WARNING!
To avoid possible injury or death due to
electrical shock, open the power supply disconnect switch
and secure it in an open position during installation.

Low Water Temperature Cutout Setting
CXM or DXM Control
When antifreeze is selected, the FP1 jumper (JW3) should
be clipped to select the low temperature (antifreeze 13°F
[-10.6°C]) set point and avoid nuisance faults (see “Low
Water Temperature Cutout Selection” in this manual). NOTE:
Low water temperature operation requires extended range
equipment.
