I have an Aqualink RS4 that and the cold weather has activated the freeze protection. What I am noticing is that when the temperature is right at the set point, the pump is being turned on and off rapidly (as much as 15 to 20 times a minute). That can't be good for the motor. Is this a "feature" of the RS4 or does this indicate a failure mode. Another related issue is that after the freeze protection is activated, the programmed start times are ignored until I cycle through the service mode at the power panel.
Anyone seen this behavior before?
