Common Questions

What is the primary function of the CESO130044-00 in a cooling system?
This relay is specifically programmed to delay the energizing or de-energizing of electrical loads, typically used to keep the blower running for a short period after the compressor stops to harvest remaining cooling capacity.

Can this relay be used as a universal HVAC delay timer?
While it functions on standard 24VAC control circuits, it is optimized as an OEM HVAC replacement part for Carrier-manufactured equipment to ensure the exact factory-specified delay intervals are maintained.

Does this part replace the old HN67ZZ002 model?
Yes, the CESO130044-00 is the direct engineering update and current factory-authorized replacement for the HN67ZZ002 relay.
