Frequently Asked Questions

How does a thermostat work?

Thermostats work by controlling the flow of hot or cold air and maintaining a set temperature. They operate on thermostat sensors, which sense the room temperature. For more information, read this article on how thermostats work.

How do I replace a thermostat?

  1. Turn off the HVAC control panel.
  2. Dislodge the old thermostat cover.
  3. Disconnect the wires of the old thermostat.
  4. Remove the old thermostat.
  5. Install the base of the new thermostat.
  6. Connect the thermostat’s wires.
  7. Mount the new thermostat, along with the thermostat cover, on its base.

What temperature should I set my thermostat in winter?

According to the U.S. Department of Energy, the optimal temperature when setting a thermostat is 68 degrees Fahrenheit.

How do I tell if a thermostat is bad?

Some of the signs that tell if a thermostat is not working include:
  • It can’t turn on or off the HVAC system.
  • It can’t detect the room temperature.
  • It is unresponsive.

What's the difference between hold and run in thermostats?

In programmable thermostats, smart thermostats, and wireless thermostats, pressing the hold button overrides the programmed temperature. The run button allows these digital thermostats to return to their programmed temperature and schedule.


Thermostats are vital to keeping workspaces, residential spaces, industrial facilities, commercial facilities, and many more warm and comfortable. These are the devices that allow people in the facility to control temperature levels. Simply establish a setpoint, and the thermostat would work to sense the temperature inside a space and act toward maintaining the set temperature.

Engineer Warehouse offers a variety of thermostats that can work with a variety of heaters and heating systems. You’ll also find thermostats that have motion sensors, which automatically turn heaters on when people walk into a space. Motion sensors also detect when people leave the space or residence, and the connected thermostat will automatically put the heater on sleep mode in order to save on electricity costs.

All thermostats in the catalog below are designed to be easy to use and install, as well as durable and long-lasting. Set up heating equipment with little to no hassle by choosing the best thermostat for your system below.
