Parameter description
When the differential condition is fulfilled, the R2 runs at full
speed for a setted time.
Minimum speed rate for the R2 pump is set. This setting is
only valid for the speed control of high efficiency circulation
pump.
Maximum rotation rate for the R2 pump is set. This setting is
only valid for the speed control of high efficiency circulation
pump.
A control signal is set, where the R2 pump will be switch-off.
This setting is only valid for high efficiency circulation pumps
with control line break detection.
You can set the operation mode of the R3 pump with a set-
ting.
0- ON/OFF mode is used exclusively for control of classic
pumps without speed control
1- RPM mode is used exclusively for speed control of classic
pumps
2- PWM mode is used exclusively for speed control of high
efficiency solar pumps with external PWM control signal
3- PWM, INVERTED mode is used exclusively for speed
control of high efficiency heating pumps with external PWM
control signal
4- 0-10 V mode is used exclusively for speed control of high
efficiency solar pumps with external analogue control signal
5- 10-0 V mode is used exclusively for speed control of high
efficiency heating pumps with external analogue control signal
Minimum speed rate (RPM) for the R3 pump is set. The
setting is only valid for the speed control of a classic circulati-
on pump.
Important! Minimum speed rate of a pump depends on the
characteristics of the hydraulic system and pump power. In
the case of an undersized pump it can happen that the pump
cannot overcome the initial resistance in the system at the
minimum speed rate. Setting of min. speed rate is detail
described in the manual.
When the differential condition is fulfilled, the R3 runs at full
speed for a setted time.
Minimum speed rate for the R3 pump is set. This setting is
only valid for the speed control of high efficiency circulation
pump.
Maximum rotation rate for the R3 pump is set. This setting is
only valid for the speed control of high efficiency circulation
pump.
A control signal is set, where the R3 pump will be switch-off.
This setting is only valid for high efficiency circulation pumps
with control line break detection.
This function is used to control the solid fuel boiler return-pipe
temperature if there is no sensor installed in the storage tank.
In setted time controller monitors boiler temperature rise of 2 °
C. If there is a rise of 2 °C detected the boiler circulation
pump is activated for a setted time.
