What is the difference between Tempo and the 3iE Thermostat?
Tempo Programmable Thermostat
The 3iE features energy-monitoring functionality which tracks your exact usage, based on your fuel rates, displays your underfloor heating costs. This can help you conserve enery and save money on your heating bills. The Tempo does not have this function.
The design and navigational interfaces also differ. The Tempo features a simple dial to set your heating programme whereas the 3iE features a larger, full colour screen and a more advanced control panel which provides easier management of the heating system.
