This guide will guide you through the different steps necessary to carry out this operation, including the choice of equipment, the preparation of the installation, the connection of the different elements, as well as tests to verify the proper functioning of your system.
Choosing the right wireless thermostat
Before installing a wireless thermostat, it is crucial to choose a model compatible with your boiler. THE wireless thermostats come in several versions, offering varied features such as weekly scheduler, connection to voice assistants and much more. Popular brands include Netatmo, Nest and Honeywell.
Be sure to check compatibility with your boiler by consulting the user manual or visiting the manufacturer's website. Some thermostats also require a relay module to properly interact with your boiler.
Preparation of equipment
Once you have chosen your thermostat, gather all the equipment needed for installation. You will need:
- THE wireless thermostat and its receiver
- Batteries for the thermostat (if necessary)
- A screwdriver
- Cables (supplied with the thermostat)
- Optionally, a wire stripping tool
Cut off the power supply
To avoid any risk of electric shock, cut off the power supply to your boiler. You can do this by turning off the appropriate circuit breaker on the main electrical panel. If you are unsure of the procedure, consult a professional electrician.
Install the thermostat receiver
Receiver location
The wireless thermostat receiver should be installed near the boiler, usually on the wall or somewhere easily accessible. This small device will serve as a communication bridge between the thermostat and the boiler.
Connecting the cables
Open the receiver panel and identify the connection terminals. Typically, you will see labels like "NO" (Normally Open), "NC" (Normally Closed), and "COM" (Common). Follow the specific instructions provided with your thermostat to connect the boiler wires to the correct terminals.
Use a screwdriver to secure the cables firmly. If necessary, strip the ends of the wires before attaching them. Make sure each wire is securely connected to avoid any communication issues.
Configure the wireless thermostat
Inserting the batteries
If your thermostat runs on batteries, insert them following the manufacturer's instructions. Batteries must be of good quality to ensure optimal operation and prolong the life of the thermostat.
Synchronization with receiver
Once the batteries are in place, it's time to synchronize the thermostat with the receiver installed near the boiler. Typically this is done by holding a sync button on the receiver until a signal (light or sound) indicates the connection is established. Refer to your thermostat manual for precise steps.

Fix the thermostat
Choosing an ideal location
To ensure accurate temperature readings, choose a central location in your home at eye level, away from heat sources, windows, and drafty areas. This will ensure that the measured temperature is representative of the ambient temperature in your home.
Wall mounting
If your thermostat is designed to be wall mounted, use the mounting kit provided. Drill holes where indicated, insert wall plugs if necessary, then screw in the thermostat bracket. Finally, clip the thermostat onto its support.
Reconnect the power supply
After attaching the thermostat and checking all connections, you can reconnect the electrical power to the boiler by turning the appropriate circuit breaker back on. Make sure everything is working properly before moving on to the next step.
Test the installation
Turn on the boiler
Turn on your boiler and check that the indicator lights and display are working correctly. Set the thermostat to a different temperature than the current one to see if the boiler turns on or off accordingly.
Test settings
Check thermostat settings by testing different features, such as time programs, Eco and Comfort modes, and manual temperature adjustments. Make sure each feature triggers the expected response from the boiler.
Optimize thermostat settings
Weekly programming
To maximize energy efficiency, use your thermostat's weekly schedule feature. Define time periods where heating should be more intensive (for example, in the morning and evening) and others where it can be reduced (for example, while you are at work).
Remote control
If your thermostat supports remote controls via a mobile app, set up this feature so you can adjust the temperature in real time, even when you’re away from home. This can be especially helpful for those days when your plans change at the last minute.
Maintenance and Troubleshooting
Regular Checks
Perform regular checks to ensure your thermostat and receiver are still working properly. Replace the batteries if necessary and make sure nothing is interfering with the wireless connection.
Common Problems and Solutions
If you have connection or functionality issues, check your thermostat’s user manual. Here are some common problems and solutions:
- Loss of connection: Check the thermostat’s batteries and make sure nothing is blocking the wireless signal between the thermostat and receiver.
- Incorrect settings: Double-check the thermostat settings and make sure they are configured correctly to activate the boiler according to your needs.
- Wiring Errors: Inspect the connections at the receiver and the boiler. A loose wire can cause communication issues.
Benefits of a Wireless Thermostat
Installing a wireless thermostat has many benefits. It improves your home's temperature control, helps save energy, and provides added convenience with smart and remote features.
On top of all that, a wireless thermostat can extend the life of your boiler by optimizing its use, reducing wear and tear and maintenance requirements.
