Discover why the 4-inch color screen is becoming the industry’s sweet spot. We analyze the shift to deep customization, efficient interaction, and the supply chain maturity driving this HVAC standard.

HVAC systems are classified as either self-contained unit packages or as central systems. Unit package describes a single unit that converts a primary energy source (electricity or gas) and provides final heating and cooling to the space to be conditioned. Examples of self-contained unit packages are rooftop HVAC systems, air conditioning units for rooms, and air-to-air heat pumps.

Remember, this is for electric water heaters

The majority of modern heating/cooling/heat pump thermostats operate on low voltage (typically 24 volts AC) control circuits. The source of the 24 volt AC power is a control transformer installed as part of the heating/cooling equipment. The advantage of the low voltage control system is the ability to operate multiple electro mechanical switching devices such as relays, contactors, and sequencers using inherently safe voltage and current levels. Built into the thermostat is a provision for enhanced temperature control using anticipation. A heat anticipator generates a small amount of additional heat to the sensing element while the heating appliance is operating. This opens the heating contacts slightly early to prevent the space temperature from greatly overshooting the thermostat setting. A mechanical heat anticipator is generally adjustable and should be set to the current flowing in the heating control circuit when the system is operating. A cooling anticipator generates a small amount of additional heat to the sensing element while the cooling appliance is not operating. This causes the contacts to energize the cooling equipment slightly early, preventing the space temperature from climbing excessively. Cooling anticipators are generally non-adjustable.

In the USA, about 90% of homes are powered by a central heating/cooling system like a central furnace or a boiler or a heat pump based system. We write about boiler thermostats in this guide, which are thermostats for controlling central boiler units. A boiler is basically a specially designed water heater – which distributes heat through hot water, while systems like a central furnace distribute heat through the warm air. Water is heated in a special chamber of the boiler (which is usually powered by gas or fuel oil) and is then distributed to different rooms of the home via radiators or other heat distribution systems installed. A boiler thermostat helps in controlling the boiler operation, thus maintaining a proper set temperature inside the home.

Electric floor heating systems are becoming more popular because they're cozy and save on energy. If you want to make the most of yours, picking the right thermostat is key. In 2025, touchscreen thermostats are the top choice for controlling electric underfloor heating.

Have you ever walked into a room and felt uncomfortable, either too hot or too cold? Chances are, the room is not equipped with a fan coil therthermostat. Fan coil thermostats are a great way to regulate the temperature of a room quickly and accurately. They can be used in residential, commercial, or industrial settings and provide an energy-efficient solution to climate control. In this blog post, we will explore what a fan coil thermostat is, how it works, and some of the benefits associated with using one in your home or business.
