Resideo by Honeywell R24AA1008 Electric Heat Sequencer Single Switch 1-20 Second On Timing

The Resideo R24AA1008 is a single-switch electric heat sequencer designed to control the staged operation of electric heating elements in HVAC systems. This solid-state positive temperature coefficient (PTC) heater features versatile mounting capabilities that allow installation in any position.

Key Features:

• On-time delay: 1 to 20 seconds; Off-time delay: 40 to 110 seconds
• Contact ratings up to 25 Amps at 120 or 240 Volts, and 12.5 Amps at 480 Volts
• Quick-connect terminals for fast, easy installation
• Shock and vibration resistant construction
• Operating temperature range: -40°F to 165°F (-40°C to 73.8°C)
• UL approved with CSA certification

This heat sequencer stages electric heat strips on timed delays to prevent all elements from energizing simultaneously, reducing inrush current, light flicker, and breaker trips while delivering smoother, more comfortable heat. The R24 Series sequencers replace a wide range of Resideo and competitive controls, allowing you to maintain less inventory on hand.

Note: This product must be installed by a qualified/licensed HVAC contractor with properly calibrated test equipment.
