2x Boiler 2 stages, 3x mixed circuit, DHW (Hy0305)
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.
Domestic Hot Water
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 series controller for one or two-stage boilers
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
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 option of up to five freely-selectable SMILE controllers
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
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.
