Boiler, direct heating circuit, DHW

Outdoor temperature-compensated boiler temperature control for one direct heating circuit and hot water preparation system
Can be used as an independent controller or in conjunction with additional SDC controllers
Burner control for demand-based control of all boiler types
Unmixed heating 1 circuit
Domestic Hot Water 1 pump
Boiler 1-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 one-level burner
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 circuit, with room tie-in as necessary
Min./max. limiting of flow temperature
Hot water control
Time switch with daily and weekly program for one-level burner
Anti-legionella automatic system
Hot water priority 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
