OpenTherm Development for Smart Heating
Heating is getting smarter. End users want to be able to programme smart thermostats easily and expect them to detect presence. Consumers also demand thermostats that understand their preferences, to give them greater control over:
• Electric central heating | Hot water cylinders
• Gas boilers | Combi boilers | Conventional boilers | Modulating boilers
• Storage heaters | Warm air systems
OpenTherm is a low power communications system which can use existing thermostat wiring (and can also used for weather compensation) allowing condensing boilers to reach their maximum efficiency. OpenTherm connects gas central heating (condensing) boilers with room thermostats. Using this technology with compatible boilers, heating control manufacturers can now move from a basic “dumb” ON/OFF to TPI room thermostat.
OpenTherm-based smart controls provide more precise control of room temperature and hot water. The smart temperature controller delivers major increases in efficiency of central heating systems, especially with renewable heating devices such as heat pumps. With OpenTherm interfaces, the system can control its output temperature in a smart way, recognising how quickly the room reaches temperature, enabling a reduction in water temperature from the heat source.
