2x Boiler 2 stages, 3x mixed circuit, DHW
| • |
Boiler series control for two boilers (two-level) and three mixed circuit controllers along with one hot water controller |
| • |
The correct function of boiler series control depends on the appropriate pairing of the controller and hydraulic system. Therefore the consumer circuits should be decoupled from the two boilers using a hydraulic by-pass. |
| • |
Note: System no. 305 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. |
|
| Boiler control |
| • |
Boiler series controller for one or two-level burners |
| • |
Constant minimum limit of boiler temperature |
| • |
Maximum limitation of boiler temperature |
| • |
Minimum burner switch-on and switch-off times |
| • |
Operating hours recording for each burner level |
| • |
Replacement of the pilot boiler, depending on time and external temperature |
| • |
Blocking of next boiler, depending on external temperature |
|
| 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. limiting of flow temperature |
|
| 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 |
|
| 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. |
