32 The table below shows the suggested controller settings: * T i = 100 seconds (factory setting). 1. Heating systems are systems in which an increase in pump performance will result in a rise in temperature at the sensor. 2. Cooling systems are systems in which an increase in pump performance will result in a drop in temperature at the sensor. L 1 = Distance in [m] between pump and sensor. L 2 = Distance in [m

34 Dry running When this function is selected, lack of inlet pressure or water shortage can be detected. This requires the use of an accessory, such as: • a Grundfos Liqtec ® dry-running switch • a pressure switch installed on the suction side of a pump • a float switch installed on the suction side of a pump. When lack of inlet pressure or water shortage (Dry running) is detected, the pump will be stopped. The pump cannot restart as long as the input is activated. Restarts m
