OpenTherm thermostat

As a professional thermostat manufacturer, we've been working on developing smart thermostats that not only make your life easier, but also help you save money, using a variety of strategies, including turning off the heat when you're out and turning it off early Boiler so as not to overuse the set temperature. However, if you don't use OpenTherm, you may not get the full power savings you deserve.

Why should you (start to) use OpenTherm certified boilers and thermostats?

In traditional heating systems, a simple relay is used to turn the boiler on or off. When the boiler turns on, it heats the water to a preset temperature until the thermostat tells it to turn off.

But usually when your radiator is fully turned on to heat, it often exceeds the temperature you set. As a result, the thermostat waits until the temperature drops, then turns the boiler on to its maximum gear again. The average temperature you achieve may be correct, but you will end up over and under the levels you set, which is not ideal.

This cycle repeats. Efficiency and control are gone.

OpenTherm, as the name suggests, is an open standard digital interface for modern boilers. With OpenTherm, you get a digital interface to your boiler, allowing your smart thermostat to change the temperature of the water used for heating. This is called modulation.

Since most smart thermostats know how long it takes your home to heat up, they can measure the amount of heat needed to warm your home. From this, they can set the boiler to the most efficient water temperature to achieve their goals. In many cases, the thermostat may set your water temperature to a lower level, using a longer heating time to reach the set temperature. With modern condensing boilers, running longer at lower temperatures can be more efficient and save you more energy.

Once a certain temperature is reached, OpenTherm may lower the water temperature further to balance the natural heat loss through your home's walls, windows, doors and roof.

Importantly, using OpenTherm means the boiler uses only the energy it needs to provide the heat it needs at the time to save money.

About our OpenTherm products

This is a sophisticated room thermostat which provides modulating control of OpenTherm equipped condensing gas boilers. The thermostat is fully compliant with the OpenTherm communications protocol including low load regulation and domestic hot water keep hot feature now in common use in many combination boilers.

As updated products, we newly add wifi control functions, users will easily understand and control the room temperature & domestic hot water situation from APP. What’s more, when boiler not working, user can checking OpenTherm 127 items information from app list, or share the device with maintenance worker to find our issue without going to users home
