The charts below show possible control modes of TPE
Series 1000 pumps in different applications.
Control options
Communication with TPE Series 1000 pumps is
possible via:
• a central building management system
• a remote control (Grundfos R100)
• a control panel.
The purpose of controlling a TPE Series 1000 pumps
is to monitor and control the pressure, temperature,
flow and liquid level of the system.
For further information on control options of TPE
pumps, see page 20.
