Low Temperature Shutdown on the Zimmatic BOSS
An independent guide from FixMyPivot, not from the manufacturer. Brand and panel names are here only so you can find your own equipment.
What it means
A shutdown that trips when the temperature reading drops below a set limit.
The limit is set in degrees on the pump setup screen. A stop in cold weather may be this option working as set. If it trips on a day that is not cold, compare the outside air temperature on the run screen with the real temperature. When the panel reads the temperature too low, the cause can be a panel setup setting rather than a bad sensor, and a dealer can confirm which.
This one stops the machine.
Reading the display and looking the machine over with every door and cover closed is fine. Anything past that means power shut off and locked out at the main disconnect first, and electrical checks belong to a dealer, an electrician, or someone qualified to be in the panel.
This is what it means on the Zimmatic BOSS. On a different panel the same light or message can mean something else. Wrong panel? Pick another Zimmatic panel.
Safety
Center pivots run on high voltage and heavy moving machinery. Shut off and lock out power at the main disconnect before you open a panel or touch anything electrical. If you are not sure, stop and call your local pivot dealer or a licensed electrician. These pages tell you what a code means. They do not replace a qualified technician, and the safety instructions that came with your equipment come first.
