100% is the maximum possible voltage/frequency of the controller.
The maximum speed of the pump is specified here.
Setting range: 15-100% /Default setting: 100%
The minimum speed of the pump at relay R1 is specified here.
Setting range: 10 % to 95 % / Default setting: 30 %
Special functions
6.3.4. - Max.speed
6.3.5. - Min. speed
When the heat meter mode “Constant flow rate“ is selected, an approximated heat quantity
is calculated using the values the user has to enter. These are type of glycol/antifreeze,
glycol portion and flow rate. These values are put into correlation with the temperature
data of selected sensors.
(choice in 6.7.5, 6.7.6 and 6.7.7).
6.7. - Heat quantity
Caution
The heat quantity measured in the mode “Constant flow rate” is a
calculated approximation for function control of the system.
This function turns heat metering on and off.
Setting range: ON, OFF /
Default setting:
OFF
6.7.1 - Heat metering

6.3.6. - Setpoint
This value is the control setpoint for Mode M3 (see 6.3.1. - Modes). If the value at
the collector sensor drops below this, the speed is reduced. If it rises above this, the
speed is increased.
Setting range: 0 to 90 °C / Default setting: 60 °C

6.3.7. - Temperature difference
This value is an adjustable temperature difference for Modes M1 and M2 (see 6.3.1
- Modes). If the measured temperature difference
Δ
T between reference sensors is
lower than this value, the speed is reduced. If it is higher, the speed is increased.
Setting range: 3-50 K / Default setting: 10 K
