Heating and district heating controller, equitherm

Max. three control loops in the following combinations:

• Control of a primary heat exchanger or boiler, two regulated and one unregulated heating circuit, and control of the drinking water heating in the secondary circuit

• Weather-dependent buffer tank control with solid fuel boiler and solar circuit control, as well as max. two mixed-heating circuits

• Control of two weather-dependent heating circuits and one drinking water heating with three valves in the primary circuit

• Control of three weather-dependent heating circuits

EQJW246F003: Applications with up to six control loops via expansion modules

Different system models, e.g. for district heating, single-stage boilers, buffer tanks, drinking water heating with solar energy

Weather-dependent supply temperature control based on heating characteristic or 4-point characteristic

To regulate more circuits, multiple controllers can be connected to each other via a device bus
