Programmable Low-Voltage Thermostats
Set these thermostats to adjust the temperature at certain times each day. If the power fails, they have battery backup to retain your program.
They control low-voltage HVAC systems. Single-stage thermostats work with systems that have only one speed. Multistage thermostat works with systems that have up to three heating speeds and two cooling speeds.
Thermostats with a daily program function can have an individual program for each day of the week.
Add an optional remote sensor (sold separately) to touchpad thermostats to take temperature reading up to 300 feet from the thermostat.

Wi-Fi Enabled Programmable Low-Voltage Thermostats
Connect to a Wi-Fi network so you can remotely program, monitor, and control the temperature from a computer, tablet, or smart phone. These thermostats control low-voltage, multistage HVAC systems that have up to three heating and cooling speeds. Use them to set an individual program for each day of the week.

Snap-Action Thermostats
Also known as snap discs, these thermostats switch on cooling systems or switch off heating systems when equipment gets too hot. Each thermostat has five temperature options for switch activation; choose the one that best suits your application.
Unlike heat-actuated switches, these thermostats reset automatically, saving you the effort of replacing a melted fusible link. To calculate their reset temperature, subtract their differential temperature from the temperature you set them at. For example, a thermostat set at 100° F with a 20° F differential will reset at 80° F.
Normally open thermostats are also known as low-limit thermostats—they turn on at a set temperature. They’re good for use with fans and blowers.
Normally closed thermostats are also known as high-limit thermostats—they turn off at a set temperature. They’re often used with electric water heaters, stoves, and furnaces.
