Access the 4iEv03’s intuitive menus via the touchscreen to ensure your floor is always the right temperature.
The 4iEv03 is not just smart, it’s also safe and versatile. Built-in GFCI protection, for use on either 120V or 240V systems, up to 15 Amps and temperature sensing via air or floor sensors, or a combination means you can optimize your environment.
A Wi-Fi version with many industry-leading smart features is also available: see the 4iEv04 here.

- Smart Start means your thermostat learns over time when to turn on the heat
- Full-Color 3.5” touchscreen is customizable and dimmable; it even turns completely off if you like
- Master/Relay mode means the 4iEv03 can control other 4iE’s or stand-alone relays*
- Controls most electric floor heating systems and baseboard heaters, using the included floor or built-in air sensor
- 2 colors, Cloud White [or Onyx Black Discontinued], with beveled chrome edges
- 3 Year Warranty and lifetime 24/7 tech support
- 10 Ft floor sensor included which can be extended 90 Ft on site
*Master/Relay mode requires low voltage wire connection between thermostat(s) and relay(s) and allows the temperature to be sensed at one location only. Used for large areas that require multiple circuits in the same zone; each relay or stat requires a circuit. Built-in 15A can be extended with RL-240-25A and RL-120-25A relays for an additional 25A load switching capability
