Panasonic FV-CSVK1 Condensation Sensor Module for WhisperGreen Select

Overview

The Panasonic FV-CSVK1 Condensation Sensor Module works with WhisperGreen Select exhaust fans to actively manage bathroom humidity. It senses relative humidity and temperature to anticipate dew point, automatically increasing airflow when moisture rises for steadier air and a more comfortable space.

Designed for seamless integration, this condensation sensor adds a responsive control layer to WhisperGreen Select fans without requiring a full replacement. When moisture levels climb, the module can elevate fan speed across the multi-speed range to deliver more air where it matters most, helping to balance comfort and energy use.

Fine-tuned humidity control

The built-in RH sensitivity adjustment lets you tailor the sensor’s reaction for your space. This is helpful in rooms with varying moisture patterns and supports CAL Green requirements. In practice, you can set a proactive response for busy bathrooms or a more modest setting in drier spaces.

Smart timing for steady comfort

In addition to automatic activation, the module includes a 20-minute delay off timer. This keeps the fan running briefly after moisture levels drop, helping stabilize airflow and reduce temperature swings after showers or laundry tasks.

Installation and versatility

Installation is straightforward for WhisperGreen Select compatibility. You can select up to three of four plug-in modules to customize your ventilation, with the condensation sensor available as one option. The result is a tailored ventilation profile that fits your daily routine without complex wiring.

Why it fits today’s homes

Quiet operation, responsive sensing, and flexible module options address everyday needs: rapid humidity response after a shower, steady air freshness in busy bathrooms, and alignment with CAL Green criteria. Panasonic emphasizes reliable ventilation solutions that adapt as your space changes.
