6.3.4 Max. Speed
The maximum speed of the pump is specified here. During the setting the pump runs at the specified speed and the flow rate can be determined.
Settings range: 70% to 100% / Default setting: 100%
CAUTION
The indicated percentages are guide values that may vary to a greater or lesser extent depending on the system, pump and pump
stage.
6.3.5 Min. Speed
The minimum speed of the pump at relay R1 is specified here. During the setting the pump runs at the specified speed and the flow rate can be
determined.
Settings range: (Speed from “J.14.6. - Speed when “On”” on page 53) to max. speed -5% / Default setting: 30%
CAUTION
The indicated percentages are guide values that may vary to a greater or lesser extent depending on the system, pump and pump
stage.. 100% is the maximum possible voltage/ frequency of the controller.
6.3.6 Setpoint
This value is the control setpoint for Mode 3 (see “6.3.1. - Modes” on page 31). If the value at the collector sensor drops below this, the speed is
reduced. If it rises above this, the speed is increased.
Settings range: 0° to 90°C (32°F to 194°F) / Default setting: 60°C (140°F)
