Display of flow rate
l/h
Flow rate
Display range: depending on the sensor type used
Indicates the current flow rate at the VFD flow rate sensor.
The display range depends on the sensor type previously selected.
Display of current pump speed
n %, n1 %, n2 %
Current pump speed
Display range: 30 ... 100 %
Indicates the current pump speed of the corresponding pump.
• n % : Current pump speed (1-pump system)
• n1 % : Current pump speed pump 1
• n2 % : Current pump speed pump 2
kWh/MWh
Heat quantity in kWh / MWh
Display channel
Indicates the energy gained in heat quantity – only available if heat quantity meas-
urement (OHQM) is activated.
The heat quantity measurement can be carried out in 2 different ways (see page
62): with a fixed flow rate value or with a VFD Grundfos Direct Sensor™. It is
shown in kWh in the channel kWh and in MWh in the channel MWh. The overall
heat quantity results from the sum of both values.
The accumulated heat quantity can be set back to zero. As soon as one of the dis-
play channels of the heat quantity is selected, the symbol Ⓢ is displayed.

In order to finish the reset process, press button 3.
In order to interrupt the reset process, do not press any button for about 5 s. The
display returns to the display mode.
CDIS
Countdown monitoring period
Display range: 0 ... 30:0 ... 24 (dd:hh)
If the thermal disinfection option (OTD) is activated and the monitoring period
is in progress, the remaining time is displayed as CDIS (in hours and minutes),
counting backwards.
SDIS
Display of starting time
Display range: 00:00 ... 24:00 (hh:mm)
If the thermal disinfection option (OTD) is activated and a starting delay time has
been adjusted, the adjusted starting time is displayed as SDIS (flashing).
DDIS
Display of heating period
Display range: 00:00 ... 24:00 (hh:mm)
If the thermal disinfection option (OTD) is activated and the heating period is in
progress, the remaining time is displayed as CDIS (in hours and minutes), counting
backwards.
