Selection of substitute sensor to replace the T4 sensor.
This setting is used when there is no option to install or con-
nect the sensor.
Selection of substitute sensor to replace the T5 sensor.
This setting is used when there is no option to install or con-
nect the sensor.
Selection of substitute sensor to replace the T6 sensor.
This setting is used when there is no option to install or con-
nect the sensor.
Parameter description
You can set the operation mode of the R2 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 R2 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.
