Nuheat SIGNATURE Thermostat & Control4 Home Automation System

New for 2018…

The Nuheat SIGNATURE floor heating thermostat can now be controlled using the Control4 home automation system (HAS).

The official Nuheat SIGNATURE driver developed by annex4 (a third-party solutions provider) allows homes with the Control4 system to control multiple SIGNATURE thermostats in real time. Now users can make changes from any Nuheat or Control4 interface and get instantaneous feedback across all platforms. With the SIGNATURE and this driver you can:

  • Change the floor heating temperature instantaneously
  • Modify or set the heating schedule
  • Simultaneously turn Away Mode on or off for one or more thermostats (Note: Does not turn the stat completely off or on, but instead toggles between Home and Away modes)

SIGNATURE installs with a simple drag-and-drop method: just enter your Nuheat credentials to get started. The thermostat integrates the annex4 LiNK for easy driver updates, events, and logs.

While the SIGNATURE’s app and web portal make control easy from your phone, tablet or computer, the Control4 integration is the first – and currently the only – connection to a true HAS for any floor heating thermostat.
