Manually Overriding The System (Non-programmable)
You have the ability to override the system from the remote sensor. If any button is pressed, the sensor will temporarily take control of the entire system for
four hours. If at any point another button is pressed from that sensor, the four-hour time starts over. If you interact with any other remote sensor, it will start
the timer over, and that sensor will take control of the system.

System Averaging
System Averaging will average all remotes together to provide a more accurate temperature of the entire home. Adjusting
the temperature from any remote will temporarily put that room in control of the system. If the upstairs thermostat reads
80 while the basement reads 70 the system will condition the home to a 75 ambient.

When using remote sensing, this system can be congured four separate ways to maximize comfort for homeowner and
cater to each of their unique lifestyles.
Scheduling
With scheduling the system you can make dierent rooms in control for each part of the day. For homeowners with
predictable schedules, this ensures each room will be the target temperature when scheduled to be used. Making the
kitchen in control in the morning, your home oce during the day, your living room in the evening, and your master
bedroom at night is a great hands-free approach to maximize comfort.

Occupancy Sensing (System Average Mode)
This is an excellent solution for a home with multiple occupants. Each time a remote senses occupancy, it starts an
automatic, internal timer. The system is controlled using the average of the temperatures from only the remotes with
active timers. When a remote’s timer expires, the system removes that remote from the average.

Occupancy Sensing (Last Seen Mode)
This is the perfect solution for homes with a single occupant with less predictable schedules, using the built-in
occupancy sensors moves the comfort around the home without the need for scheduling. As soon as someone
enters a room, it takes control of the system.
