Thermostats  
Step 1: Identify your heating/cooling system  
IMPORTANT: Thermostats are designed to work with specific  
heating/cooling systems, so it’s essential that you know your system  
type to avoid purchasing the wrong style.  
What To Look For  
All thermostats share one common feature — a way to set the temperature. After that, every  
thermostat is different in terms of accuracy, reliability, number of features, display size and  
more. Here are a few features you should consider when choosing your thermostat.  
Be Confident With Honeywell  
Honeywell has been inventing and perfecting thermostats  
since 1885 and is the number one choice of homeowners  
and contractors. You can count on Honeywell products for  
superior design, engineering and efficiency.  
Central Heat or Central Heat & Air — The most common  
system. Can be 24V gas or oil, hot water or electric.  
Heat Pump — Heating and air conditioning combined into  
one unit. Can be single- or multi-stage.

electric baseboards and radiant ceilings.  
Menu-Driven Programming. Some  
programmable thermostats can be  
difficult to program, but menu-driven  
programming guides you through the  
process much like using an ATM.  
4 Programmable Periods Per Day.  
Honeywell programmable thermo-  
stats allow settings for wake, leave,  
return and sleep to provide you  
with a full day of energy savings.  
Automatically determines if your home  
needs heating or cooling to provide maxi-  
mum comfort.

at different times of the day and night, then forget about it —  
the thermostat does the work. Best for people on the go or  
those seeking the most efficient energy savings.  
An easy-to-view dial or a backlit  
screen makes using the thermostat  
a pleasure. Many Honeywell  
models show both the set and  
current temperature, and some  
models also display the current time.  
Precise Temperature Control.  
Industry leading +/-1º accuracy  
maintains comfort.  
How To Select The  
Right Honeywell  
Thermostat For  
See Step 3 for different programmable thermostat options.  
Digital Non-Programmable — Non-programmable thermostat with a  
digital readout. Best for people who prefer manually  
controlled settings with the convenience of an easy-to-read  
LCD display.  
Energy Savings.  
Save up to 33% on energy costs*  
with a programmable thermostat  
Permanent Day and Time. All  
programming information is saved  
in the event of a power outage.  
Mechanical/Manual — Control the temperature setting manually. Best  
for people who are home often and prefer a fixed temperature.
