General
Compatibility	ALB EC, KWL EC 700–2600

The temperature sensor TFR-ALB/KWL from Helios Apparatebau is designed for measuring room temperature and enables the control of a ventilation unit according to a pre-set temperature value. It is specifically designed for use with ventilation systems of the ALB EC and KWL EC 700–2600 types, with compatibility limited to specific model variants. The sensor continuously measures the current ambient temperature and transmits these readings to the control unit of the ventilation system, enabling automated control of ventilation functions.

Functions and equipment in detail
The sensor detects room temperature and transmits the measured values to the ventilation unit, which then adjusts its operating parameters according to the setpoint value. This enables targeted and energy-efficient ventilation that adapts to actual room conditions. Control is achieved via an electronic interface compatible with the control systems of the specified ventilation units.

Technology explained simply
The sensor operates as a passive measuring device that detects ambient temperature and transmits the data to the ventilation unit. Its operation is based on converting temperature into an electrical signal, which is interpreted by the ventilation unit. Ventilation adjustment occurs automatically whenever the measured temperature exceeds or falls below the setpoint value.

Compatibility and accessories
The temperature sensor TFR-ALB/KWL is intended for use with ventilation units from the ALB EC and KWL EC 700–2600 series. Installation is carried out directly onto the ventilation unit, although the exact mounting method (e.g., screw or clamp connection) is not specified.

Installation and mounting
Installation is typically performed by qualified personnel familiar with the requirements of the respective ventilation system.

Advantages in operation
Using the temperature sensor enables automated and precise control of ventilation, adapting to actual room conditions. This results in improved air quality and more efficient use of the ventilation system. Control occurs without manual intervention once the setpoint value is reached.

Installation is typically performed by skilled personnel familiar with the requirements of the respective ventilation system. The exact positioning of the sensor within the room is crucial for measurement accuracy, although no specific placement is prescribed. The sensor’s function is limited to temperature measurement and control, without additional features such as humidity sensing or air quality measurement.
