17.4 Set manual speed

Pump variant
TPE3, TPE3 D
TPE2, TPE2 D
This menu is only available in the advanced control panel. With
Grundfos GO, you set the speed via the Setpoint menu.
You can set the pump speed in % of the maximum speed. When
you have set the operating mode to Manual, the pump starts
running at the set speed. The speed can then be changed
manually via Grundfos GO or via the advanced control panel.
Factory setting
See section 35. Factory settings.

17.5 "Set user-defined speed"

You can set the motor speed in % of the maximum speed. When
you have set the operating mode to "User-defined speed", the
motor runs at the set speed.

17.6 Control mode

Pump variant
TPE3, TPE3 D
TPE2, TPE2 D
Possible control modes:
• AUTO
ADAPT
• FLOW
ADAPT
• Prop. press. (proportional pressure)
• Const. pressure (constant pressure)
• Const. temp. (constant temperature)
• Con. diff. press. (constant differential pressure)
• Con. diff. temp. (constant differential temperature)
• Const. flow rate (constant flow rate)
• Const. level (constant level)
• Const. other val. (constant other value)
• Const. curve (constant curve).
Set the operating mode to Normal before you enable
a control mode.
You can change the setpoint for all control modes, except
AUTO and FLOW , in the Setpoint submenu under
ADAPT ADAPT
Settings when you have selected the desired control mode.

The AUTO control mode is a form of proportional-pressure
ADAPT
control where the control curves have a fixed origin, H
The AUTO control is developed specifically for heating
ADAPT
systems and we do not recommend that you use it for
air-conditioning and cooling systems.
