How does an analog thermostat work?
Most analog thermostats work using a bimetallic strip. Two different pieces of metal expand and contract based on the temperature. Like a light switch, as the strip moves it will open or close the contact to turn the HVAC on or off.

An electromechanical thermostat typically contains either a bi-metal coil or a metal strip. When the temperature changes, this coil or strip will move, causing a vial containing mercury to tip to one side. The mercury flows to one end of the vial, signaling that the heating or cooling needs to be turned on.
Analog thermostats are fairly accurate but limited in their abilities. They are not programmable and have no internal computer to improve efficiency. Why Are Non-Analog Thermostats Better? Modern thermostats have electronic parts that enable them to work more efficiently than analog types.

Some manual thermostats note a range of temperatures on the top and bottom of a dial. The top range is used to indicate the temperature at which the thermostat is set, while the bottom range represents the actual temperature of the area surrounding the thermostat.
It is possible to replace your old thermostat yourself, but you'll need some basic electrical knowledge and have to carefully follow the instructions to do it properly and safely.
There are four basic types of modern thermostats: Non-programmable, programmable, Wi-Fi and smart. The further you get down the list of the thermostats discussed below, the more expensive they become. However, energy efficiency increases with each thermostat.
Press the "System" button to put the thermostat in Heat, Cool or Off mode. To change the setting, push the button again. The screen will display the setting you've selected. On the right side of the display, the up and down arrow buttons operate the temperature settings.
Typically, the "hot" wires, or the wires that provide power to the unit, are the heating and cooling wires, labeled Rc and Rh respectively. They provide the source of 24V power that comes into the main HVAC control board itself.
Can I replace an analog thermostat with digital?
Replacing your analog thermostat with a digital one is a great way to save on your heating bill since digital thermostats are able to control heat more precisely. GNH can provide you with everything you need for installing a digital thermostat!
Manual (Analog) Thermostats
It is the recommendation of most heating and cooling professionals that if you currently have a manual thermostat and are looking to replace it, that you consider upgrading to a programmable model instead of simply repurchasing another manual.
Analog thermostats are the most basic kinds of thermostats and they are also the least expensive.
In most cases, the thermostat will produce a small clicking sound when the changes are made, then the heating or cooling equipment will start. If this clicking sound doesn't occur, or if the system doesn't come on shortly after the changes are made, the thermostat may need replacing.
