Vent Axia Ecotronic Humidity Sensor 563532

Vent-Axia Ecotronic 563532 — Adjustable Humidity Sensor with Pullcord Override and Low/High Speed Changeover, 65–90%RH, Commercial.

The Vent-Axia Ecotronic 563532 is a wall-mounted solid-state humidity sensor with adjustable set point, designed for commercial ventilation applications where automatic humidity-responsive fan control is required. An adjustable set point solid state On/Off sensor, it can be wired into a controller Auto mode connection and incorporates a changeover switch to select low or high speed. Set point adjustment across 65–90%RH and a pullcord manual override make it a practical, flexible humidity control solution for commercial washrooms, changing rooms, kitchens and other moisture-generating environments.

Automatic Humidity-Responsive Ventilation

The sensor is adjustable from 65 to 90% relative humidity — allowing the installer to dial in the precise trigger point at which the fan switches to boost mode to suit the specific application and room volume. When relative humidity rises above the set point, the sensor switches the connected fan to high speed automatically; when conditions return below the threshold, the fan reverts to low speed without any manual intervention. This demand-controlled approach ensures effective moisture removal exactly when it is needed without running fans at full speed continuously.

Pullcord Manual Override with Lamp Indication

A pullcord provides manual override, indicated by lamp. Occupants can trigger the fan manually regardless of the measured humidity level — useful for immediate extraction at the start of an activity before moisture levels rise — and the indicator lamp provides clear visual confirmation that the override is active. This combination of automatic sensing and manual override covers both the automated compliance requirement and the practical occupant control expectation in a single unit.

Low/High Speed Selection and Controller Integration

The sensor incorporates a changeover switch to select low or high speed and can be wired into controller Auto mode connections. This makes it straightforward to integrate with compatible Vent-Axia fan controllers, enabling the humidity sensor to drive the fan directly through the controller's auto mode input without additional relay hardware. Maximum switching load is 1A inductive — suitable for the motor loads of standard commercial extract fans.
