Key functions
Flow temperature control
• Return temperature limitation
The controller automatically changes the
desired flow temperature to obtain an
acceptable return temperature when the
return temperature falls below or gets higher
than the set value. The return temperature
influence can be limited by the min. / max.
flow limitation.
Optimization
• Auto tuning
A function for automatically setting the
proportional band (Xp) and integration time
constant (Tn).
Safety functions
• Frost protection
The controller automatically switches
the circulation pump ON when the flow
temperature is lower than a user-defined
value (factory setting: 10 °C).
• Motor protection
The controller prevents unstable temperature
control thus resulting in a longer life of the
actuator.
• Pump exercise
Exercise of the pump to avoid blocking in
periods without heat demand.
