Robertshaw A30-2311 Commercial Cold Control

The A30-2311 control is designed to be wired in series with the cycling control. The capillary senses the evaporator temperature, as ice starts to accumulate on the evaporator. The control will shut off the compressor. The contacts open at 30 °F and stop the compressor. When the evaporator temperature reaches 60 °F the contacts close and restart the unit. WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects, or other reproductive harm.
