The Frequency Master is a software-controlled climate controller that uses unprecedented silence to allow connected fans to do their job. The Frequency Master is equipped with two sockets and has a 5-metre-long temperature sensor (NTC) and a 5-metre-long light sensor. The frequency controller can be operated with just three simple buttons (minimum speed, maximum speed and desired temperature). The software then determines the frequency required to maintain the temperature at the set point.

The Frequency Master ensures absolutely silent and hum- or buzz-free operation of the connected fan(s). It is the most optimal way to control an AC motor. The built-in temperature control software ensures faster response times, lower idle speeds and improved accuracy for the very best results from this type of controller.

Night mode
Humidity can rise significantly at night. To keep this humidity within acceptable values, you can choose to use night mode. The Frequeny Master switches up in small steps twice an hour for a few minutes to a maximum rate of 80%. Which reduces the moisture in the air.

To use the night mode, simply remove the rubber cap from the light sensor. The Frequency Master now operates in night/day mode. The green LED now lights up. Indicates that the Frequency Master is in night mode.

To turn off the night mode, switch off the Frequency Master. Place the rubber cap over the light sensor, wait 5 seconds and switch the Frequency Master back on. The night mode is now switched off. The green LED is now switched off.

Note: If the Frequency Master is set too low, this may lead to damage and even failure of the fan(s). So make sure that the minimum level is not set too low.
