  • Page 31: Start-Up Optimization (Early Heat-Up)

    Start-up optimization (early heat-up) Start-up optimization ensures that the boiler is heated before the normal mode commences (based on the room and outdoor temperatures). This ensures that the room setpoint temperature is achieved before the normal mode begins. Minimum and maximum temperatures can be set for the heat-up period.
  • Page 32: Shutdown During Economy And Holiday Mode

    Light Cascade Control heating curve The primary function of the Viessmann Cascade Control is to control the “cascading” or staging of up to four Vitodens 200, WB2-44/60 boilers. It does this by communicating with each individual Vitodens boiler control via the KM-BUS communication module.
  • Page 33: Anatomy Of The Cascade Control Heating Curve

    Anatomy of the Cascade Control heating curve Setting the starting point and ending point establishes the sloped line to calculate supply temperature based on outdoor temperature. The WWSD point is determined by the Outside Temperature Fixed Point. This point moves left/right on the grid to allow the user to select a specific outdoor temperature. The supply temperature that the Cascade Control calculates when emerging out of WWSD is determined by the Flow Temperature Fixed Point.

  • Page 40: Cascade Curvature

    Cascade curvature Unlike the conventional 1.0 curvature and its linear relationship between outdoor and supply temperature, the Cascade Control allows a curvature setting to be programmed. This modifies the linear relationship from a straight line into an arc. The arc runs from the starting (anchor) point to the end point that has been programmed into the control during set-up.

    Nominal value (multiple-boiler control unit) In most cases this value corresponds to the set room temperature in normal mode. Outsidetemp fixed point 20ºC With radiator systems, this value generally corresponds to the low end temperature.

  • Page 43: Multiple-Boiler Control Unit

    Multiple-boiler control unit The modulating cascade control communicates with the boilers via the KM-BUS interface. It calculates the required supply temperature using an outdoor reset control unit. Start-up and shutdown of individual boilers Depending on the heat demand, individual boilers are started or shut down. A boiler is started up if: H the required heat load is higher than the total output of all boilers which are currently operating.
  • Page 44: Automatic Change Of Start-Up Sequence

    Automatic change of start-up sequence Condition: ”Auto sequence change Yes” must be configured (see page 27). Once a week the control unit changes the sequence in which the boilers are started up and shut down (based on the operating hours of each boiler). The boiler which has run the fewest hours is the first to be started, fol- lowed by the boiler with the second lowest number of hours run.
  • Page 45: Safety Functions

    Safety functions Function monitoring with supply temperature reading Proper functioning of the heating system is monitored by comparing the required and the actual supply temper- atures. A fault message is displayed if, within an adjustable period, the supply temperature does not reach the required value less the adjustable tolerated temperature deviation.
  • Page 46: Pump Seizure Protection

    Pump seizure protection Condition: ”Pump seizure protection Yes” must be configured (see page 27). Between 12:00 and 12:05 hrs daily, the pump will be started to prevent it from seizing up. Hour counters and start-up counters The hours and start-up counters store the number of operating hours and the number of start-ups of the boilers and heating system pumps (if installed), which are regulated by the control unit.
