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.
Type of thermostat | Compatible? |
|---|---|
Wall thermostat mounted separately from the heater | ✅ Compatible |
Dial or controls built into the heater unit itself | ❌ Not compatible — no gang box to install Mysa into |
High voltage vs. low voltage
Mysa for Baseboards works with high-voltage (line voltage) systems only.
Wiring | Compatible? |
|---|---|
Thick wires connected with wire nuts (120V/240V) | ✅ Compatible |
Thin strands connecting directly to thermostat terminals (24V) | ❌ Not compatible — you need Mysa Smart Thermostat instead |
