Boiler 2 stages, direct heating/ mixed circuit, DHW

Outdoor temperature-compensated flow temperature control for radiators, convectors and low temperature heating circuits (e.g. underfloor heating) via mixed circuit.
Usable as an independent controller or as an expansion controller in conjunction with other SMILE controllers, heating circuit or other remote heating controllers
Burner control for demand-based control of all boiler types
Unmixed heating 1 circuit
Mixed heating 1 circuit
Domestic Hot Water 1 pump
Boiler 2-stage
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.
Boiler control
Sliding boiler temperature control for two-level burner
One-level burner also possible, if Hydraulics 0201 is set on commissioning
Indirect boiler return control through consumer control
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 heating circuits, with room tie-in as necessary
Min./max. limitation of flow temperature, max. limitation of the heating circuit return temperature (only possible mixed circuit and not in direct heating circuit)
Hot water control
Time switch with daily and weekly program for hot water filling pump
Anti-legionella automatic system
Hot water priority circuit
Outdoor temperature-compensated parallel operation only in mixed circuit
Combination option of up to five freely-selectable SMILE controllers
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.
Application for Smile digital controller
Microprocessor controller for heating circuit, boiler and hot water control
