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 one level burner |
|
Heating circuit |
• |
Time switch for daily, weekly and holiday programs for 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 hot water filling pump |
• |
Anti-legionella automatic system |
• |
Hot water priority circuit |
• |
Outdoor temperature-compensated parallel operation only in mixed circuit |
|
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. |
• |
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. |
