Solid fuel boiler, buffer tank, mixed circuit, DHW, solar circuits
| • |
Outdoor temperature-compensated flow temperature control for radiators, convectors or low temperature heating circuits. Integrated differential temperature control for controlling a solar controller. Operation of a solid fuel boiler with constant return temperature control for optimum tank protection. Hot water priority circuit. |

| 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. |
|
| Solid fuel boiler |
| • |
The solid fuel boiler is protected against corrosion and "shining soot", according to its boiler temperature using constant return temperature control. The sensor (PF) works as a joint flow sensor for the buffer tank and the solid fuel boiler. |
|
| 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 mixed circuit/direct heating circuit, as required with room tie-in |
| • |
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 |
|
| Solar control |
| • |
The temperatures of the collector (KVLF) and the hot water tank (VE2) are compared. The control unit switches the solar pump on when the collector sensor detects a higher temperature than the tank sensor. The solar system is used to fill the hot water tank and the buffer tank. |
| • |
Solar energy is used to fill the hot water tank and the buffer tank. |
|
| 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. |
