Heatmiser Floor Sensor 3m
Genuine Heatmiser MISC 103 Sensor
The Heatmiser MISC 103 provides remote temperature sensing for compatible Heatmiser heating controls.
Heatmiser designed the probe primarily for floor temperature measurement. However, compatible thermostats can also use it for remote air sensing.
Therefore, one compact sensor can suit several heating-control applications.
10K NTC Temperature Probe
The MISC 103 uses a 10K NTC sensor rated at 25°C.
Its manufacturer specification is R25 = 10K ±1%. Therefore, it provides the correct resistance characteristics for compatible Heatmiser controls.
Always confirm thermostat compatibility before installation.
3 Metre Sensor Cable
Heatmiser supplies the probe with a 3 metre PVC cable.
Therefore, it provides useful installation flexibility between the thermostat and sensing point.
If extra length is required, Heatmiser allows the cable to extend up to 20 metres using suitable twin shielded cable.
Designed for Floor Temperature Sensing
The MISC 103 is specifically designed for use as a floor sensor.
When installed with a compatible thermostat, it can provide floor temperature information to the heating control.
This can be particularly useful where the thermostat needs to monitor or limit floor temperature rather than relying only on room air temperature.
Install the Sensor in Conduit
Heatmiser recommends installing the sensor inside a suitable conduit when it measures floor temperature.
The conduit helps protect the probe during installation. In addition, it makes future removal or replacement much easier.
Therefore, installing conduit during the initial floor build-up can save considerable work later.
Floor or Remote Air Measurement
The probe can perform two different sensing roles.
It can measure floor temperature when installed within the floor structure.
Alternatively, a compatible Heatmiser thermostat can use it as a remote air sensor.
The exact operating mode depends on the thermostat and its configuration.
Compatible Heatmiser Thermostats
Heatmiser states that the MISC 103 works with its thermostats that support a remote sensor connection.
Verified compatible Heatmiser ranges include:
- neoStat
- neoStat 12V
- neoStat-e
- neoStat Pro
- neoStat Touch
- neoStat Touch-e
- neoStat Ultra
- neoStat WiFi
- Edge
- Edge-E
- Slimline
- Slimline-E
- Slimline-N
- Slimline-RF
- Touch v2
- Touch-E v2
- Touch-Duo
- Touch-N
- NeoAir
- SmartStat
The manufacturer’s current compatibility chart confirms these models.
Check Compatibility Before Ordering
Not every Heatmiser thermostat accepts this wired remote probe.
For example, Heatmiser’s published compatibility chart lists DS1, DS1-L, Slimline-B, neoStat-hw, Slimline-HWN and Touch-RF as incompatible.
It is also not compatible with the Heatmiser fan coil HC range.
Therefore, always check the thermostat model before ordering.
Ideal Replacement Floor Sensor
The MISC 103 also works well when replacing a damaged compatible Heatmiser probe.
Its manufacturer code makes the correct replacement easier to identify.
If an existing sensor cable has already been installed inside conduit, replacement can also be considerably easier.
Suitable for Water Underfloor Heating Controls
The probe can work with compatible Heatmiser thermostats used on water underfloor heating systems.
For example, the current Heatmiser neoStat v3 supports compatible NTC floor probes.
Therefore, installers can use remote sensing where the thermostat and system configuration support it.
Suitable for Electric Floor Heating Controls
The MISC 103 can also work with compatible electric floor heating thermostats.
For example, Heatmiser’s neoStat-e supports floor sensing and is supplied with a 3 metre remote floor sensor.
As a result, the MISC 103 provides a useful genuine replacement sensor for compatible installations.
Temperature Range
Heatmiser specifies an operating sensor range of -20°C to 80°C.
Therefore, the probe covers the temperatures normally encountered in floor and remote heating-control applications.
Compact Probe Design
The sensing probe measures approximately 6.5mm in diameter and 20mm long.
Meanwhile, the cable measures approximately 3.3mm in diameter.
Its compact design makes it practical to route through suitable sensor conduit.
No Polarity Required
Heatmiser confirms that the sensor wiring has no polarity.
Therefore, either sensor wire can connect to either relevant sensor terminal on a compatible thermostat.
Always follow the thermostat wiring instructions.

Why Use a Floor Sensor?
A room thermostat normally measures the surrounding air temperature.
However, floor temperature can differ significantly from room temperature.
A remote floor sensor gives a compatible thermostat additional information from within the floor structure.
Therefore, the thermostat can use the floor reading where its control settings support this function.
Why Buy From Kudos Trading?
Kudos Trading supplies Heatmiser controls for water and electric underfloor heating systems.
Our range includes thermostats, wiring centres, sensors, actuators and smart-control accessories.
Therefore, installers can source the sensor alongside compatible Heatmiser controls from one supplier.
