A12 SERIES CONSTANT CUT-IN CONTROL
The Ranco A12 Controls provide a constant Cut-In feature. The constant Cut-
In design is generally used to provide an Off-Cycle defrost function. Each time
the control cycles off, the control contacts will remain “open” until the
evaporator is cleared of any frost that may have accumulated from the previou
s
“On” Cycle. The A12 constant Cut-In setting will be between 35° and 41° F.
(See Control Chart.)
Generally, medium refrigeration units without hot gas or electric defrost systems
will use a Constant Cut-In Control (A12 Series).
Rotating the Knob/Dial changes only the Cutout setting. The Cut-In setting
remains the same regardless of the Knob/Dial position.
