Compatibility Quick Check

Last updated: August 11, 2026

Use this quick check before buying to confirm Mysa for Baseboards will work in your home. For full wiring detail, see Wiring Requirements. For wattage limits, see Wattage & Amperage Limits.

You're likely compatible if:

  • You have an existing wall thermostat (not a dial on the heater itself)

  • Your heating system runs on 120V or 240V (line voltage)

  • You have electric baseboard, convection, fan-forced, or radiant heaters

  • Your thermostat gang box has 4 or more wires (two bundles)

Do you have a wall thermostat?

Mysa replaces an existing wall-mounted thermostat.
