COMFORT STARTS WITH CONTROL
One system. Different spaces. Control where it matters.
Manage comfort throughout your home, Explorer Portable lets you move control from room to room, ensuring comfort exactly where it matters, without being locked to the wall.
Daytime
comfort
Keep your main living spaces such as the living-room, home office and kitchen comfortable throughout the day.
Nightime
comfort
At night, press any button on the upstairs thermostat to make it the active control, or create a schedule to automatically prioritize upstairs comfort for a better night’s sleep.
How it Works
An innovative wireless control system.
Explorer Portable consists of a wireless thermostat and a compact base station. The thermostat goes where you want control, while the base station can be installed in place of an existing wall-mounted thermostat or at the HVAC equipment to connect and manage the system.
EXPLORER®PORTABLE
Thermostat
T3951RF: A wireless, battery-powered thermostat you can place wherever comfort is needed.
EXPLORER®PORTABLE
Base Station
T3951B: Installed at the HVAC equipment or in a standard wall location, the base station connects and manages the system.
Control up to 6 portable thermostats
all connected through a single Base Station.
Built for challenging installs
No wire. No Drywall repair. No compromise
Thermostat in the Wrong Spot
Two Floors, One Thermostat
Difficult Wire Runs
Adding Zones without New Wiring
Thermostat in the Wrong Spot
Sometimes the thermostat is installed in an inappropriate location, such as a hallway.
In this case, the Explorer Portable replaces the existing hallway thermostat with a wireless base station that communicates with up to 6 portable thermostats to sense temperature and control comfort where it matters most.
Two Floors, One Thermostat
Using two portable thermostats linked to a single base station, Explorer Portable makes it easy to sense temperature and maintain comfort control upstairs or downstairs throughout the day.
Switch active control with the press of a button or automatically through a schedule, without additional wiring or system changes.
Difficult Wire Runs
Explorer Portable wirelessly links the base station and portable thermostats, bringing comfort control to additions, renovated rooms, and hard-to-wire spaces.
Without opening walls or running new thermostat wire.
Adding Zones without New Wiring
Each zone uses its own wireless base station, allowing portable thermostats to communicate with an existing zoning panel without opening walls or running thermostat wire.
Fully wireless system, no thermostat wiring required
