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 |

 |
| 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. |
|
| 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 |
| • |
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. |
