Application and purpose
This electric sequencer controls the staged start-up of HVAC and refrigeration systems. It provides a single switching stage with an adjustable off-delay between one and 25 seconds. Installers use it to prevent compressor short-cycling and reduce inrush current on residential or light-commercial equipment.
Timing range
The auxiliary switch off-delay adjusts from one second minimum to 25 seconds maximum, while the on-delay spans 65 to 115 seconds. Selecting the correct off-delay within this window determines whether the sequencer matches the equipment manufacturer's required delay specification.
Electrical capacity
Rated for 10 amps full-load at 120 volts AC and seven amps at 240 volts AC, with locked-rotor ratings of 72 and 42 amps respectively. It comfortably handles typical single-phase compressor and fan motors but is not sized for larger three-phase loads or higher current applications.

Questions about this item
What does the 1-25 second off-time range mean for my HVAC system?
The auxiliary switch can delay its off cycle anywhere from 1 second up to 25 seconds, letting you stagger compressor or fan shutdown.
How do the 120 V and 240 V ratings limit the loads I can connect?
At 120 V the sequencer handles 10 A full-load and 72 A locked-rotor; at 240 V it handles 7 A full-load and 42 A locked-rotor.
Can I mount this sequencer vertically or must it be horizontal?
The unit is approved for both horizontal and vertical installation orientations.
