Local signalling and limit settings
- The device operates independently, without OPC UA or MQTT network integration. It is not an Ethernet sensor designed for direct data collection into a SCADA system.
- The alert threshold can be set between 700 and 3000 ppm. Once this threshold is reached, a visual alarm is activated, along with an optional audible alarm.
- Twelve LEDs indicate the time remaining in the last hour; the digital display shows the last two hours before ventilation is required and also displays the current concentration.
- In the range of 400–5000 ppm, the maximum error is ±100 ppm + 5 per cent of the measured value. Values are updated every 10 seconds; a resolution of 1 ppm does not represent the measurement accuracy.
Commissioning and accessories
Place the monitor in a suitable location within the measurement area and connect the supplied USB power supply. The cover allows for both wall mounting and magnetic attachment, for example to a whiteboard. Use the touch controls to set the threshold, display mode and, if required, an audible alarm.

Frequently Asked Questions
Does Timeair support Ethernet, OPC UA or MQTT?
This model is intended for local display and signalling. It does not feature a network interface for OPC UA or MQTT integration.
Does the timer need to be set according to a fixed schedule?
The indicator is based on the measured CO₂ concentration and its trends, rather than on a fixed, recurring ventilation interval.
What is included in the power supply?
The package includes a 5 V / 1 A USB power adapter and a 1.8 m USB cable with a Micro-USB connector.
