Floor sensor SALUS FS 300, cable length 3 m, model 80FS300

The SALUS FS 300 floor sensor (model 80FS300) is a wired underfloor temperature probe with a 3 m connection cable, designed to measure and monitor surface temperature in electric and hydronic underfloor heating systems. It connects to compatible SALUS thermostats and control units to provide reliable floor temperature readings for accurate regulation and protection against overheating. The slim probe housing and flexible cable allow installation beneath floor coverings or in designated sensor pockets within screeds.

Advantages

The SALUS FS 300 provides precise floor temperature measurement with a durable wired connection that resists signal interference and does not require batteries. Its 3 m cable length offers flexibility in placement relative to the thermostat or control panel. The sensor is compatible with common SALUS controllers and designed for unobtrusive installation under a variety of floor finishes. Reliable monitoring reduces the risk of floor overheating and supports stable room comfort when used as part of an underfloor heating control loop.

Suitable for

• Electric underfloor heating systems requiring a dedicated floor temperature probe
• Hydronic (water-based) underfloor heating installations with a sensor pocket
• Integration with SALUS thermostats and control units for floor temperature regulation
• Renovation projects where discreet temperature monitoring under floor coverings is needed

Key specifications

• Sensor type: wired floor temperature probe
• Cable length: 3 m, flexible connection cable for placement options
• Probe form factor: slim housing suitable for embedding under floor coverings or in sensor pockets
• Measurement purpose: surface/floor temperature monitoring to prevent overheating and enable accurate control
• Compatibility: designed for use with compatible SALUS thermostats and control units

How to use

Install the floor sensor in a designated sensor pocket or below the floor covering at the location recommended by the underfloor heating design. Route the 3 m cable to the thermostat or control unit and connect to the designated sensor input following the controller manufacturer’s wiring diagram. Ensure the probe is positioned flat against the floor or within the pocket to obtain accurate surface temperature readings. After connection, configure the thermostat to use the floor probe input and verify temperature readings and control responses according to the control unit’s setup procedure.

Usage recommendations

Place the sensor where it represents typical floor conditions — avoid positioning directly over heating pipes or immediately adjacent to heat sources. For screed installations, use a protective tube or pocket to allow sensor replacement without breaking the floor. Follow SALUS thermostat documentation for wiring polarity, input selection, and calibration checks to ensure stable temperature regulation.
