1. Product introduction
Time Delay Relay And Sequencer
Sequencers are field-proven devices for controlling the operation of heating elements and/or fans in electric furnaces and heat pumps.

A wide variety of bimetal disc and PTC combinations are available to provide a broad range of timings.
Applications: Electric furnaces, Baseboard heaters, Duct heaters, Suspension heaters, Heat pump blower and heating element control etc
Approval:UL,CUL
