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.

Kuala Lumpur, Malaysia – September 12, 2025 – SASWELL showed off its range of smart HVAC controls at ENGINEER & MARVEX 2025, a big air-conditioning, refrigeration, and ventilation show in Southeast Asia. Industry people, partners, and visitors from all over seemed pretty interested.

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.

I wanted to take a few minutes to chat with you about something that I’m really excited about—SASWELL’s upcoming participation in the 2024 Malaysia International Air Conditioning, Refrigeration, and Ventilation Exhibition (ENGINEER & MARVEX). As someone who's been in the HVAC industry for over 20 years, I’ve seen how the technology has evolved, but what we’re showcasing this year really feels like a big leap forward. So, I’m here to share why I think this could matter to you, and how our solutions might just make your life easier, more efficient, and even more sustainable.

As someone who's spent over 20 years in the HVAC industry, I’ve seen just about everything when it comes to home heating, cooling, and energy management. From the old dial thermostats to today’s smart home systems, the evolution has been nothing short of incredible. But what I’m about to share with you goes beyond just technology—it’s about how you can actually *feel* the difference in your daily life, and save a little (or a lot) along the way.
