New Tondgy G01 CO₂ monitor/alarm is used to monitoring room CO₂ level, as well as room temperature and humidity It provides one on/off output to control a ventilator with four CO₂ levels presetting. Especially i t provides both buzzer alarm and three colors backlit switching alarm.

• Design for real time monitoring room carbondioxide (CO₂) level
• NDIR infrared CO₂ sensor inside with special Self Calibration System. It makes the CO₂ measurement more accurate and more reliable in use.
• More than 10 years lifetime of CO₂ sensor
• Temperature and humidity monitoring
• Three color (green/yellow/red) LCD backlit indicating ventilation optimal/moderate/poor based on the CO₂ measurement
• Two alarm ways : buzzer alarm and back-light Colours switch
• Provide optional 1 x relay output to control a ventilator
• Easy touch button for operation
• High quality with the perfect appearance, best choice for home and office
• 220VAC or 24VAC/VDC power selectable; power adapter available; desktop and wall mounting type available
• EU standard and CE approval

D+H VRS 10 has the same functions as the REM 42 rain detector, only in an extremely compact design: The VRS 10 monitors the precipitation and transmits signals to the controller.

• For rain monitoring of ventilation flaps in conjunction with 24 V DC SHEV and ventilation control panels
• Rain signal is stored for approx. 2 minutes (rain hold time)
• Rain sensor in compact design, 24 V DC
• Heated sensor area

The D+H REM 42 rain detector is perfectly suited for rain monitoring in combination with SHEV and ventilation control panels. It is primarily used for natural ventilation.

• For rain monitoring of ventilation flaps in conjunction with 24 V DC drives and D+H control panels
• Rain signal is stored for approx. 2 minutes (rain hold time)
• Heated sensor area

The D+H WRG 82 wind/rain sensor can be set to detect six different wind strenghts and rain.

• Rain signal is stored for approx. 2 minutes (rain hold time)
• Wind switching threshold via DIP switch configurable to 4 or 6 Bft.
• Signal retention time of the wind signal for approx. 10 minutes
• In combination with WE 516, WME 43 or WRZ 8000, it is possible to continuously adjust the wind switching threshold between 2‑8 Bft.; the signal retention time can be selected between 1‑15 min.
• Heated sensor area
