District heating, 2x mixed circuit, DHW with heat exchanger (Hy0511)
  • Demand based control of disctict heating station with one primary-side valve
  • Outdoor temperature-compensated flow temperature control for radiators, convectors and low temperature heating circuits
  • Hot water preparation for tank with layer filling and external heat exchanger

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.
Remote energy control
  • Functions according to AGFW guidelines
  • Demand control of setpoint request from downstream control circuits
  • Sliding or fixed maximum limitation of the remote energy return temperature
  • Minimum valve stroke for exact recording of heat volume in low-load operation
  • Interval rinse for temperature recording in the primary return with closed remote energy valve
  • Fixed maximum limitation of the remote energy return temperature during hot water filling
Mixed circuit
  • Time switch for daily, weekly and holiday programs for each heating circuit
  • Minimum/maximum limit of flow temperature
  • Frost protection function
  • Optimisation of switch-on times
  • Pump switching on demand
  • Forced pump running
Hot water control
  • Timer switch with daily and weekly program for tank filling and circulation pump
  • Anti-legionella automatic system
  • Hot water preparation according to the layer filling principle with external heat exchanger
  • Hot water priority circuit, -Conditional priority, -Outdoor temperature-compensated parallel operation, -Priority operation with intermediate heating
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)
  • 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.
