Manual temperature controls
For a straightforward local setpoint with a knob or simple keys. Specify whether the control follows room or floor temperature and whether the installation needs a separate floor limit.

An underfloor heating thermostat uses a room sensor, a floor probe or a combination of both to regulate an electric heating circuit.
About Electric Underfloor Heating Thermostats
An underfloor heating thermostat uses a room sensor, a floor probe or a combination of both to regulate an electric heating circuit. The thermostat controls the supply to the heating cable or mat; it does not produce the heat. Room control follows the air temperature at the thermostat, while floor control follows the embedded probe. A combined arrangement can regulate room comfort while applying a floor-temperature limit. The useful configuration depends on the floor covering, heating layout and whether the system provides background warmth or contributes to space heating.
Manual, scheduled and connected controls need the right sensor input and electrical interface before their display or remote features can be selected.
Product Configurations
Programmable digital thermostats
For heating schedules that follow occupancy. Discuss the daily program, temporary override, holiday behavior and the way settings should recover after an interruption to the power supply.
Enquire about this configurationTouchscreen room controls
For a screen-led interface with visible operating modes. Review mounting depth, display language, brightness and access restrictions alongside the required sensor and load connections.
Enquire about this configurationWiFi and remote-control arrangements
For projects requesting remote adjustment as well as local operation. Confirm network requirements, account ownership, supported software and the functions that remain available without an internet connection.

A matched controller and probe
Treat the thermostat and embedded floor sensor as a pair. For a replacement, send the existing probe specification and wiring information so the inquiry addresses the installed sensor rather than relying on connector appearance.
A suitable user interface
Discuss manual adjustment, timed operation and access to advanced settings. Rental properties, staffed facilities and private rooms may need different override and lock arrangements even when their heating circuits are similar.
Zone and switching design
Identify which rooms share a circuit and where the controlling sensor is located. Larger connected loads may require an external switching assembly; define its coil interface and operating sequence with the electrical designer.
Technical Information to Specify
Share these details with your inquiry. Product ratings and operating limits are confirmed for the selected configuration.
| What to specify | Unit / format | Selection guidance |
|---|---|---|
| Heating circuit supply | V / Hz | State the installation voltage and frequency, including any separate supply used by the controller. |
| Connected heating load | W / A | List every mat or cable on the zone and its combined load; identify whether switching is direct or through a contactor. |
| Control and limit temperatures | °C | Give the desired room or floor setpoint and the floor assembly's permitted temperature limit. |
| Floor probe compatibility | Ω / kΩ / °C | Provide the sensor type and resistance-versus-temperature data, especially when retaining an existing probe. |
| Mounting interface | mm | Supply wall-box dimensions, fixing centers, available depth and the permitted faceplate size. |
| Control sequence | mode / schedule | Choose room sensing, floor sensing or room control with a floor limit, together with scheduling and override needs. |
| Location and exposure | environment / °C | Describe the proposed controller location, ambient conditions and relevant wet-area installation constraints. |
| Remote access requirements | network / interface | State whether remote access is required and identify network, account, language and offline-operation expectations. |

- Electrical installation and circuit protection must follow the applicable project requirements.
Typical Applications
Cable and mat floor heating
For electric floor-heating circuits whose controller needs to match the heater load and floor build-up. Include the floor-covering supplier's limits and the heating-system layout in the selection brief.
Scheduled room heating
For rooms with predictable occupied and unoccupied periods. Supply the occupancy pattern and expected warm-up behavior so the proposed schedule is useful for the actual floor construction.
Thermostat replacement projects
For an existing installation needing a new interface or changed controls. Keep the old wiring diagram, heater rating and probe data together; a matching wall plate alone does not establish compatibility.
How to Select the Right Configuration
Identify the installed heating zone
Record heater types, electrical load, floor construction and probe position. Separate the required room temperature from the permitted floor temperature before choosing a control mode.
Check the electrical and sensing interfaces
Match supply, switching capacity, sensor characteristics and wall-box dimensions. If the thermostat drives another switching device, include that device's input and the complete control sequence.
Define everyday operation
Agree how occupants change the temperature, how schedules are overridden and who manages remote access. Include a local operating method and the intended behavior after a power or network interruption.

Frequently Asked Questions
It can be considered when the combined load, circuit arrangement and sensing strategy are suitable. Mats in rooms with different heat losses or floor finishes may need separate zones even when the total current is acceptable. Provide each mat's rating and location for a combined electrical and control review.
Only after its characteristics are matched to the replacement thermostat. Similar-looking probes can use different resistance curves. Provide the original sensor data and any measured resistance together with the temperature at the time of measurement; a reading without its temperature is incomplete.
Room control responds to air near the controller, while floor control responds to the embedded probe. A room-control mode with a floor limit can address both comfort and the floor covering's constraints. The sensor position and permitted temperature must suit the selected floor system.
The answer depends on the selected controller and software. Define which local functions must remain available offline, then confirm that behavior before ordering. Remote access, account registration and software support should be documented separately from basic temperature regulation.
A higher setpoint does not increase the installed heater's rated power. Warm-up depends on the floor construction, starting conditions and heat losses as well as the control method. Specify the expected use schedule rather than relying on an unusually high temperature setting.
