Salus offers a wide range of thermostats that connect to your boiler and allow you to control the temperature remotely using your smartphone. In this review, we’re going to take a look at the range as a whole, with a special focus on the catchily named Salus iT800 Wifi Smart Thermostat.

Salus thermostats are incredibly popular in the marketplace due to their low price point and simplicity. There are a lot of more advanced thermostats on the market that offer additional functions but the Salus has been a popular choice for a long time for the price-conscious and those who don’t want to mess about with gadgets that control their heating.

What is a Thermostat?

A thermostat is simply a device for controlling temperature. A thermostat reacts to temperature changes in a room to turn itself on or off automatically to match the selected setting you choose.

Many thermostats use a simple function of expansion and contraction based on heating and cooling to create or break electrical circuits, thereby turning your thermostat on or off.

Other thermostats use devices like thermistors, semiconductors, and thermocouples to detect the temperature without the need for moving parts.

Traditional thermostats are devices fixed to the wall with a temperature dial you can turn clockwise or anticlockwise to change the temperature. They are physically wired into the Boiler, controlling the temperature directly.

Thermostats, like all technology, are becoming more useful and smarter all the time.

What is a Wireless Thermostat?

A wireless thermostat (like the Salus) is a thermostat that is connected to your boiler via wires (the wireless bit refers to the way it’s controlled via the internet). A receiver is connected to your internet router so that there is communication between the receiver and the hub that is connected to the boiler.

A wireless thermostat will still have a traditional wall thermostat control but it isn’t wired to the boiler, it is connected to the boiler via the receiver in your home. Occasionally you will need to change the batteries on your thermostat.

Another benefit of a wireless thermostat is that you can control your home temperature through your smartphone. Just download the appropriate app from the app store and you will be able to change the temperature from your phone and manage the schedule of when your heating is on or off. This allows you to turn the heating on before you get home so it’s nice and warm or turn the heating off after you’ve left home if you forgot to turn it off.

Many wireless thermostats offer additional benefits such as holiday mode, which allows you to turn off your heating for a set amount of time, to frost protection, allowing you to set a minimum temperature for your home before your heating comes on.

A wireless thermostat allows remote connectivity, giving it a massive advantage over traditional thermostats. Wireless thermostats can be added to traditional boiler set-ups, if you want to give yourself added control over your heating.

Why Choose a Wireless Thermostat?

  • Convenience – Change your home’s temperature from anywhere using your smartphone.
  • Energy Efficiency – Set heating schedules that match your routine, reducing wasted energy.
  • Greater Control – Adjust heating on the go, ensuring your home is warm when needed and off when not.

The iT800: A Smarter, More Reliable Wireless Thermostat

Older wireless thermostats provide basic remote control, but the iT800 takes things further with enhanced connectivity, smart home compatibility, and intelligent automation. Suppose you’re looking for a future-proof heating solution. In that case, the iT800 is a great choice for effortless temperature control and energy savings.

I’m Not Sure What Kind of Thermostat I Need

The answer to this question will often depend on the needs you have in your home. If you don’t need anything fancy or you don’t have a smartphone, then the answer is simple – a traditional thermostat will be just fine for you.

You won’t get the savings on your energy bills that you would get a wireless or smart thermostat but you will get a simple mechanism that is easy to operate which won’t stop working if your internet goes down.

If you like the idea of being able to control your heating from your phone and save money by getting your heating to work as and when you need it, then a wireless (or programmable thermostat as they are also known) is the one for you.

Smart Home Technology is increasing in sophistication and application all the time, more and more devices are becoming smart, allowing them to connect to the home automation system and make life easier for owners. With more gadgets there are also more issues, the more connections there are the more chance there is of something dropping out, but the increase in efficiency and quality of life should more than compensate for the risk.

What are the Benefits of the Salus Controls iT800 Wifi Smart Thermostat – IFC?

The Salus Controls iT800 Wifi Smart Thermostat – IFC is the latest addition to the Salus range, offering enhanced control, improved connectivity, and seamless integration with modern smart home systems.

What’s New with the iT800?

  • Smart Home Compatibility – Unlike older Salus models, the iT800 integrates directly with Google Home and Amazon Alexa, allowing you to control your heating with voice commands or through your existing smart home setup.
  • Enhanced Connectivity – The iT800 features improved WiFi stability and a stronger signal range, reducing the risk of disconnections between the thermostat and receiver—a common issue with previous models.
  • Geolocation & Adaptive Scheduling – The thermostat can now use geofencing to detect when you’re near home and adjust your heating automatically. This reduces energy waste and ensures your home is always at the perfect temperature when you arrive.
  • Multi-Room Control – Unlike earlier models that only supported basic scheduling, the iT800 offers zone-based heating, allowing you to set different temperatures for different rooms or areas of your home.
  • User-Friendly Interface & App Upgrades – The Salus Smart Home app has been redesigned for a more intuitive experience, making it easier to create schedules, monitor usage, and adjust settings remotely.

What are the Downsides of a Salus Controls iT800 Wifi Smart Thermostat – IFC?

The downsides of the iT800 include limited functionality when compared to leading smart thermostat brands, but the price tag is also much lower.

A small number of users report having connection issues with the iT800, with the connection between the gateway and the receiver dropping out intermittently. This could have something to do with the thickness of walls or if there is metal blocking the signal or it could be that some of the units have a hardware issue that is hard to diagnose.

The majority of Salus users never experience any issues with the device, you just set it up and leave it be, easily controlling your heating from your phone.

What Features Does a Salus iT800 Have?

The Salus iT800 is a fairly basic programmable thermostat and as such does not have a lot of features, but it has all you need to remotely control your heating and set up schedules based on your needs.

  • Holiday Mode – Allows you to turn your heating off until a set time or date. This is a less sophisticated version of the geofencing found on smart thermostats, which turn themselves off or on based on the proximity of your phone to the device.
  • Scheduling – You can set a 5/2 or a 7-day schedule on your thermostat. If you work 5 days a week, you can set a separate routine for weekdays and weekends. Each day’s timing can be adjusted individually, making bulk changes easier—like when the clocks move forward/back or if your morning schedule changes.
  • Frost Protection – Set a minimum temperature for your heating system to ensure it never drops below a certain level and keep the frost at bay.
  • Internet Controlled – Adjust your settings/temperature remotely using a PC or smartphone.
  • Pre-Synced to Plug and Play – Designed to be easily installed and set up.
  • Geolocation – Your Salus will alert you when you are within a certain distance of your home.

Conclusion

Hopefully, you now have all the information you need to make an informed decision about what thermostat suits your needs best.

Salus Smart Thermostat offers a great way to save money on your heating bills by giving you more control over your heating but it’s also an affordable programmable thermostat.

Unless you have a smart home, you’re a tech buff or there is a specific feature you want from a smart thermostat we think that the Salus Thermostat is a solid choice that will do a fine job of controlling your heating with little confusion or hassle in setting up.
