The ThermoSphere Programmable Thermostat is a thermostat that allows you to program when your electric underfloor heating turns on and off for every day of the week. This automatic schedule for your underfloor heating maximises efficiency and optimises your energy usage.
Available in two colours, white or black, the ThermoSphere Programmable Thermostat features a sleek glass display with a bright LED screen.
This thermostat comes with one external floor sensor probe to install with your electric underfloor heating. You can also purchase an extra sensor probe to install at the same time, but leave disconnected – so that if the first probe should fail there is a backup that can easily be wired in.
The ThermoSphere Programmable Thermostat features 6 heating events (3 on and 3 off) for every day of the week, allowing you to design an efficient, economical heating schedule for your underfloor heating system that fits in with your lifestyle. You can also adjust the temperature manually to boost your underfloor heating output until the next scheduled heating event. There is also a WiFi version of this thermostat that can be controlled and configured via an app on your smartphone.
The ThermoSphere Programmable Thermostat comes with a built in ambient temperate sensor and external floor sensor for accurate temperature measurement. It also features an open window or door sensor that will automatically switch off the underfloor heating when it senses that a door or window is open, to reduce heat loss.
The ThermoSphere Programmable Thermostat also learns how long it takes your floor to heat up, and then optimises the start up time to ensure your room is warm when you want it to be.
You can lock the screen by holding the up and down buttons simultaneously to prevent tampering.
