Nordyne 01-0837 Sequencer
The Nordyne 01-0837 Sequencer is a critical electric heat sequencer designed for precise staged control in electric furnaces and air handlers. Engineered as an OEM replacement part, it is technically identical to the ZC24A34-1 and serves as a direct cross-reference for various White-Rodgers and Klixon models. This single-timing, single-pole single-throw (SPST) device features a 24V heat sequencer input and is rated for heavy-duty resistive loads up to 25A at 240VAC. The internal PTC heater provides reliable contact timing, operating with a delay of 1-20 seconds On and 40-110 seconds Off. These specific timings prevent simultaneous energizing of high-amperage heating elements, protecting the circuit breaker from nuisance tripping and reducing the initial electrical load on the system. Built with multi-poise mounting and standard quick-connect terminals, the 01-0837 Nordyne ensuring seamless integration into existing control compartments.
Key Benefits- Precise Staging: The 1-20 On / 40-110 Off cycle ensures proper HVAC sequencer timing to manage electrical surges in high-capacity electric furnaces.
- PTC Reliability: Equipped with a solid-state PTC heater for voltage compensation and consistent operation across a wide range of ambient temperatures.
- Direct Compatibility: Functionally replaces the ZC24A34-1, White-Rodgers 24A34-1, and Klixon 60000 series, reducing the need for field modifications.
- Universal Mounting: Multi-poise design allows for installation in any orientation within the control cabinet.
How do I wire a Nordyne 01-0837 for a blower delay?
When used in an electric furnace, the M1 and M2 terminals are typically wired to the blower motor or fan relay. This ensures the fan delay activates within 20 seconds of a call for heat and continues to run for up to 110 seconds after the thermostat is satisfied, purging residual heat from the furnace heating elements.
Can I use this to replace a sequencer with multiple timings?
The 01-0837 is a single-pole sequencer. If your existing setup requires multiple independent switches (e.g., a two-stage or three-stage heater), you may need to use multiple units wired in series to replicate the original staged heating sequence.
Will this work with 480V systems?
Yes, while optimized for 120V and 240V applications, the 01-0837 contacts are rated for resistive loads up to 12.5A at 480VAC. Always verify the individual amp draw of your heating elements before installation.
