Value Brand Electric Sequencer 1 Switch 30-90 Sec

SKU CH-CHNK-DVKDB

Controls HVAC and refrigeration sequencing with one switch adjustable from 30 to 90 seconds on and 1 to 30 seconds off

  • Reliable HVAC timing with 30 to 90 second on-delay
  • Handles 10 amps at 120 volts for standard circuits
  • Supports 72 amp locked-rotor current at 120 volts
  • Durable phenol formaldehyde body with copper and ferrum
  • Works in horizontal or vertical mounting orientations

Electric Sequencer for HVAC and Refrigeration

The Value Brand Electric Sequencer 1 Switch 30-90 Sec manages auxiliary switching in HVAC and refrigeration systems. It operates with a full load current of 10 A at 120V AC and 7 A at 240V AC. The sequencer handles locked rotor currents of 72 A at 120V AC and 42 A at 240V AC. It mounts in horizontal or vertical orientations.

Technicians needing single-switch timing control

This unit suits technicians who require one auxiliary switch with on delays of 30 to 90 seconds and off delays of 1 to 30 seconds. It is not for installers who need multiple independent switch circuits or different timing ranges. Buyers needing other voltage ratings or contact configurations should look at alternative controls.

Check system voltage and mounting space

Verify the supply voltage matches 120V AC or 240V AC before ordering. Confirm the available space accepts the sequencer body and cover made from phenol formaldehyde, copper and ferrum. Ensure the wiring can handle the stated full load and locked rotor currents. Review the Proposition 65 notices regarding chemical content.

Questions about this item

What voltage supply does the sequencer need to deliver its 10 A full-load rating?

The sequencer is rated for 10 A at 120 V AC and 7 A at 240 V AC, so it must be wired to a matching 120 V or 240 V AC supply.

Can the 30-to-90-second on delay be used with an existing 24 V thermostat circuit?

The published ratings are for 120 V and 240 V AC only; no 24 V control-circuit specifications are provided.

How can I confirm the sequencer is timing correctly after wiring it?

Power the circuit and measure the auxiliary switch — it should close between 30 and 90 seconds after the call for heat and open within 1 to 30 seconds after the call ends.
