Carrier CESO130062-00 Relay 319825-402 Thermal Expansion Protection: Designed toThe Carrier CESO130062 00 Relay is a specialized OEM compressor time delay relay board engineered to manage critical sequencing in residential and commercial HVAC systems. This HVAC time delay control board acts as a safeguard against premature compressor failure by preventing short cycling through a fixed 3 minute delay. By bypassing the low pressure switch during the initial startup phase, this relay mitigates nuisance trips caused by temporary
