Illustration: the display and blue lines are schematic. Check the functions and compatibility of the chosen thermostat and receiver.
Choose a thermostat for an infrared panel by checking technical data for the whole combination. Compare our thermostats only once you know which controls your panel supports. “Infrared thermostat” is not proof of compatibility. This guide focuses on technical checks: output, load, sensor, communication and operation after installation.
Controls can reduce unnecessary heating and clarify use. They do not guarantee a fixed savings percentage or perfect temperature. Heat loss, panel output and measurement position still matter. We advise on the actual version rather than applying one standard to every panel.
Key points
Compare panel, thermostat and receiver documentation. These five checks establish whether the combination fits:
- Output: does the electrical signal suit the panel or receiver?
- Load: is the combination suitable for connected output and load type?
- Sensor: is temperature measured in a suitable position with the correct sensor?
- Communication: do transmitter, receiver and any app support each other?
- Commissioning: do the correct panels respond to heat demand and switch off again?
Have fixed connections and alterations professionally carried out. We explain these checks below.
What does an infrared-panel thermostat control?
Most room thermostats measure air temperature at the sensor and compare it with the set value. The panel emits radiation and convection. Perceived comfort therefore goes beyond the display number: surfaces, clothing, air movement and position count. A thermostat does not automatically measure all radiant comfort.
Not every controller modulates voltage or input power. A relay may switch the panel fully on and off. Programmes set desired temperatures over time; actual on-time follows from controls and heat demand. A measurement deviation does not produce the same percentage consumption change in every building.
Assessing version and communication
A plug-in thermostat can switch a suitable plug-in panel. A wired controller needs correct cabling and output. Wireless RF systems require explicitly compatible transmitters and receivers. Wi-Fi may operate through controls or a gateway. Check the diagram instead of assuming every component talks directly to the router.
Before buying, ask about supported apps, zones, receivers and account or subscription requirements. Voice control depends on the model. Consumption statistics may be calculated rather than measured electricity. Wireless controls do not have one universal interference-free distance through every wall and ceiling.
Checking your thermostat’s technical data
Output and load
Check output type, supply voltage, load type and permitted load for this application. An amperage figure alone is insufficient. Panel quantity also depends on receivers, communication and installation. Do not use a general safe limit of 3,000 or 3,680 watts without product checks. Have extra switching equipment and total circuit load assessed beforehand.
Measurement accuracy is not hysteresis
Accuracy describes measurement deviation under defined conditions. Hysteresis or switching differential concerns switching around a set value. Manufacturers may define it differently. Very small differentials may cause more switching and are not automatically better or more economical. Follow product settings.
Sensors and special applications
For electric underfloor heating, controls, temperature limits and sensors must match floor and system. A floor sensor is not interchangeable with a room sensor without checks. In a bathroom, assess every component by exact position, product approval, IP protection and electrical conditions. An IP code alone does not prove safe use in every zone.
Commissioning and checking zones
Have a qualified installer make or assess the electrical combination and fixed connection. Position the sensor representatively according to the manual, away from strong sun, draughts or local heat. Tabletop or wall mounting is only suitable if permitted for the model. Do not replace instructions with one universal mounting height.
Pair according to manufacturer procedure and test each panel separately for demand and switching off. Record receiver-to-zone assignments. Test operation without internet or on signal loss as instructed and check low-battery warnings. A radio symbol alone does not prove the output actually switches.
Programme according to room use. Different rooms may have separate settings if supported. This is not exclusive to infrared. Parts of open spaces still exchange heat. Check comfort and change one setting at a time before adding complex automation.
Our advice on your thermostat and infrared panel
We help private and business end users and support installers and wholesalers. Send panel, controller and receiver model numbers, a floor plan and operating wishes. State existing wiring or smart links. We discuss suitable options and data or checks still required.
Document settings and maintenance
Keep manuals and record zoning. Check programmes after usage changes and replace batteries as instructed. Low-maintenance does not mean connections, sensors or relays never need checks. Expected lifespan is not a warranty period; check conditions for the specific appliance.
Frequently asked questions
Can an ordinary boiler thermostat connect directly?
Not without checking output, voltage, load and supported application. A boiler control signal differs from switching an electric heating panel. Have the manufacturer combination assessed; do not add an arbitrary relay based only on wattage or a matching plug.
Product documentation and further reading
The official Alkari thermostat information describes different flush- and surface-mounted controls. This illustrates why you must check the version of an infrared-panel thermostat: communication and supply differ by model.
