At Royal Infrared Heating®, we make smart heating control practical and convenient. The Poer 26 WiFi programmable thermostat is designed to manage electric underfloor heating, electric radiators and other compatible heating equipment. Its compact wall-mounted design, clear LCD display and flexible programming options make temperature management straightforward. With the correct installation and configuration, Poer 26 delivers dependable heating control. Electrical connections must be completed by a qualified electrician.
The Poer 26 thermostat is compatible with standard 86 mm mounting boxes and 60 mm European wall boxes. Installation involves removing the front cover, connecting the wiring according to the supplied diagrams and securing the backplate with two screws. Once fitted, configure the time, temperature and heating schedules, then connect to WiFi through the POERsmart app for remote control. Follow our step-by-step Installation Guide below for full instructions.
1. Prepare the Installation Tools
Before installing the thermostat, make sure you have the necessary tools and mounting accessories ready.
You may need a screwdriver, a suitable drill bit, a wall mounting box and the appropriate fixings for your wall type.
Please note: The drill bit, plastic wall box and installation tools are not included in the thermostat package. These can be purchased separately from Leroy Merlin or a similar hardware store.
Our friendly team is always happy to recommend the correct accessories and can even help you order everything you need for delivery directly to your home.
2. Prepare the Wall Opening
Choose a suitable position for your thermostat, away from moisture, water and condensation.
If a compatible mounting box is not already installed, a suitable wall opening must be prepared using the appropriate drilling equipment.
The thermostat is compatible with 86 mm concealed mounting boxes and 60 mm European mounting boxes.
Please note: The drill bit and plastic mounting box must be purchased separately. Our team can help you select the correct products and arrange home delivery.
Wall preparation and electrical installation should be handled by a qualified professional.
3. Drill the Wall Opening
Choose a suitable position for the thermostat and mark the location where the electrical mounting box will be installed.
Using an electric drill with an appropriate hole saw attachment, carefully create an opening in the wall.
Please note: The drill and hole saw attachment are not included in the installation set. They can be purchased separately from Leroy Merlin or a similar hardware store.
4. Prepare the Mounting Opening
Once the drilling is complete, carefully remove any loose material and check that the opening is clean and correctly sized for the electrical mounting box.
Ensure the opening is properly positioned and ready for installation.

5. Install the Electrical Mounting Box
Place a suitable plastic electrical mounting box into the prepared wall opening and secure it according to the manufacturer’s instructions.
A qualified electrician should carefully route the necessary power supply and heating cables into the box, leaving sufficient length for connection to the thermostat.
Please note: The plastic mounting box is not included in the installation set and must be purchased separately.
6. Prepare the Electrical Connections
With the mounting box securely installed, carefully position the power supply and heating cables so they are ready for connection to the thermostat.
Ensure the cables are correctly identified, properly arranged and accessible for the next installation step.
Important: All electrical work must be carried out by a qualified electrician, with the power supply completely switched off during installation.
7. Open the Thermostat Cover
Before proceeding, ensure the electrical power supply is completely switched off.
Insert a small flat-blade screwdriver into the opening at the bottom of the thermostat and gently release the front cover.
Carefully separate the front panel from the backplate to access the wiring terminals and mounting points.
8. Connect the Electrical Wiring
A qualified electrician should connect the power supply and heating system to the appropriate terminals, following the supplied wiring diagram.
Ensure all connections are correctly positioned and securely tightened before fixing the thermostat to the mounting box.
Important: The thermostat requires a 100–240V AC power supply and supports a maximum switching load of 16A. All electrical connections must be completed by a qualified electrician.
9. Secure and Set Up the Thermostat
Once the electrical connections are complete, securely attach the thermostat’s backplate to the mounting box using the two fixing screws.
Carefully refit the front cover, ensuring it clicks into place and sits firmly against the wall.
After the electrician has checked the installation and restored power, use the thermostat’s control buttons to set the time, adjust your desired temperature and configure your preferred heating schedule.
