We have a 2002 Sundance Capri which we want to cool off for the summer. The spa seems to be functioning fine until we lower the temperature below 101. A few minutes after lowering the thermostat we get a "flo" error message and the entire contol panel shuts down. When we throw the breaker and reset the temp at 101 or above, the spa functions fine. None of the explanations for the flo message in the manual seem to explain this situation. Any help would be greatly appreciated since I really don't want to spend $120 for the tech to come out to the house if it is a fixable problem. Thanks.
