FAQ's

Is the Warmup 7iE suitable for all electric underfloor heating systems?

It is designed for electric underfloor heating and is particularly well suited to systems that need accurate floor temperature control, smart scheduling and app-based access. Always check total load and compatibility with the heating system before installation.

What is the maximum load the 7iE can handle?

The Warmup 7iE has a maximum switching capacity of 16A / 3680W. If the connected heating load is higher than this, a contactor should be used.

Does the Warmup 7iE require a separate hub?

No. It has built-in WiFi and Matter support, so it can integrate with compatible smart home platforms without relying on a proprietary Warmup hub for core operation.

Can I still control the thermostat if the internet goes down?

Yes. The thermostat includes a full-colour touchscreen, allowing manual local control even if your internet connection is unavailable.

What sensors are included with the Warmup 7iE?

The thermostat includes a 3m NTC10K floor sensor and also features built-in air sensing for room temperature control.

Is this a good thermostat for zoning?

Yes. The 7iE is a strong option for room-by-room heating control, especially where you want smarter scheduling, better comfort and more efficient use of electric underfloor heating.

Will this help reduce running costs?

It can help improve efficiency by using scheduling, SmartGeo™ and weather-based adjustments to reduce unnecessary heating time. Real savings depend on insulation levels, room usage, floor build-up and the heating system installed.

What back box depth is recommended?

Warmup recommends a 50mm deep back box, although a 35mm minimum is acceptable.

Is the Warmup 7iE only for floor heating?

It is primarily designed for electric underfloor heating control. If you are comparing controls for other radiant systems, it is worth reviewing the application and control requirements before choosing a thermostat.
