Marley Engineered Products 5813-2001-000 Thermostat

For field technicians and contractors maintaining Q-Mark or Berko heating units, the Marley Engineered Products 5813-2001-000 Thermostat serves as the direct OEM replacement for residential and commercial wall heaters. This mechanical snap-action thermostat is engineered to handle line voltage applications without the need for additional relays or complex control boards. It features a single-pole single-throw (SPST) configuration, making it a rugged solution for high-traffic environments where digital complexity often leads to premature failure. Designed specifically for compatibility with CWH1000 and CWHDSAG series wall heaters, this Marley heating control ensures accurate sensing and consistent cycling to protect the heating element from unnecessary stress. The assembly is built for durability in harsh environments, providing a reliable point of control for electric baseboard heaters and fan-forced systems. When swapping out a legacy HVAC part, the 5813-2001-000 offers a simplified wiring installation that matches standard factory footprints, ensuring minimal downtime on the job site.

• OEM Compatibility: Specifically designed for Q-Mark/Berko CWH series wall heaters, ensuring proper fit and terminal alignment.
• Snap-Action Reliability: Mechanical switch design provides crisp, decisive cycling to reduce arcing and extend the life of the line voltage thermostat.
• Simplified Control: The non-programmable, large-knob interface is ideal for applications requiring straightforward temperature management.
• Heavy-Duty Construction: Built for industrial and commercial use cases where stability and resistance to debris are prioritized.

Common Questions

Is this thermostat compatible with 24V low-voltage systems?
No, this is a line voltage thermostat designed for use with 120V to 277V electric heating systems. Do not use this with 24V control circuits as it will not function correctly and may damage the heater.

Can I use the 5813-2001-000 for cooling applications?
This model is a heat-only, SPST thermostat. It is not designed to control cooling equipment or compressors; it is strictly intended for HVAC replacement in electric heater units.

How do I calibrate the heat anticipator on this assembly?
While many Marley thermostats include a built-in anticipator for closer temperature control, this mechanical unit is factory-calibrated for the specified CWH series. Ensure all wiring connections are secure to prevent resistance-based heating within the switch housing.
