80 Series® Classic Universal Thermostats for
Single Stage, Multi-Stage, Heat Pump and Truck Stock Use.
We offer the best-selling digital thermostat by combining a single stage, multi-stage and heat pump into one universal
thermostat. And better yet we’ve enhanced it with styling and features specially designed for all systems. It offers
more control, more convenience and more value than the competition. And it’s backed with the reputation of
White-Rodgers — pioneers in home comfort since 1937.
More Accuracy and Control. If you’re in the
process of upgrading a multi-stage, heat
pump or single stage system, don’t forget
the “brain” for your new system…your
thermostat. Our White-Rodgers 80 Series®
can maintain a set temperature to within
one degree. Plus, there’s a permanent
memory that saves all programs and
settings during a power loss.
Comfort and Convenience with Versatility.
The programmable models deliver perfect
comfort, as they automatically change to
the temperature you selected for wake-up,
during the day, evening hours and while
you sleep. You can also configure them
with minimum and maximum temperature
range for cooling or heating. The lighted
display makes for clearer low-light viewing.
Non-Programmable
Maximum Energy Savings. Program heating
and cooling times to cut energy use, not
comfort. You can save up to 33% in energy
costs, depending on your home’s location,
climate and program selections.
Now you can have it all…energy savings, with
comfort and convenience! See the back to
find out how this best-seller gives you more
of what you want in a universal thermostat.
