The 5 Best Honeywell Multi-Zone Thermostat Reviews

First, do you know what a thermostat is? Maybe your answer is yes. It could even be no. To define it clearly; you should have the aspect of heat in your mind. The name thermostat is from the word thermal, meaning heat. A thermostat is a device that senses the temperature of a particular system and maintains it at the desired point. The components help in appliances that heat or cool at set temperature standards. Most machines utilize Honeywell multi-zone thermostats that are very effective.

Machines that use thermostats include water heaters, refrigerators, ovens, incubators, air conditioners, and many other essential types of equipment’s in hospitals and factories. Such devices are in a class by the name Thermostatically Controlled Loads (TCLs). According to statistics, the devices consume 50% of the total electricity in the United States of America.

In this article, we are going to base our discussion on the best smart thermostat for multiple zones. We are going to pick the best five according to our research and give you a detailed review of how they work. By the time you finish reading this article, you will have made up your mind on the best Honeywell thermostat to have in your new machine.

How do Thermostats work?

Honeywell Multi-Zone Thermostat

As we mentioned earlier, a thermostat works to maintain temperatures at set standards. How does the component achieve that? Thermostats utilize the aspect of expansion and contraction. Matter expands when heated and contracts when cooled. Some parts expand or contract to switch electric circuits on or off. We have three types of thermostats. They include bimetallic strips, gas-filled bellows, and wax thermostats.

Bimetallic strips

Thermostats that use bimetallic pieces are pioneers in the industry. The thermostat comprises two metallic strips that act like electrical circuit bridges. With this connected to your heating system, the strips connect and disconnect upon reaching the set temperatures.

In order to maintain the required temperatures, the strip expands more and bends to break the circuit. Temperatures start to drop and the piece cools. At a certain point, the strip flattens and closes the circuit, thus initiating another heating process. The circle ensures that temperatures remain at the right levels.

Gas-filled bellows

Gas-filled bellows are more responsive as compared to the bimetallic strips thermostats. Bimetallic pieces take too long to cool or heat. Gas-filled bellows have two metal discs that have small ridges on their large surface area. There is gas in between them.

When the gas heats up, it pushes the two discs apart, thus disconnecting the circuit. As the gas starts to cool, it contracts. The two discs come together, thus completing the connection. The device begins heating again, thus creating a continuous temperature condition.

Wax thermostats

Wax thermostats are ordinary in car engines. They use the same principle of cooling and heating for expansion and contraction. The component has wax-sealed inside a chamber. When the wax is heated, it changes into liquid and increases in size.

It exerts pressure on a particular rod that disconnects the electric current. A cooling process starts until a certain level when the rod completes the electrical circuit again to begin heating. This cycle ensures consistent temperatures during the mixing of cold and hot water in engines.
