Set these thermostats to adjust the temperature at certain times each day. They control low-voltage HVAC systems. You can lock the settings to prevent unwanted or accidental changes, which is helpful in public areas. If the power fails, these thermostats have battery backup to retain your program.
Touchpad thermostats can be used with a remote sensor (sold separately) that takes temperatures up to 300 ft. from the thermostat.
Single-stage thermostats work with systems that have only one speed. Multistage thermostats work 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.

Control, monitor, and program your HVAC system from anywhere. These thermostats connect to a Wi-Fi network, so you can use a computer, tablet, or smartphone to view and adjust settings. You can also lock the settings to prevent accidental changes or tampering in public areas. They 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.
Location-sensing thermostats connect to an app that tracks the location of your mobile device. They can automatically adjust the temperature based on your distance from the thermostat. Use the app to send push notifications for service reminders, unexpected temperature changes, and interruptions to the Wi-Fi connection.
Thermostats with a humidity/temperature sensor also detect motion. Place the remote sensor in a room or enclosure to maintain a consistent climate. To help save energy, they can raise or lower the temperature when no motion is detected.

Control a single heating or cooling device in your enclosure to keep electronics at a safe operating temperature. Clip them on to a DIN rail and connect them to your heater, fan, or air conditioner.
All these thermostats meet American, Canadian, or European safety standards. They have an IP20 rating—to prevent shocks, fingers won’t fit inside. They also meet UL 94 V-0, so they self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping.
Adjustable thermostats let you set the temperature you need. Nonadjustable thermostats have a fixed temperature setting to prevent tampering or accidental changes.
These thermostats keep the air in your enclosure within a set range. Temperature setting is the high end of the range for both heating and cooling thermostats. Heating thermostats are normally closed—when the air in your enclosure reaches the temperature setting, the thermostat will turn the heater off. Cooling thermostats are normally open, so they’ll switch your fan or air conditioner on when the air in your enclosure reaches the temperature setting.
Temperature difference is the difference between the temperature when the thermostat turns your device on and when it turns off. For a heater thermostat with a temperature setting of 50° and an 18° temperature difference, the thermostat will switch your heater on when the temperature goes below 32° and off once the temperature reaches 50°. Thermostats with a lower temperature difference maintain a narrower range of temperatures, but they use more power because they switch on and off more frequently.

Keep electronics in your enclosure from getting too hot or cold with these thermostats that control two devices at once. Clip them to a DIN rail to install.
Nonadjustable thermostats prevent tampering and accidental changes. Adjustable thermostats allow you to set custom temperatures.
Heating and cooling thermostats control heaters and fans or air conditioners. Thermostats with one actuation point, also known as changeover thermostats, switch between heating and cooling so one device is always running. When the temperature in your enclosure gets hotter than the temperature you set, the thermostat will turn on your fan or air conditioner. It goes back to heating once the temperature is reduced by the temperature difference. So for a thermostat with a temperature difference of 9° F, setting it at 60° F means it will heat the enclosure until it reaches 60° F, switch to cooling until it reaches 51° F, and then switch back to heating.
Heating and cooling thermostats with two actuation points control two devices independently. When your enclosure temperature is within the set range, neither device is powered, so they’re more efficient than changeover thermostats. For each device, temperature setting is the high end of the temperature range, and temperature difference is the size of the range. For a thermostat with temperature settings of 59° and 95° F and an 18° F temperature difference, the heater will switch on when your enclosure is colder than 41° F and turn off when it reaches 59° F. The fan or other cooling device will switch on when the temperature goes above 95° F and turn off once the enclosure cools to 77° F.
Cooling thermostats regulate two cooling devices, such as a fan and an air conditioner, for two-stage cooling. Use only one device for cooling in mild temperatures or both for extreme heat. These thermostats switch your equipment on when the enclosure is hotter than the temperature setting. Once the temperature is reduced by the temperature difference, it will switch off. For example, a thermostat set at 77° F for a fan and 140° F for an air conditioner will power both devices when the enclosure is over 140° F. With a temperature difference of 18° F, the air conditioner will switch off when the temperature goes below 122° F. The fan will run until the temperature reaches 59° F, and switch back on if it heats up to 77° F or hotter.
All thermostats meet IP20, which means they’re designed so fingers can’t fit inside and get shocked. They also meet UL 94 V-0, so they self-extinguish within 10 seconds if they catch on fire and won’t spread the fire by dripping. Thermostats that are CE marked or VDE certified meet European safety standards. UL Recognized Component and C-UL Recognized Component thermostats also meet American and Canadian safety standards.

Snap-Action Thermostats
![](/prerenderstable/mvPRE/contents/gfx/imagecache/862/8624n11-@halfx_637581596625950799.png?ver=imagenotfound)
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.

Also known as a two-pipe thermostat, this thermostat uses compressed air for power. Use when electricity is not practical or available for controlling your HVAC system. It is direct action, so as the temperature goes up, the pressure in the system goes up.
Air consumption is measured in standard cubic inches/minute (scim).
The included universal fitting kit consists of a cover, mounting plate, dial stops, screws, tubing reducers, tubing, and mounting hardware. Internal filters are for the air connections and are included.
