MARS 33256 Sequencer
As a field technician, you know that staggered element activation is non-negotiable for protecting the electrical service on your residential or light commercial installs. The MARS 33256 Sequencer is a robust DPST time delay sequencer designed to manage the startup of heating elements and blowers with high precision. This unit features a 24V thermal actuator and dual-pole switching, ensuring that high-amperage loads are staged to prevent circuit breaker trips or significant line voltage drops. With its positive temperature coefficient (PTC) solid-state heater, it provides consistent thermal time delay performance even in fluctuating ambient temperatures. This HVAC heat sequencer is a direct cross-reference replacement for many OEM electric furnace sequencers, featuring high-quality quick-connect terminals for efficient terminal-to-terminal wiring. Whether you are troubleshooting a stuck heat relay or performing a full control board upgrade, the MARS 33256 offers the multi-stage control required for modern air handlers and heat pump backup systems.
Key Benefits:- DPST Configuration: Direct control of two separate circuits to manage heating elements and fan interlocks simultaneously.
- Thermal Delay Relay: Utilizes a specialized PTC bimetal disc to provide reliable staging and prevent simultaneous high-draw startups.
- Broad Compatibility: Engineered as a versatile HVAC replacement part for diverse brands, reducing the need for multiple truck-stock SKUs.
- Shock and Vibration Resistant: Built to withstand the harsh internal environment of a high-static air handler units.
- Flexible Mounting: Can be mounted in any position, simplifying retrofits in tight control cabinets.
- How do I verify the timing on a MARS 33256? Timing is typically 1-110 seconds for "on" and 1-110 seconds for "off," though specific bimetal responses vary based on ambient conditions and voltage.
- Can this replace a Honeywell or White-Rodgers sequencer? Yes, this is a standard universal sequencer replacement for most DPST applications; always verify the wiring diagram and terminal counts before installation.
- What happens if the internal PTC heater fails? If the heater fails, the contacts will not close (or stay closed), preventing the heating elements from energizing despite a 24V call from the thermostat.
