Touchscreen Thermostat
Effortless, efficient
temperature control

You want to enhance your home comfort, but you also want to control
your energy costs. Fortunately, the ComfortSense™5000 Series touchscreen
thermostat makes it easy to do both. Menu-driven programming screens allow
you to customize settings with little effort. And advanced logic responds to
your choices and schedule, with minimal temperature swings.
THE EASY WAY TO CONTROL YOUR
HOME ENERGY COSTS AND COMFORT
The ComfortSense 5000 touchscreen thermostat allows you to fine-tune
heating and cooling temperatures according to your specific needs—quickly
and easily. Flexible in use and application, the thermostat mounts directly
to a wall, but can easily be removed for armchair programming.
A simple touch of the menu screen gives you the flexibility to customize a
temperature schedule for every day of the week. Another touch saves your
settings, so you relax in comfort and save money on your utility bills.
