The main purpose of HVAC/R is to manage temperature, humidity, and other parameters in a building. There are numerous devices that are designed to generate heat or cool down the air, but they create a complicated structure that needs to be adequately controlled in order to operate. Thermostats are special mechanisms that monitor environmental conditions in the building and alter them by activating heating and cooling devices. Mega Depot offers a variety of thermostats from such brands as Dwyer Instruments, Morris, NIBCO, Peco, and Pfannenberg. Find and buy the best products on Mega Depot!

Thermostats Products List

Thermostats are special gadgets that will help you monitor the warmth in your building with the help of sensors placed in different rooms. A predetermined value can be established as the desired heat level, and if this device detects that the current temperature is different from the desired value, it activates heaters or AC until the desired environmental conditions are reached. Thermostat sensors may be presented as a collection of gadgets that differ in construction types and materials.

There are three management principles used by these control devices - mechanical, pneumatic, and electrical control. The first type reacts to various heat level changes by affecting mechanical parts and levers, and they are usually placed on or near the heater or cooling unit. The second type affects the HVAC/R system by a collection of tubes filled with air that react to pressure changes (that occur due to variations in temperature). The third type has electrical wires that transfer signals from sensor elements to control panels of HVAC/R. Such thermostats can be presented in digital and analog forms.
