MARS 24010 Control

The MARS 24010 Control Center is a robust fan control center engineered for seamless low-voltage management of single and two-speed fan motors in commercial and residential HVAC applications. This DPDT relay and transformer assembly features a multi-tap primary supporting 120V, 208V, and 240V inputs, dropping down to a consistent 24V secondary output. Rated for 18A and up to a 3/4 HP motor, this 40VA transformer unit mounts directly to a standard 4-inch square electrical junction box, keeping line-voltage connections securely enclosed. The MARS 24010 utilizes color-coded, pre-stripped leads for the primary side and an accessible 5-screw terminal board for secondary connections, ensuring a clean and efficient field install. It serves as a direct professional-grade alternative to the Honeywell R8285A series, providing the same heavy-duty switching reliability needed for high-demand blowers and auxiliary circuits.

• Universal Compatibility: Multi-voltage primary (120/208/240V) makes it a versatile stock item for various job sites.
• Heavy-Duty Switching: Features a DPDT relay capable of handling 3/4 HP fan motors with an 18A rating.
• Streamlined Installation: Pre-stripped color-coded leads and a dedicated terminal board reduce termination errors.
• Compact Enclosure: Mounts on a 4-inch junction box cover to preserve space while maintaining UL 1585 compliance.

Common Questions

Can this replace a Honeywell R8285 series control center?
Yes, the MARS 24010 is a common replacement for the Honeywell R8285A1048 and similar fan centers, provided the electrical ratings and DPDT switching requirements match your system’s schematic.

Does this unit support two-speed fan motors?
Correct. The DPDT switching relay allows for the control of multiple fan speeds or auxiliary circuits typically found in heating and cooling configurations.

Is the transformer rated for high-wattage accessories?
The integrated 40VA transformer is designed to power the relay and standard 24V thermostat circuits; however, always verify the total VA draw of all connected low-voltage components to prevent overloading.
