Berko M601W Thermostat

The Berko M601W is a heavy-duty single pole line voltage thermostat designed specifically for demanding HVACR applications, including baseboard heaters and radiant cove heaters. Built with a sensitivity-tuned bi-metal snap-action mechanism, this SPST wall mount thermostat provides reliable temperature regulation between 45°F and 75°F. It is engineered to handle high-amperage loads, featuring a current rating of 22 Amps at 120/240V and 18 Amps at 277V, alongside a 125 VA pilot duty rating. The white rectangular housing includes a large, intuitive control knob for precise field adjustments, making it a staple for apartment construction and commercial retrofits. Technically optimized for resistive heating circuits, the Berko 098319841483 ensures consistent cycling without the complexity of electronic displays, maintaining high durability in high-traffic environments. This mechanical line voltage thermostat is a direct solution for technicians requiring a robust, 1-pole configuration that meets UL and CSA standards for safety and performance.

• High Capacity Switching: Rated for 22A at 240V, making it ideal for high-wattage electric baseboard and radiant heating systems.
• Precise Response: The bi-metal snap-action element offers sensitive thermal tracking to prevent significant floor-to-ceiling temperature swings.
• Universal Voltage Compatibility: Operates across 120V, 208V, 240V, and 277V circuits for maximum field flexibility.
• Contractor-Grade Durability: Mechanical design eliminates the need for batteries or complex programming, reducing long-term maintenance calls.

Is the Berko M601W compatible with fan-forced heaters?

While primarily designed for baseboard and radiant systems, it can be used for fan-forced units provided the total amperage does not exceed the 22A/18A rating; however, for optimal fan-forced performance, a thermostat with a built-in heat anticipator is often preferred.

What is the difference between a single pole (SPST) and double pole (DPST) for this model?

The M601W is a single pole (SPST) unit, meaning it breaks only one side of the power line and has a minimum "low" setting rather than a true "off" position. If local codes require a mechanical "off" position, consider the M602W double-pole version.

Can this thermostat be mounted in a standard electrical box?

Yes, the M601W is designed for standard vertical mount installation in a single-gang electrical box, fitting typical commercial and residential wiring configurations.
