Boiler, direct heating/ mixed circuit, DHW (Hy0201)

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

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)
Cooling function - switchover based on outside temperature

Hot water control

Combination

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.
