Comfort Zone CZ600 Baseboard Heater
This unit is a plug-in baseboard space heater with an adjustable thermostat dial and multiple safety features. It is rated at 1,500 watts and is intended for medium-sized rooms.
- Features two heat settings and a variable thermostat dial for manual temperature control.
- Includes tip-over switch, overheat protection, and a stay-cool body for safer handling.
- Designed as a convection baseboard heater with quiet operation for bedrooms or offices.
For users seeking an integrated mechanical thermostat with a conventional rotary control, this model provides a factory-fitted dial that functions as the heater’s switch/thermostat interface. Compatibility is inherent since control is built into the unit.
Comfort Zone CZ650B Digital Baseboard Heater
This version offers a digital adjustable thermostat rather than a purely mechanical knob. It is also a 1,500-watt convection baseboard designed for similar room sizes as its mechanical counterpart.

- Digital thermostat display allows more precise setpoint control compared with a simple dial.
- Includes safety systems like tip-over and overheat protection and maintains quiet operation.
- Offers two heat settings and a user-friendly interface for on-unit temperature adjustments.
For situations where precise temperature setpoints and an on-unit electronic interface are preferred, the CZ650B replaces a knob-based switch with digital control, while retaining standard baseboard safety features.
Honeywell T410A1013 Wall Thermostat
The Honeywell T410A1013 is a line-voltage, two-wire wall-mounted thermostat designed to replace many older baseboard heater controls. It is a common solution for retrofit and repair projects.
- Specifically replaces T410A style two-wire thermostats used on many baseboard heaters.
- Provides color-coded 6-inch leads for easier installation into standard junction boxes.
- Uses a long-lasting micro switch mechanism intended for frequent switching cycles.
This thermostat is relevant where the objective is to replace a wall-mounted mechanical line-voltage thermostat rather than the heater’s built-in control. Ensure the voltage and wiring type match your heater before replacement.
2PCS Baseboard Heater Knob Replacement
These replacement knobs are marketed as accessory kits for baseboard heater controls. They are compact, packaged in sets of two, and designed for common D-shaft thermostats.

- Two knobs per package; outer diameter ~2 inches, D-opening sized approximately 1/4″ x 5/32″.
- Ribbed grip for tactile control; intended for left-front or right-front knob positions on compatible heaters.
- Lightweight and simple to replace, offering a direct cosmetic and functional swap for worn or broken knobs.
Suitable when the control mechanism is functioning but the knob is damaged or missing. Confirm shaft profile and mounting orientation before purchase to ensure fit.
Marley Baseboard Thermostat Knob
The Marley replacement knob is a single-unit option compatible with various baseboard heater brands. It is intended to match OEM fit and feel for many models with front-mounted knobs.
- Single knob included; ribbed sides for improved grip.
- Designed to fit multiple brands including Marley, Fahrenheat, Dayton, Qmark, and Berko in compatible configurations.
- Not compatible with units that have end-mounted knobs; intended for front-mounted shaft styles.
This knob is useful for targeted repairs when original manufacturer parts are preferred or when matching an existing panel layout is required.
Buying Guide: Choosing The Right Baseboard Heater Switch Or Knob
Selecting the correct baseboard heater switch or knob depends on the heater type, wiring, control preference, and safety requirements. The following factors provide structured guidance across common purchase scenarios.
Identify The Control Type
Determine whether the heater has a built-in thermostat (dial or digital) or uses a separate wall-mounted line-voltage thermostat. A built-in unit typically requires a matching knob or the heater’s control assembly, while a wall thermostat requires a direct electrical replacement like the Honeywell T410A1013.
Confirm Voltage And Wiring
Baseboard heaters commonly run on 120V or 240V line voltage. Replacement thermostats must match the voltage and wiring style (two-wire vs. three-wire). The Honeywell T410A1013 is a two-wire line-voltage replacement; match that to your heater’s wiring before purchasing.
Check Shaft Type And Mount Location
Replacement knobs vary by shaft profile. Common options include D-shaped shafts and round shafts with set screws. Confirm whether the knob mounts on the front panel or an end cap; many replacement knobs specify left-front/right-front compatibility and will not fit end-mounted controls.
Mechanical Versus Digital Control
Mechanical knobs provide tactile, simple control and are frequently used in basic convectors. Digital thermostats offer more precise setpoints and sometimes improved energy control. Choose digital if you want finer temperature precision; choose mechanical knobs for simplicity and compatibility with older units.
Safety And Certification
Ensure the replacement or heater is equipped with standard safety features: overheat protection, tip-over switches for portable units, and properly rated enclosures for line-voltage components. Look for units or replacement parts that meet applicable electrical safety standards for your region.
Durability And Switch Mechanism
Thermostats and knobs are mechanical components subjected to repeated cycles. Prefer parts with a proven switch mechanism or long-life micro switch if available. Honeywell’s micro switch mechanism is designed for frequent operation in retrofit scenarios.
Installation Considerations
Simple knob swaps require no electrical work beyond confirming fit. Replacing a wall thermostat or internal control may require turning off circuit power, verifying wiring colors, and following instructions or hiring a licensed electrician if unsure. Factory-fitted heater controls often simplify installation for end users.
Compatibility With Heater Models
Match replacement parts to the heater brand and model when possible. Generic knobs may fit multiple brands but verify shaft dimensions and mounting orientation. Manufacturer-specific knobs (e.g., Marley) can be preferable when available for exact fit.
Replacement Scenarios And Recommendations
- If The Knob Is Broken But The Switch Works: Replace With A Compatible Knob (2PCS Or Marley) Matching Shaft Size.
- If The Wall Thermostat Is Faulty: Replace With A Line-Voltage Thermostat Matching Wiring And Voltage (Consider Honeywell T410A1013 For Two-Wire Systems).
- If You Prefer Easier Temperature Control: Choose A Heater With A Digital Thermostat (Comfort Zone CZ650B) Or Replace The Wall Thermostat With A Digital Line-Voltage Unit If Compatible.
- For Safety Upgrades: Opt For Units With Built-In Overheat And Tip-Over Protection Or Replace Faulty Controls To Restore Safety Features.
Comparison Perspectives
From a compatibility standpoint, simple knobs (2PCS or Marley) are low-effort cosmetic and functional fixes when shafts match. From a control precision perspective, digital thermostats provide finer setpoints and may improve comfort control. From an electrical retrofit perspective, line-voltage wall thermostats like the Honeywell model are essential when replacing in-wall controls.
When choosing replacement switches or knobs, balance the needs for precise control, wiring compatibility, installation complexity, and safety. Confirm technical specifications (shaft dimensions, voltage, wiring type) prior to purchase to ensure a successful and safe replacement.
