Want to connect a thermostat to an infrared panel? Start with the specifications of the panel, thermostat and any receiver. Not every combination is suitable. We help you choose the right controls; the product manuals determine how the selected components may be connected and used.
This explanation helps you prepare and choose products. It is not a universal wiring diagram or a guide to electrical work. Have fixed wiring and changes to the installation assessed and carried out by a qualified installer.
Key points
- Check that the panel, thermostat and receiver are demonstrably compatible.
- The rated switching load and permitted load type of the specific product are decisive.
- An installer assesses the connection, wiring, protection, protection class and mounting location.
- Position the temperature sensor according to the instructions for the chosen controls.
- App functions, wireless pairing and energy information vary by model.
What does the thermostat do?
A room thermostat measures the temperature and controls the heating according to the configured settings. This may be directly, through a separate receiver or through another combination permitted by the manufacturer. Some panels have built-in controls. First check which controls are already present and whether an external thermostat is permitted.
Suitable controls help you adapt heating use to the room and your presence. Operation depends on the panel, measurement location, settings and heat loss. A thermostat does not guarantee a fixed saving, higher electrical conversion efficiency or a particular payback period.
Room-by-room control
Separate controls can be practical when rooms are used at different times. For example, discuss how you use your infrared heating in the living room and the heating in a study. Not every wireless system supports multiple zones or multiple receivers; check the capabilities of the specific combination.
Compatibility and electrical assessment
Check the documentation to see whether the thermostat is intended to control this electric heating. A thermostat for a central heating boiler is not automatically suitable for switching an infrared panel. A matching supply voltage or a familiar brand alone does not prove compatibility either.
Switching load of the selected components
The rated switching load, permitted load type and any conditions relating to operating duration are specified in the product data. Have the total connected load assessed against that data. There is no general maximum that applies to all thermostats and receivers.
Whether a separate relay, contactor or multiple receivers are needed depends on the selected equipment and installation. Simply adding an extra relay does not automatically make a combination suitable. Have this solution assessed too, and use only an arrangement permitted by the manufacturers concerned.
Wiring, earthing and protection
The installer assesses matters including the available power supply, load on the installation, connection method, cable selection, electrical protection and the equipment’s protection class. Whether and how protective earth must be connected follows from that protection class and the product instructions. We do not provide a universal conductor cross-section, terminal layout or connection sequence here.
Use in a damp room requires a separate assessment of mounting location, zone, protection and connection. An IP rating alone does not give general permission for installation. See our information on infrared heating in the bathroom and have the specific installation assessed.
Choosing a suitable control method
A plug-in solution
A suitable plug-in thermostat or receiver may be a practical solution for certain panels. Check whether the manufacturer permits this combination and whether the product, load and mounting location are suitable. An existing socket is not suitable for every heating arrangement without assessment. Follow the operating instructions; do not modify plugs, cables or protective devices yourself.
A wireless thermostat with receiver
In some systems, a separate thermostat measures the temperature and controls a receiver. Check the exact model, supported communication protocol, pairing options and permitted location for the receiver. RF or WiFi on the packaging does not mean components work together.
A receiver must not simply be concealed behind a panel or inside a flush-mounted box. Available space, heat, range and permitted mounting are assessed for each product. Pairing and resetting follow the relevant manual; there is no universal button sequence or reset duration.
Wired controls
For a fixed connection, the installer determines which arrangement is suitable and follows the diagrams for the products concerned. Not every thermostat switches the panel load directly. The dimensions of flush-mounted boxes, wiring and connection points also depend on the version and installation.
Controls for electric underfloor heating
Underfloor heating controls may have different requirements from controls for wall or ceiling panels. Check the required sensor and temperature limiting for the heating system and floor finish. A fault or missing sensor must not be addressed by bypassing a required protective function.
Positioning the thermostat and sensor
Place the sensor where it provides a representative measurement, following the manufacturer’s instructions. Direct radiation from a panel, sunlight, draughts and other heat sources can affect the measurement. A fixed mounting height or distance does not apply to every control system and room.
The position is tailored to the room layout and the chosen ceiling heating or wall heating. An external sensor is an option only if the system supports it. Check operation after installation and again after changes to the arrangement.
If behaviour is unexpected
If the panel continues heating when it should not, switch off the heating using the designated controls and have the cause assessed. If you suspect an electrical fault, stop using the system until a qualified installer has checked it. Do not open a receiver or thermostat to repair a relay or wiring yourself.
Advice on choosing
We help private and business end users, installation companies and other business partners select suitable controls. Send us the brand and model of the panel, the available product documentation, the number of panels and their power ratings, and your intended use. Photos of the room and information about the existing installation can help with preparation.
View our range or contact us if you are unsure about a combination.
Apps and smart controls
Check each model for the required app, network connection, account terms and functions. Support for a voice assistant, geofencing, multiple zones or an energy consumption overview is not a given. An indication of consumption is also not the same as a separate measurement of the electricity actually used.
Discuss your controls with us
Based on your information, we suggest a suitable combination and explain which installation assessment is needed. Running costs and any savings depend on heat loss, settings, operating duration and the system used for comparison.

Frequently asked questions about connecting a thermostat
Does every thermostat work with every infrared panel?
No. Check the exact models, control method and permitted load. We help you select a combination based on the product documentation.
Can I control several panels with one thermostat?
That depends on the controls and permitted arrangement. Have the total load and required receivers or other components assessed. The sum of the wattages alone does not establish whether the complete installation is suitable.
Can I use my existing smart thermostat?
This must be investigated for each version. Not every boiler thermostat can control electric heating. Even with an extra relay, not every combination is permitted.
How do I pair or reset wireless controls?
Use only the manual for the thermostat and receiver concerned. Ask us for the correct documentation if you do not have it. Have the cause assessed if faults recur.
What should I do if the panel does not switch off?
Switch off the heating using the designated controls. Have its operation checked and stop using the system if you suspect a fault. Do not repair internal electrical components yourself.
Does a new thermostat always save energy?
No. Suitable controls can better adapt usage to your needs. The outcome depends on the existing situation, settings and actual use. We do not specify a fixed savings percentage or payback period.
