7.1.15OpenTherm

•OpenTherm is the plug & play bus system!

•OpenTherm has developed into a standard in heating technology. Many gas condensing boilers today feature an OpenTherm connection or manufacturers offer an optional OpenTherm interface.

•The OpenTherm bus uses simple bi-directional 2-wire communication between the heat generator and the room controller.

The simple OpenTherm 2-wire bus allows bi-directional communication between the room controller and heat generator, i.e. data exchange occurs in both directions.

In use, the simplicity of the OpenTherm system is key.

The boiler setpoint is transmitted from the SDC controller to the automatic stokers via OpenTherm, and feedback of the boiler actual value occurs from the automatic stokers (in addition to the hot-water actual and outside temperature and fault messages, if appropriate).

Setting in the "Heat Generator" menu, parameter 1, setting 5 (automatically detected when a heat exchanger bus (OpenTherm) is connected (AUTOSET), however).

If the OpenTherm function is active, the boiler minimum limit is automatically set to 5°C.

To use the OpenTherm function, the boiler must have an
