Heating system with a buffer tank (Hy0406)

Heating system with a buffer tank (Hy0406)

The buffer tank is loaded by an external heat source (solid fuel boiler etc.). The controller controls a mixing loop for radiators, convectors or low temperature heating circuits. A constant temperature control is also possible. Domestic hot water control and the control of the circulation pump are also handled by the controller.

  • Note: System no 406 means that certain parameters must be set for this application to function

  • Functions
  • The basic functions are contained in an indestructible program.
  • All the parameters are predefined with sensible basic settings and allow individual adjustments as necessary. PCs are not required for this.
  • All the relay outputs can be tested manually.
  • Heating circuit
  • Time switch for daily, weekly and holiday programs for each heating circuit
  • Optimisation of switch-on times
  • Caretaker function, frost protection function
  • Outdoor temperature-compensated mixed circuit/direct heating circuit, as required with room temperature compensation
  • Hot water control
  • Time switch for daily, weekly and holiday program
  • Anti-legionella automatic system
  • Hot water priority circuit or parallel operation with heating supply
  • Circulation pump control with different control strategies
  • Combination
  • Combination option of up to five freely-selectable SMILE controllers
  • Communication
  • Communication takes place over the system bus without additional interfaces
  • Distance (max. 100 m)
  • All the data required for the control system is communicated
  • Remote operation with the wall modules SDW.. also takes place using the system bus
  • Fault message
  • If the required temperatures cannot be achieved within a reasonable time, or sensors interrupt or short-out, then the controller will generate a fault message.
