Frequently Asked Questions

How do I connect my stat to Wi-Fi?

The Wi-Fi thermostats are controlled through the SWATT app which can be found on the Apple or Android play store. This app allows you to connect your thermostat to your smart device. For detailed instructions or how to connect your thermostat please refer to the installation manual.

What are the benefits of a Wi-Fi thermostat?

The benefits of a Wi-Fi thermostat are that it allows you to control your heating via your smart device rather than on the unit. This means wherever you are, even away from home you can adjust your heating for example turning your heating on when you leave the office so that it's heating when you get home.

How many thermostats can I have on the one app?

The app allows you to connect multiple thermostats all to the one app, up to 32 thermostats on one app. The app allows you to group the thermostats together and control as one or control as individual units eg all bathroom thermostats in one group. The maximum number will be subject to your router and Wi-Fi capabilities.

Can multiple people control the same thermostats from different devices?

Yes, multiple users can be connected to the same thermostats on different devices. This works through all users logging into the app under the same account which will then display all the thermostats on that account.

Can I use the thermostat without the app?

Yes, the touchscreen thermostat provides you with full control over the heating from the physical unit. This means when you are in the room you can adjust the settings on the thermostat if you desire.

Can I control my underfloor heating and towel rail from one controller?

Yes, with our Thermotouch 4.3dC dual control thermostat, you can individually control both your underfloor heating and towel rail from the single controller.

What temperature should I set my underfloor heating at?

Every situation is different however it is recommended to set your underfloor heating to 24°C to begin with. After testing for several days increase or decrease the temperature to find your comfort temperature. Please note a decrease of 1°C may not affect the comfort or warmth of the floor enough to make it noticeable but can help to reduce running costs.

Can I control multiple zones with one controller?

No, each zone that you want to have individual control over needs to have its own separate controller.

What are the rough in or first fix requirements for Underfloor Heating and a Controller?

When roughing in for our Underfloor Heating and the controller, the electrician will first need to bring mains power to the Thermostat location. The electrician will then also need to run two 20mm conduits from the Thermostat position down to the floor, for the Underfloor Heating Cold Tail and for the Floor Sensor. For further information and a visual representation, please view our Conduit Requirements download.

What is the flexible conduit for? Do I need to install it?

We recommend the use of a conduit for the floor sensor so that in the event of a floor sensor failing or the thermostat being upgraded, the floor sensor can be replaced without damaging the floor covering. If this is not possible we recommend installing a second-floor sensor as a spare.

Do I need to purchase a floor sensor?

No, every Thermotouch Thermostat is supplied with a compatible floor sensor, so this does not need to be purchased separately.

What is a floor sensor?

A floor sensor is a small probe that is installed beneath the floor, between two runs of heating cable. This is connected to the Thermostat and gives an accurate reading of the floor temperature.

How long should the floor heating be left on for?

The length of time depends on your lifestyle, the system used and the desired temperature.
