Heating and district heating controller, equitherm

How energy efficiency is improved

Control of max. three control loops depending on the heat requirement or time programme. The control enables the system to be adjusted to the individual requirements of the user, and also to be switched off temporarily if required


Vlastnosti

  • 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

  • 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

  • Convenient operation with state-of-the-art operating concept (turn and press) and large graphical display

  • Convenient weekly and annual switching programmes with optimisation of switching times

  • Automatic summertime/wintertime change-over

  • Min./max. limitation of supply temperature and max. limitation of return temperature

  • Frost-protection facility and anti-jamming function for valve and pump

  • Floor-drying function

  • Function for protecting against legionellae

  • Room temperature switching using room-temperature sensors

  • Ni/PT1000 inputs for the outside, supply, drinking water, return flow and room temperature

  • Relay outputs with varistor suppression for activating control units and pumps

  • Manual mode

  • Logbook

  • 0…10 V input for external requirement or outdoor temperature signal

  • 0…10 V output for continuous control for control loop RK1 or signal for external requirement

  • Binary inputs for fault signals or external requirement processing

  • Interface for various accessories such as modem, gateway, data storage module etc.
