Press the UP or DOWN buttons to scroll through additional Cascade Settings. NOTICE Stage Delay 60 sec Minimum Firing Rate Max.
7.0 Cascade 7.5.4 Boiler Enabling Algorithm The Master boiler uses the following algorithm to determine when the next boiler can be enabled: Number of Boilers Firing +1 x Minimum Firing Rate = Individual Boiler Firing Rate Number of Boilers Firing Once the currently fired boilers reach the calculated firing rate, the next boiler can be enabled without affecting the overall cascade firing rate.
7.0 Cascade 7.5.7 CH/DHW Boilers Default: 0 The CH/DHW Boilers setting specifies how many boilers in a Split Cascade System will respond to a domestic hot water call. The CH/DHW Boilers always begins with the Master boiler. The remaining boilers of the Cascade System will only respond to central heating calls. This allows the Cascade System to satisfy both central heating and domestic hot water calls at the same time.
7.0 Cascade 7.5.9 CH Proportional Gain Default: 7 CH Proportional Gain allows the cascade response to be adjusted for a central heating call. CH Proportional Gain has the greatest influence when the system temperature is far away from the setpoint. Press the LEFT or RIGHT buttons to adjust the CH Proportional Gain then press the OK button to store the setting.
7.0 - Cascade To reach the setpoint faster, decrease the CH Integral Gain value by 2. Perform Cascade Autodetection and initiate a central heating call. Observe the cascade response and make further adjustments if necessary. NOTICE Only make adjustments to this setting after consulting ACVTriangle Tube Technical Support. Improper adjustment of CH Integral Gain could lead to temperature fluctuations and erratic cascade operation. 7.5.
7.0 Cascade 7.5.12 DHW Integral Gain Default: 245 DHW Integral Gain allows the cascade response to be adjusted for a domestic hot water call. DHW Integral Gain has the greatest influence when the system temperature is close to the setpoint. Press the LEFT or RIGHT buttons to adjust the DHW Integral Gain then press the OK button to store the setting. • Increase DHW Integral Gain - • The Cascade System will take longer to reach the setpoint, but setpoint overshooting is minimized.
8.0 8.0 Modbus Interface MODBUS INTERFACE The Modbus Interface allows a Building Management System (BMS) to directly connect to the Prestige. A BMS can read information from the boiler to determine its operating state, lockout status, sensor readings, etc. A BMS can also operate the boiler by providing a setpoint.
