ECOAIR EVO HT Soler & Palau bathroom fan with timer and humidistat sensor

The ECOAIR EVO HT offers all the benefits of the ECOAIR EVO ST, with the added intelligence of a built-in humidistat for automatic boost mode activation.
The ECOAIR EVO is a decentralized mechanical extract fan designed for continuous ventilation and superior indoor air quality in bathrooms, kitchens, and utility spaces. Operating in a constant volume trickle mode, it quietly removes stale air and humidity, and can be switched to a boost mode via an external switch (3-wire connection) or timer when extra airflow is needed.
Featuring a modern onboard control panel and digital display, it offers real-time monitoring of humidity, flow rate, and motor runtime. The EC motor ensures long-lasting, silent, and low-energy performance, consuming as little as 2–4.5 W depending on speed. Trickle airflow can be adjusted between 18–58 m³/h, and boost mode delivers up to 108 m³/h at a maximum sound level of just 34.6 dB(A).
With IP45 protection, Class II insulation, and ultra-low noise starting from 9 dB(A), the ECOAIR EVO ST is an ideal solution for spaces that require smart, discrete, and highly energy-efficient ventilation.

Models:
ST: Standard Model with Timer. This has several operating modes to vary the speed of the fan and a timer.
HT: Relative Humidity Sensor Model with Timer. This has several operating modes to vary the speed of the fan and a timer but adds a humidistat sensor.

The electrical connection can be with two wire for an autonomous and automatic operation mode (HR model) or three-wire connection must be used in order to force the product to switch from low to high speeds (ST model).

DISPLAY – OPERATING INFORMATION MENU:
This menu will be activated when any key is pressed for more than 3 seconds, this shows the operating information of the product:
• Running time of the motor in years, weeks, days and hours
• The instantaneous flow rate
• The instantaneous relative humidity (HT version)
