| 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. |
|
| Remote energy control |
| • |
Functions according to AGFW guidelines |
| • |
Demand control of setpoint request from downstream control circuits |
| • |
Sliding or fixed maximum limitation of the remote energy return temperature |
| • |
Minimum valve stroke for exact recording of heat volume in low-load operation |
| • |
Interval rinse for temperature recording in the primary return with closed remote energy valve |
| • |
Fixed maximum limitation of the remote energy return temperature during hot water filling |
|
| Heating circuit |
| • |
Time switch for daily, weekly and holiday programs for each heating circuit |
| • |
Minimum/maximum limit of flow temperature |
| • |
Frost protection function |
| • |
Optimisation of switch-on times |
| • |
Pump switching on demand |
| • |
Forced pump running |
|
| Hot water control |
| • |
Timer switch with daily and weekly program for tank filling and circulation pump |
| • |
Anti-legionella automatic system |
| • |
Hot water priority circuit, -Conditional priority, -Priority operation with intermediate heating |
|
| 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) |
| • |
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. |
