Down & Up

Last night was one of those nights. At 2:45 AM, my frost alarm went off when the temperature hit 33.8 degrees. If it had been 11 PM, I would have jumped out of bed, turned on the pumps and gone back to sleep. As I looked at the display, the temperature climbed up to 34 degrees. At 3:15, the alarm sounded again. With the temperature hovering like that, I decided to hold off. At 5:15, the temperature rose to 35 degrees. Turning on the system would have wasted many thousands of gallons of precious water. It could have just as easily gone the other way!
