Vent Axia 4 Speed Switch Temperature Humidity Sensor Wired Black 497697

Vent-Axia 497697 — 240V 4 Speed Switch with Temperature and Humidity Sensor, Wired, Black, for Sentinel Econiq MVHR Range.

The Vent-Axia 497697 is the black finish wired wall-mounted 4-speed switch combining manual speed control with integrated temperature and humidity sensing for the Sentinel Econiq MVHR range. A single faceplate provides the occupant with direct ventilation speed selection across four levels, while the built-in sensors continuously monitor the room environment and feed data back to the MVHR unit — enabling the system to respond automatically to changes in temperature and humidity without any manual intervention.

Manual Speed Control and Automatic Demand Response — Combined

Four speed settings give the occupant direct, immediate control over the ventilation rate — useful for manually boosting during cooking, bathing, or other moisture-generating activities. At the same time, the integrated temperature and humidity sensor allows the Sentinel Econiq to operate in demand-controlled ventilation mode, automatically adjusting fan speed in response to measured room conditions. Placing this sensor switch in a wet room or kitchen delivers both the occupant speed control and the automatic demand response that Building Regulations Part F and good IAQ practice require — in a single fitting. The black finish suits contemporary interiors and complements dark electrical accessory schemes.

Wired — Reliable Signal, No Battery Maintenance

The 497697 is the wired variant, using a direct 240V connection to the MVHR control system. Wired sensors provide reliable, uninterrupted signal transmission without the battery replacement requirements associated with wireless or battery-powered alternatives — making them the preferred choice for new build and social housing installations where long-term reliability and minimal ongoing maintenance are priorities.

Compact Single Gang Format

At 90×90×17mm the sensor switch occupies a standard single gang footprint and projects only 17mm from the wall surface. Temperature sensing range covers 0–60°C and relative humidity sensing covers 0–90%, encompassing all practical indoor environment conditions.
