P3.21.5.2 TEMPERATURE SIGNAL (ID 1705)
Use this parameter to select the source of the temperature signal that is used for the Frost
Protection function.
P3.21.5.3 TEMPERATURE SIGNAL MINIMUM (ID 1706)
Use this parameter to set the minimum value of the temperature signal.
For example, a temperature signal range of 4...20mA agrees to the temperature of
-50...200°C.
P3.21.5.4 TEMPERATURE SIGNAL MAXIMUM (ID 1707)
Use this parameter to set the maximum value of the temperature signal.
For example, a temperature signal range of 4...20mA agrees to the temperature of
-50...200°C.
P3.21.5.5 FROST PROTECTION TEMPERATURE LIMIT (ID 1708)
Use this parameter to set the temperature limit at which the drive starts.
If the temperature of the pump goes below this limit and the drive is in the sleep state, the
frost protection function starts the drive.
P3.21.5.6 FROST PROTECTION FREQUENCY (ID 1710)
Use this parameter to set the frequency reference of the drive that is used when the frost
protection function is activated.
V3.21.5.7 FROST TEMPERATURE MONITORING (ID 1711)
This monitoring value shows the value of the temperature signal that is used for Frost
Protection function.
10.21.6 FLOW SWITCH
P3.21.6.1 FLOW SWITCH (ID 15590)
Use this parameter to select the digital input signal that is the feedback signal from the Flow
Switch.
P3.21.6.2 FLOW SWITCH FAULT DELAY (ID 15585)
Use this parameter to set the time that the feedback signal from Flow Switch must stay
inactive before the Flow Switch fault occurs.
P3.21.6.3 FLOW SWITCH BYPASS AT START (ID 15586)
Use this parameter to set the time after which the Flow Switch supervision becomes active at
the start-up of the drive.
