If the measured temperature of the pump goes below the set level and the drive is in sleep
state, the frost protection starts the pump to operate at a constant frequency.
P3.13.10.2 TEMPERATURE SIGNAL (ID 1705)
Use this parameter to select the source of the temperature signal that is used for the Frost
Protection function.
P3.13.10.3 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 corresponds to the temperature of
-50...200 celsius degrees.
P3.13.10.4 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 corresponds to the temperature of
-50...200 celsius degrees.
P3.13.10.5 FROST PROTECTION TEMPERATURE (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.
P3.13.10.6 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.

EXTERNAL PID CONTROLLER
P3.14.1.1 ENABLE EXTERNAL PID (ID 1630)
Use this parameter to enable the PID controller.
NOTE!
This controller is for external use only. It can be used with an analoque output.
P3.14.1.2 START SIGNAL (ID 1049)
Use this parameter to set the signal for starting and stopping the PID controller 2 for
external usage.
NOTE!
If the PID2 controller is not enabled in the Basic menu for PID2, this parameter has
no effect.
