ELSNER 71302 KNX eTR gl-jet black RAL 9005 temperature sensor with automatic control

The KNX eTR gl temperature sensor, model 71302, is an innovative device designed to measure ambient temperature and regulate heating and cooling systems efficiently.

Key Features

This sensor, available in the RAL 9005 jet black color, offers a series of features that make it ideal for applications in domestic and commercial environments.

Temperature Measurement

The KNX eTR gl measures room temperature precisely, covering a range from -5°C to +60°C.

Mixed Values

The sensor can receive external temperature values via bus and combine them with its own data to obtain an overall temperature value. The proportions between internal and external measured values can be set as a percentage.

PI Control for Heating and Cooling

The device is equipped with an integrated PI controller for regulating heating and cooling systems. The control can be performed in one or two steps, both for heating and cooling, based on separate target temperature values or a base temperature.

Configuration and Communication

<p-The configuration of the KNX eTR gl sensor is carried out using the KNX ETS software. The device supports up to 254 group addresses and 254 assignments, with 41 communication objects.

Food and Consumption

The sensor operates with a nominal voltage of 30 V SELV and has a maximum consumption of 10 mA. The connection is via KNX terminals or spring terminals for rigid and flexible conductors.

Start-up and Communication Time

After the bus voltage is restored, the device enters an initialization phase lasting about 5 seconds, during which it cannot receive or transmit information via bus.

Installation and Maintenance

The sensor is supplied with four screw anchors and four flat screws for mounting. For maintenance, it is advisable to clean the glass panel with a damp cloth or microfiber cloth, avoiding the use of abrasive agents or aggressive detergents.

Temperature Control Mode

• Comfort: when you are present
• Standby: when you are absent
• Eco: like night mode
• Frost/heat protection (building protection): for example when the window is open

The parameters for temperature control include setpoint temperatures for individual modes. The modes can be selected manually or automatically, for example through a timer or window contact.
