Humidity sensor KERMI RF - D275/DX/X, automatic operation option Y341100000401K

Smart humidity control with KERMI RF sensor - D275/DX/X

The KERMI RF humidity sensor - D275/DX/X is an optional control element designed to work with KERMI recuperators (except for the C225 model). Its task is to automatically adjust the recuperator's performance in response to changes in humidity levels in the room, which translates to user comfort and energy efficiency of the ventilation system.

This small but technologically advanced sensor reacts to sudden humidity spikes – typical during bathing or showering – increasing the recuperator's speed to quickly remove excess moisture. Once conditions stabilize, the device automatically returns to its previous operating mode. Thanks to this, you don't have to manually adjust the recuperator settings, and the air in your home remains fresh and healthy.

Comfort and savings in one

The sensor offers two operating modes: "eco" and "comfort", allowing you to tailor the recuperator's operation to individual needs and preferences. Choosing the appropriate mode allows you to optimize energy consumption while ensuring optimal indoor climate comfort. Importantly, using a humidity sensor can improve the energy efficiency of the ventilation system by up to one level (e.g., from A to A+).

• Automatic adjustment: The sensor automatically adjusts the recuperator's performance to the current humidity level.
• Fast response: Immediate response to humidity spikes, e.g., during bathing.
• Two operating modes: "Eco" for energy saving and "Comfort" for maximum comfort.
• Completely wireless: Facilitates installation and integration with the existing ventilation system.
• Battery powered: Thanks to power supply from 2 AA batteries, installation does not require additional wiring.

Installation and compatibility

The KERMI RF - D275/DX/X sensor is easy to install and communicates wirelessly with the recuperator. It can be mounted on the wall or ceiling (depending on the recuperator model), providing flexibility in choosing the optimal installation location. The device is compatible with all KERMI recuperators (except for the C225 model).
