5.6 Operation modes
According to the chart in section 3.2 on page 9, the different pump versions have different
integrated functions, thus operation modes.
5.6.1 Fix speed models
These pumps are not equipped with a potentiometer knob; run on a constant speed if
energized, until reaching the power limit, then the speed may be reduced.
Timer controlled version is available, standby and air purge functions are not available.
5.6.2 Variable speed models
These pumps are equipped with a potentiometer knob, with which the speed can be controlled
stepless between a factory preset minimum and maximum value. For reference see the hydraulic
curves at the dedicated speeds based on the scaling of 1 - 7 on page
31.
Timer controlled version is available, standby and air purge functions are standard, except some
special OEM versions.
5.6.3 Fix speed models with fix value temperature control
These pumps are not equipped with a potentiometer knob; run on a constant speed if
energized, until reaching the factory preset temperature limit; it is around 36 °C (97 °F) as
default, then the pump stops and switches to standby mode. When the fluid cools back to
around 33 °C (91 °F) the pump restarts.
Timer controlled version is available, standby and air purge functions are not available.
5.6.4 Fix speed models with variable value temperature control
There are two versions:
• Adjustable switch off temperature (see
Figure 12 left side view). The desired switch off
temperature can be selected between 20-70 °C (68-158 °F) using the selector knob. The
pump stops when it reaches the set temperature (switches to standby mode). When the fluid
cools back with 3 °C (5.4 °F) under the switch off temperature, the pump restarts.
• Adjustable restart temperature (see
Figure 12 right side view). The factory preset
temperature limit is around 36 °C (97 °F) as default, reaching this value the pump stops and
switches to standby mode. The desired restart temperature can be selected between 33-
25 °C (91-77 °F) using the selector knob. When the fluid cools back to the set temperature,
the pump restarts.
Timer controlled version is available, standby and air purge functions are standard, except some
special OEM versions.
