If the system heat call continues through another time period, the set point will be increased again. This will continue until either the system heat call ends, a maximum of 20 increases has occurred, or the maximum set point has been reached. Once the system heat call has been satisfied the set point will revert back to its calculated setting. This parameter can be changed by the user or the installer. The temperature range of this parameter is 0 to 45F. The default value is 0F. This feature will be active if this parameter is set to anything other than 0F1 Service Service ManualNight Setback Parameters Screen Service Manual Cascade Parameters ScreenCascade Operation 1 Service Service ManualPumps Parameters Screen 0 - 10Vdc BMS Parameters Screen Service ManualModBus Timeout 0-10VdcOperationModBus Timeout 1 ServiceService Manual •BMS Modulation at Minimum Voltage - Determines the modulation rate of the unit or cascade when the BMS input voltage is at or below the setting of the BMS Voltage at Minimum Modulation parameter.
