2x Boiler 2 stages, 3x mixed circuit, DHW

• 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.

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
• Boiler series controller for one or two-level burners
• 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
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. 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
• 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.
