenance
- Cleaning: Wipe the device with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries when the low battery indicator appears on the display. Always replace all batteries in a unit at the same time.
- Storage: If storing the device for an extended period, remove all batteries to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit. | Batteries are dead or incorrectly inserted. | Check battery polarity and replace with fresh AAA batteries. |
| Remote sensor not displaying data on main unit. | Sensor out of range, incorrect channel setting, or dead batteries. |
|
| Inaccurate readings. | Sensor exposed to direct sunlight, heat sources, or moisture. | Relocate sensors to a more appropriate, sheltered environment. Allow time for readings to stabilize. |
| Intermittent signal loss. | Interference from other electronic devices or physical obstructions. | Move the main unit or sensors away from potential sources of interference (e.g., TVs, microwaves, large metal objects). |
